PRODUCT CENTER
7475 T4 Aluminum Coil 7xxx series is mainly zinc, but sometimes a small amount of magnesium and copper are added. The superdural alloy contains zinc, lead, magnesium and copper alloys close to the hardness of steel. The extrusion speed is slower than that of Series 6 alloy, and the welding performance is better. 7005 and 7075 are the high grade of the 7 series and can be strengthened by heat treatment.
7475 T6 Aluminum Coil 7xxx series is mainly zinc, but sometimes a small amount of magnesium and copper are added. The superdural alloy contains zinc, lead, magnesium and copper alloys close to the hardness of steel. The extrusion speed is slower than that of Series 6 alloy, and the welding performance is better. 7005 and 7075 are the high grade of the 7 series and can be strengthened by heat treatment.
