7005 and 2024 t3 aluminum coil rolls are two representative of the hardest aluminium products. Their differences lie in chemical composition, mechanical properties and application. Chemical Composition 7005: Si：≤0.35 Fe：≤0.40 Cu：≤0.10 Mn：0.20~0.7 Mg：1.0~1.8 Cr：0.06~0.20 Zn：4.0~5.0 Zr：0.08~0.20 Ti：0.01~0.06 Al: rest 2024: Si: 0.5% Fe: 0.5% Copper: 3.8-4.9 Mn: 0.3-0.9 Mg: 1.2-1.8 Cr: 0.10 Zn: 0.25 Ti: 0.15 Other: 0.15 Al: rest …

7005 aluminum coil (Al-Zn-Mg-Cu) is a super-hard aluminium with great welding performance. Mainly used in aerospace, mold processing, machinery and equipment, fixtures and so on, 7005 aluminium alloy is a typical kind of light-weight aluminum. it can be heat strengthened, but is not stronger than 6061 aluminum coil. 7005 t6 aluminum sheet coil is a 7 series heat treatment alloy with …
