Description of the Aluminium Alloy 7050 (UNS A97050) Bar
The aluminium alloy 7050 exhibits high tensile strength and acceptable corrosion resistance. It is a low‐temperature alloy that achieves increased strength under cooler conditions. Zinc serves as the primary alloying element, thereby ensuring the retention of strength over extended periods. Its low density, measured thermal properties and capacity to be polished to a high gloss enable its use in the manufacture of forming tools. The alloy is primarily applied in the aerospace industry.
