Aluminum Co., Ltd. Guangdong Marriott: alloy grades: 1070,3A21,5A02,6061,6063,6005,6082,7A04; US imports of aluminum (ALCOA) / rod, green aluminum / rod / tubes, specialty seamless tubes High rigidity aluminum alloy plate, a variety of aviation aluminum, ultrasonic special aluminum, aluminum all kinds of mold, ships for aluminum, special aluminum alloy. Seamless tubes: 6061/6063/2024/5056/5052 / NC5 / 7075 aluminum row / hexagonal rod Grade: 6061/6063/6262/6201/6020/6082/7075/7005/7003/2011/2024/2017 / 2014/5052/5056/5083/1100/1060/1070/1050/1435. Specifications: diameter 2-420, thickness 0.1GB ASTM JIS DIN OST standards, specifications 6-630mm seamless, Φ8 ~ Φ2010mm, thickness: 0.6mm ~ 30mm of pipe high strength aluminum hard, can be heat strengthened In annealing, quenching and thermal state just plasticity medium, good spot welding, gas welding and welding aluminum when there is a tendency among the formation of intergranular cracks; the tubes after quenching and work hardening cutting performance is still good, bad in the annealed state. Corrosion resistance is not high, often with anodized and painted or surface plus clad layer method to improve corrosion resistance. It can also be used as a mold material.
