6061-T651 aluminum alloy is premium alloy by pre-stretching heat treatment process; tough it does not have same high strength as 2XXX or 7XXX, yet it has more Mg and Si alloy features, with good anti-corrosion property, excellent weldability, superior machinability, excellent electroplating and high toughness; it is of dense materials without defect & easy polishing & color filming, with good oxidation effect; non deformation after machining.
Tensile Strength ?b( MPa): ≥343
Yiled Strength ?0.2(MPa): ≥318
Elongation δ5(%): ≥11
1. Good weldability;
