[China Aluminum Network] 7075 aluminum alloy is a cold forging alloy, high strength, far better than mild steel. 7075 aluminum alloy is one of the more powerful commercial alloys. General anti-corrosion properties, good mechanical properties and anode reactions. Fine grain makes for deeper drilling performance, enhanced tool wear resistance, and exceptional thread rolling. Its main physical properties: tensile strength 524Mpa, 0.2% yield strength 455Mpa: elongation 11%, elastic modulus E/Gpa: 71, hardness 150HB, density: 2810. Features: 1. High strength heat treatable alloy. 2. Good mechanical properties. 3. Usability is good. 4. Easy to process, good wear resistance. 5. Corrosion resistance and oxidation resistance are good. chemical composition: Silicon Si: 0.40 Iron Fe:0.50 Copper Cu: 1.2-2.0 Manganese Mn: 0.30 Magnesium Mg: 2.1-2.9 Chrome Cr: 0.18-0.28 Zinc Zn:5.1-6.1 Titanium Ti: 0.20 Aluminum Al: Balance Others: Single: 0.05 Total: 0.15
