2023-07-06 11:32:24

In the annealing state, 3003 3A21 Aluminum Tube Pipe their plasticity is very high. In the semi cold hardening, the plasticity is good, the cold is hardened, the plasticity is low, the corrosion resistance is good, the weldability is good, and the cutting property is bad. A low load part, such as an oil tank, a gasoline or a lubricating oil pipe, that requires high plasticity and good weldability, and is used in liquid or gas medium.
