2021 Aluminum Coil
Description:
2021 Series Aluminum Coil:
2021 series aluminum coil for Al-Cu alloy, is widely used as a sort of anti-rust aluminum, the alloy strength isnt high (slightly above industrial pure aluminum), cant be heat treatment strengthening, that the use of cold processing method to enhance its mechanical properties: its high plasticity in annealing state, good plasticity in semi-cold hardening, low plasticity in cold hardening, good corrosion resistance, good weldability, poor machinability.
