6061 aluminum alloy is Al-Mg-Si alloy; with temper 6, it can be reinforced by heat treatment; with good shaping property, anti-corrosion property, weldability, machinability, extrusion, electroplating and toughness, easy polishing & color filming, with good anodizing oxidation effect; it is typical extrusion alloy of middle strength; it also can maintain good operability after annealing.
Tensile Strength ?b( MPa): ≥290
Yiled Strength ?0.2(MPa): ≥240
Elongation δ5(%): ≥10
1. Common hard aluminum alloy, good machinability, with middle strength;
2. Good shaping property, good welding property, good extrusion and electroplating property,
3. Good anti-corrosion and toughness, easy polishing and color filming;
4. Non-deformation after machining, easy coating, with good anodizing oxidation effect.
6061 alloy is widely used in aluminum doors & windows curtain wall frames in building industry. It is also widely used in other industries such as automobile, shipping, aviation, aerospace, electrical appliances, agriculture, electromechanical, home industry etc. aluminum tube is now very where can be seen.
