Product Description

3A21 to Al-Mn series alloy, The 321 aluminum plate is the most widely used anticorrosive aluminum, the strength is not high (only slightly higher than the industrial pure aluminum) cannot be heat-treated and strengthened. 

The cold machining method is used to improve its mechanical properties. It has high plasticity in annealing condition, good plasticity in semi-cold hardening, low plasticity in cold hardening, good corrosion resistance, good weldability and poor cutting performance.

3A21 Aluminum Rolling Heat treatment:

Uniform annealing: heating 510~520℃;Insulation 4~6h; air cooling.
Fast annealing: heating 350~410℃;Insulation 30~120min; air or water cooling.
High temperature annealing: heating 350~500℃, rewind thickness≥6mm, Insulation 10~30min,<6mm, heat completely air or water cooling.
Low temperature annealing: heating 250~300℃; Insulation 1~3h, air or water cooling.

Status: aluminum and aluminum alloy pressing plate.(0.6~0.8mm,HX8 state)

Product Application

3A21 Aluminum Rolling Application

Mainly used for high plasticity and good weldability, such as aerospace, military equipment, and fixtures, automotive, transportation and production of propellant tank, and the skin, the end of the module frame welded structure, stents, such as welding parts, and catheter, such as working in a corrosive medium.
