7075 aluminum sheet belongs to Al-Zn-Mg-Cu series super hard aluminum, it is a kind of cold treatment forging aluminum alloy with high strength, super hardness which is much better than that of soft steel. The temper of 7075 aluminum sheet is manly O, T8, T651, T7451an so on. The thickness is 1.0- 800mm, the width is less than 1500mm, the length is more than 8000mm. 7075 aluminum sheet can be applied in aerospace Industry, high level phone, plastic mold, Ultrasonic plastic welding molds, golf balls, shoe molds, paper plastic molds, foaming molds, de-waxing molds, templates, fixtures, machinery equipment, mold processing, high-level aluminum alloy bicycle frames and other fields.
7075 aluminum sheet is one of the most commercially-available alloys with common corrosion resistance, good mechanical properties and anodic reaction. Fine grains make the performance of deep drilling better, tool wear resistance increases. When choosing alloy which density is required small and the hardness is high, 7075 aluminum is a good choice. 7075 aluminum alloy has zinc alloy as the main element, but sometimes also added a small amount of magnesium, copper. The super-hard aluminum alloy containing zinc, lead, magnesium and copper alloys, the hardness is close to steel, heat treatment can be enhanced, corrosion resistance is common, mechanical properties are good.
