3105 aluminum alloy sheet material introduction

What is alloy 3105?3105 aluminum plate is another common aluminum alloy plate in the 3000 series besides 3003 and 3004. 3105 aluminum alloy is a series of AL-Mn alloys, with all states such as O state, H12, H14, H18, H22, dll..
As a good anti-rust aluminum, 3105 aluminum plate has good electrical conductivity and mechanical properties, and it has high shear strength, tensile strength and yield strength.
Like 3004 plat aluminium, 3105 aluminum plate has excellent arc welding performance, and can accept gas welding, contact spot welding and wire welding. 3105 can be used for room partitions, baffles, movable room panels, gutters and downspouts, sheet metal forming parts, bottle caps and caps.

3105 aluminum plate product use

What is 3105 aluminum plate used for?3105 aluminum plate products have good rust resistance. It is often used in outer packaging, mechanical parts, refrigerators, air-conditioning ventilation ducts. There are also some humid environments, such as ships, ships, vehicle materials, automobile and aircraft plate welding parts, pressure vessels that require strict fire protection, refrigeration devices, TV towers, Drilling equipment, transportation equipment, missile elements, armor, dll..

The advantages of 3105 aluminum plate supplied by Huawei:

1. AL 3105 has certain corrosion resistance, strong stress corrosion cracking ability and long service life.
2.Aluminum sheet 3105 has strong plasticity, can be processed by hot and cold, and has certain brazing properties.
3. 3105 aluminum plate has good tensile strength, and the content of impurity element Cu is controlled below 0.2% during production, which not only improves the tensile strength of the alloy, but also does not affect the corrosion resistance of the alloy.
4.Aluminum 3105 sheet is widely used. 3105 is a widely used anti-rust aluminum, which is widely used and used in large quantities.

3105 H24 aluminum sheet vs 3003 H14 aluminum sheet

3105 and 3003 belong to the 3000 series aluminum alloy plate, but there are many differences between the two.

1. Alloy hardness: 3003 H14 has 42 BHN, 3105 H24 has 47 BHN.

2. In terms of fatigue strength: 3003 H14 has only 60 MPa, while 3105 H24 has 74 MPa.

3. In the alloy composition: 3003 H14 contains more magnesium than 3105 H24. But 3105 H24 contains small amounts of titanium, chromium and copper that 3003 H14 does not.
