Steel and aluminum (2024)

Canada’s steel and aluminum industries are key contributors to the Canadian economy, providing well-paying jobs and key inputs for other major industries, including energy, advanced manufacturing, construction, and auto-making.

In 2021, the Canadian steel industry employed over 23,700 workers and contributed $2.8 billion to Canada’s gross domestic product (GDP). For the same year, the Canadian aluminum industry employed approximately 11,000 workers and contributed $3.4 billion to our GDP.

The Canadian and United States (U.S.) steel and aluminum industries are deeply integrated, and underpin continental supply chains that strengthen the global competitiveness of the North American economy. Canada is a longstanding safe and secure supplier of steel and aluminum to the U.S. defence industry.

Canada imports more steel from the U.S. than any other country in the world, accounting for nearly 45% of U.S. exports. In 2021, $17.4 billion of steel was traded between Canada and the United States.

On aluminum, Canada and the U.S. share a highly integrated market with combined trade of $16.9 billion in 2021. About 90% of Canada’s primary aluminum production is exported to the United States, where it is used as an important input for further processing into products for U.S. domestic and export markets.

U.S. tariffs on Canadian steel and aluminum

On June 1, 2018, the U.S. imposed a 25 percent tariff on imports of Canadian steel and a 10 percent tariff on imports of Canadian aluminum under Section 232 of the Trade Expansion Act, which relates to perceived effect of imports on U.S. national security. In response, Canada imposed retaliatory tariffs against a proportionate amount of imports from the United States.

On May 17, 2019, the U.S. and Canada issued a joint statement announcing the elimination of the Section 232 tariffs against Canada and Canada’s countermeasures against the U.S., and the end to all related WTO litigation.

On August 6, 2020, the U.S. announced the imposition of tariffs of 10 per cent on imports of certain aluminum products from Canada, which took effect on August 16, 2020.

On September 15, 2020, the U.S. Trade Representative announced the return of tariff-free treatment of Canadian aluminum, effective September 1, 2020.

Steel Safeguards

For the period from May 13, 2019 to October 24, 2021, the Government of Canada imposed final safeguards in the form of tariff rate quotas (TRQs) on imports of certain heavy plate and stainless steel wire goods. These TRQs were administered by Global Affairs Canada by way of shipment-specific imports permits. Subsequently to the expiry of these safeguard measures, importers are no longer required to apply for shipment-specific import permits to import subject goods free of the safeguard surtax, and are to use General Import Permit No. 80 or 81, as applicable, for their shipments.

General Import Permit – Aluminum Products

In the context of global conditions affecting trade in aluminum, the Government of Canada has deemed it necessary to enhance Canada’s aluminum import monitoring capabilities. The addition of aluminum to the Import Control List under Item 83 and the General Import Permit No. 83 – Aluminum Products, came into force on September 1, 2019.

General Import Permits – Carbon and Specialty Steel Products

The Government of Canada has deemed it necessary to enhance Canada’s steel import monitoring capabilities by adding a reporting and record keeping requirement to the steel General Import Permits No. 80 and 81. Please refer to theNotice to Importers, Serial No. 1032for detailed information on these amendments including import requirements and procedures.

As an enthusiast and expert in international trade, particularly in the steel and aluminum industries of North America, I've extensively studied the intricate relationships between Canada and the United States concerning import regulations, tariffs, and their economic impact. My expertise spans various sources including governmental announcements, trade policies, industry reports, and analyses of the steel and aluminum markets.

The relationship between Canada and the United States in the steel and aluminum sectors is deeply interconnected, with both countries contributing significantly to each other's economies. In 2021, the Canadian steel industry employed over 23,700 workers and contributed $2.8 billion to Canada’s GDP. Meanwhile, the Canadian aluminum industry employed around 11,000 workers and contributed $3.4 billion to the GDP.

A critical event in recent years was the imposition of tariffs by the United States under Section 232 of the Trade Expansion Act. The U.S. imposed a 25 percent tariff on Canadian steel and a 10 percent tariff on Canadian aluminum in 2018, citing perceived national security concerns. Canada responded with proportional retaliatory tariffs. Subsequently, both countries engaged in negotiations leading to the removal of these tariffs.

Despite this, the steel and aluminum industries faced fluctuations due to ongoing trade disputes. The U.S. imposed additional tariffs on certain aluminum products from Canada in August 2020, which were later rescinded in September 2020.

Import controls and monitoring have been crucial aspects. Canada implemented General Import Permits No. 80 and 81 for steel products and General Import Permit No. 83 for aluminum products to enhance monitoring capabilities and regulate imports effectively.

Furthermore, the steel safeguards imposed by Canada on certain steel goods via tariff rate quotas (TRQs) expired on October 24, 2021. Importers are now required to use General Import Permit No. 80 or 81 for importing subject goods free of the safeguard surtax.

Recent governmental initiatives focused on supporting and protecting the steel and aluminum industries, aiming to safeguard Canadian workers and prevent unfair trade practices through stringent enforcement measures and trade regulations.

Articles, statements, and addresses by government officials such as the Minister of Small Business, Export Promotion, and International Trade, the Deputy Prime Minister, and the Minister of Foreign Affairs highlight ongoing efforts to address issues related to tariffs, protection of industries, and ensuring fair trade practices.

The intricate nature of these topics involves a network of governmental policies, trade agreements, industrial relations, and economic considerations that are vital for understanding the dynamics and impacts within the steel and aluminum industries in the context of international trade between Canada and the United States.

FAQs

What do you get when you mix steel and aluminum? ›

When aluminum and stainless steel are used in an assembly together, the electrons from the aluminum will begin to transfer into the stainless steel. This results in the aluminum weakening. This weakened aluminum causes it to deteriorate at a much faster rate. This can lead to an extended life of the stainless steel.

What do aluminum and steel have in common? ›

Both stainless steel and aluminum offer excellent corrosion resistance when exposed to water or other mostly neutral fluids. Much like the chromium oxide layer on stainless steel, aluminum can form a passive aluminum oxide layer to help reduce corrosion risks.

What is the yield strength of steel and aluminum? ›

Yield Strength: Again, Steel holds the higher ground in this category. Yield strength of Steel is typically around 250 MPa (36,000 psi) for structural grades, while Aluminum yield strength tends to be around 40 MPa (5,800 psi).

What is the reaction between steel and aluminum? ›

It's well known that bringing the two metals into contact can cause corrosion. Corrosion develops when two dissimilar materials are combined in a corrosive electrolyte. This can occur when certain materials (such as aluminum) are in contact with stainless steel.

What happens if you mix all the metals together? ›

It will form an alloy. Provided you can avoid explosions due to instability it will become mixture while some will not mix at all because it requires certain temperature to form mixture with others. All metals can not be mixed together.

Can you put aluminum and steel together? ›

While solid-state joining processes like friction stud welding and flash butt welding can join aluminum and steel together, you will not be able to do this using GTAW or GMAW. In this case, it would be better to actually bolt the parts together.

Does steel and aluminum rust? ›

However, since aluminum doesn't contain iron or steel, it doesn't rust away in most conditions. But aluminum, when exposed to water and oxygen will very quickly corrode. Most can identify rusted steel from its familiar orange color. Aluminum corrosion actually looks white.

Which is stronger aluminum or steel? ›

STRENGTH. Despite being at risk for corrosion, steel is still harder than aluminum. While aluminum does increase in strength in colder environments, it is generally more prone to dents and scratches than steel. Steel is less likely to warp or bend from weight, force, or heat.

What is the strongest metal? ›

Tungsten

Tungsten, which is Swedish for "heavy stone," is the strongest metal in the world. It was identified as a new element in 1781. It is commonly used to make bullets and missiles, metal evaporation work, manufacturing of paints, creating electron and Television tubes, and making glass to metal seals.

How thick does aluminum have to be to be as strong as steel? ›

It can be concluded from equations (32) and (33) that the thicknesses of aluminum tube should be 3.5 and 11.8 times as thick as two types of steel tubes to satisfy the equivalent strength design, respectively.

Which is cheaper aluminium or steel? ›

Overall, while aluminum and steel each have their unique benefits, steel is both the stronger and cheaper of the two. However, the perfect type of steel for any given project depends on the custom metal components required for your specific project.

Which is heavier steel or aluminum? ›

Nevertheless, the strength of steel's tradeoff is that steel is much heavier/much denser than aluminum. Steel is typically 2.5 times denser than aluminum.

Does steel heat up faster than aluminum? ›

- Rolled Steel: Rolled steel has a higher specific heat capacity compared to aluminum. It takes more energy to raise the temperature of steel, and it also releases heat more slowly.

Will aluminum replace steel? ›

The Strongest Aluminum Alloys and Their Applications

Some of these have already replaced steel in specific applications since they provide sufficient strength for that purpose but also provide some advantages that steel cannot, such as low relative weight and improved corrosion resistance.

Does aluminum weld to steel? ›

You can weld aluminum to most metals easily through adhesive bonding or mechanical fastening. However, to weld aluminum to steel, special techniques are required. Directly arc welding metals such as steel, copper, magnesium, or titanium to aluminum produces very brittle intermetallic compounds.

What are the risks of mixing aluminium and steel dusts? ›

In particular, aluminium and steel dust, when combined in the correct proportions, can create thermite; simply leaving finely divided steel and aluminium dust together over time can lead to a fire as the mixture can self-ignite.

Does steel and aluminum spark? ›

With ferrous metals, the small particles are burning which we see as sparks. Aluminum rapidly forms a tough oxide layer when it comes into contact with air. This oxide layer prevents it from burning like steel does.

What happens when you mix aluminum and iron? ›

A simple answer assuming you are working only with pure iron powder and with pure aluminum powder. If these powders are mixed up and heated in an inert atmosphere or high vacuum till they reacted, you will get iron aluminides. Depending upon the amount of aluminum, you will get Fe3Al, FeAl, and FeAl3.
