Aluminum manganese welding wire 3A21

Aluminum welding wire standard:GB/T10858-2008

Welding wire diameter:1.2、1.6、2.0、2.4、3.0、4.0(mm)

Welding wire reel size:D300（9kg）、D270（7kg）、D200（2kg）、D100（0.5kg）

Packaging status:Coiled wire, straight strip, looped wire, barrel packaging

Characteristics of welding wire:It is a widely used anti rust aluminum alloy, which has low strength (slightly higher than industrial pure aluminum) and cannot be strengthened by heat treatment. Therefore, cold working method is used to improve its mechanical properties: it has high plasticity in the annealed state, good plasticity in semi cold work hardening, low plasticity in cold work hardening, good corrosion resistance, good weldability, and poor machinability.

Welding application:The main purpose is for low load parts that require high plasticity and good weldability to work in liquid or gas media, such as oil tanks, gasoline or lubricant conduits, various liquid containers, and other low load parts made by deep drawing. The wire is used to make rivets.
