Main characteristics and application scope

1. AL - Mn series alloy.

2. One of the most widely used antirust aluminum.

3. Strength is not high (slightly higher than that of industrial pure aluminum)

4. Can't heat treatment to strengthen, the cold working method is adopted to improve its mechanical properties.

5. In annealing state has high plasticity, in a cold work hardening plasticity is good, when the cold work hardening plasticity is low.

6. Good corrosion resistance, good weldability, cutting performance is not good.

7. Mainly used for high requirement of plasticity and weldability, working in a liquid or gas medium low load parts, such as fuel tank, gas or oil duct, and other various liquid containers made of deep drawing parts: small load wire used for rivet.

3003

Good forming property, high corrosion resistance, good weldability and conductivity, strength is higher than in 1100.

Widely used in kitchen utensils and appliances, food and chemical products processing and storage equipment, transportation of liquid products tank, tank, with thin plate processing all kinds of pressure vessel and piping, heat exchanger, rivets, welding wire, washing machine, cylinder, etc.
