Source Xin Metal Materials Co., Ltd. of Shenzhen City, mainly engaged in (1) beryllium copper, tungsten, copper, chromium zirconium copper, phosphor bronze, aluminum bronze, nickel silver, bronze, copper and other copper cup with disabilities; (2) 1060,1070,2011 , 2014,2017,2024,5005,5052,5754,5083,6011,6060,6262,6061,6063,6082,6A02,7003,7005,7075,7050 other brands of aluminum bars, aluminum tubes, aluminum square, hexagonal aluminum and aluminum and other aluminum; (3) GB GB1470-88 typical stereotype of the three raw materials extruded alloy 6063, 6061 low intensity ratio, extrusion is good, can be used for complex-shaped cross-sectional shape of the timber, corrosion resistance and surface treatment of all good. ? ② is a low-alloyed Al-Mg-Si-based alloy high plasticity. Has many valuable features:? 1. heat strengthened, high impact toughness of the missing may not be sensitive. ? 2. There is an excellent thermoplastic, high-speed extruded into complex structures - Thin various profiles or hollow forgings forged into complex structure, wide range of quenching temperature, low quench sensitivity, after extrusion and forging stripping , as long as the temperature is higher than the quenching temperature. Then quenched with water spray or wear method. Thin-walled parts (6 <3mm) can also carry out air quenching. ? 3. weldability and excellent corrosion resistance, no stress corrosion cracking tendency, in the heat treatment can be strengthened aluminum alloy, Al-Mg-Si alloy is only found no stress corrosion cracking of the alloy. 4. After processing the surface is very smooth and easy anodizing and coloring. The disadvantage is that if the parking period after quenching at room temperature adversely affect the aging, the strength will
