Description of Pipes from Aluminium Alloy 7050 (UNS A97050)
Aluminium alloy 7050 meets mechanical strength requirements and exhibits corrosion resistance in line with established specifications. It is formulated for low‐temperature applications and undergoes strength enhancement during standard thermal treatments. In this alloy, zinc is utilised as the primary alloying element, thereby ensuring the retention of mechanical performance over prolonged periods. Owing to its mechanical strength, low density, defined thermal properties and capacity to achieve a gloss finish, 7050 is used in the manufacture of forming tools.
