Application introduction of 3 series alloy aluminum strip

A.Basic introduction of alloy aluminum strip

The 3 series aluminum alloy is also called an aluminum-manganese alloy.

The content of manganese is 1-1.5%. It is a widely used anti-rust aluminum alloy series.

The strength of the 3 series aluminum alloy is higher than that of pure aluminum alloy, although it cannot heat treat to strengthen the performance.

But it has good plasticity after cold working (under-cold rolling mill) and annealing process.

Because of its good corrosion resistance and welding performance can be used in many industries,

such as the building decoration industry and the electronic manufacturing industry.

Automobile manufacturing, etc.

B.3 series alloy aluminum strip

The main brands commonly used in 3 series aluminum alloys are 3003 aluminum plate, 3004 aluminum plate, 3104 aluminum plate, 3005 aluminum plate, 3105 aluminum plate.

Among them, 3003 aluminum alloy is the most used. The 3003 aluminum plate is easy to process and has good rust resistance.

It can use to roll paint on the original aluminum to make various decorative curtain wall panels and aluminum ceiling gussets for indoor use.

The roof color aluminum tile made by bending by the tile press, which is light and durable and has a service life better than steel.

C.

The price of 3003 is cheaper than that of 5052, and the welding performance is also very good.

Some truck fuel tank material manufacturers also use 3003H24 aluminum plates to replace the pressure-bearing partitions in the 5052 fuel tanks, reducing costs without affecting the use.

The strength of 3004 alloy is higher than that of 3003, and the forming performance is better.

It can use as the body of all-aluminum cans and as a device for chemical production and storage of liquids.

3104 alloy and 3004 alloys are very similar in composition, high in strength, and easy to process.

In the TV manufacturing industry, 3104-O state plates often use to make TV LCD backplanes,

punch convex hulls, add electronic components, and form dense oxidation after molding and oxidation.

The film is not only resistant to corrosion and oxidation but also has good insulation,

which reduces the total weight of the finished product and ensures good heat dissipation performance.

3005 alloy is mostly used in relatively high-end color-coated aluminum coils,

in the building materials industry, roof partitions, movable panel houses, etc.,

and can also use to make air conditioners, refrigerators, and other heat sinks, internal parts, etc.

3105 alloys can mainly use to make punched parts such as bottle caps and caps.
