6063 Aluminum Round Bar
The Introduction of 6063 aluminum round bar
6063 aluminum bars belong to low-alloy Al-Mg-Si series high plasticity alloys, known for their excellent surface finish, with excellent extrusion performance, good corrosion resistance and comprehensive mechanical properties, and are susceptible to oxidization discoloration.
The Product Features of 6063 aluminum Round Bar
● Strengthened through heat treatment with high impact toughness and insensitive to notches.
● Excellent thermoplasticity, can be extruded at high speeds into complex structural shapes, thin-walled and hollow sections, or forged into complex structural forgings.
● Excellent weldability and corrosion resistance with no tendency to stress corrosion cracking. Among heat-treatable aluminum alloys, Al-Mg-Si alloys are the only alloys where stress corrosion cracking has not been observed.
● Processed surfaces are very smooth and readily anodized and colored.
