6063 Overview ① aluminum alloy material. The main alloying elements of magnesium and silicon, with excellent processing performance, excellent weldability, extrusion resistance and plating resistance, good corrosion resistance, toughness, easy polishing, color film, anodizing excellent effect is typical extruded alloy. 6063 aluminum profiles with good ductility, heat treatment of moderate strength, good weldability and anodizing treatment, the surface of gorgeous color, and many other advantages of being widely used in building profiles, irrigation pipes for a vehicle, bench, furniture , lifts, fences etc. with the tubes, rods, profiles. ② is a low-alloyed Al-Mg-Si-based alloy high plasticity. It has many valuable features: 1. heat strengthened, high impact toughness, may not be sensitive to lack. 2. There is an excellent thermoplastic extruded into complex high-speed, thin-walled, hollow of various profiles, or forged into complex forgings. Quenching temperature range, low quench sensitivity, after extrusion and forging a release, as long as the temperature is higher than the quenching temperature, you can use water or through water quenching method. Thin-walled parts (δ <3mm) can also carry out air quenching. 3. welding performance and excellent corrosion resistance, no stress corrosion cracking tendency, in the heat treatment strengthened aluminum alloy, Al-Mg-Si based alloy is not the only discovery of stress corrosion cracking of the alloy. 4. After processing the surface is very smooth and easy to anodizing and coloring. The disadvantage is that after quenching, if parked for some time at room temperature in an adverse impact on aging (parked effect) have strength. 6063 density of 2.69g / cm3. 6063 hardness is 95HB. 6063 aluminum alloy chemical composition of Al Al: margin silicon Si: 0.20 ~ 0.6 Cu Cu: ≤0.10 magnesium Mg: 0.45 ~ 0.9 Zinc Zn: ≤0.10 Mn Mn: ≤0.10 Titanium Ti: ≤0.10 chromium Cr: ≤0.10 iron Fe: 0.000 to 0.350 Note: Single: ≤0.05; Total: ≤0.15 6063 Mechanical Properties of Aluminum Tensile strength σb (MPa): ≥205 Conditions yield strength σ0.2 (MPa): ≥170 Elongation δ5 (%): ≥ 9 Note: longitudinal bars at room temperature mechanical properties of the sample size: bar diameter (square bar, hexagonal bar inscribed circle diameter) ≤25 6063 use application strip is widely used in decoration, packaging, construction, transportation, electronics, aviation, aerospace, weapons and other industries. Representative applications include aerospace fixtures, electrical fixtures, communications, also widely used in automated machinery parts, precision machining, mold manufacturing, electronics and precision instruments, SMT, PC board solder vehicles and so on.
