What is Aluminium 7050 Bar and Rods?

The strength of Aluminium 7050 stems from its unique zinc and copper composition, which is further enhanced by a specialised tempering process. This gives the bar and rod forms truly impressive mechanical properties, including an exceptionally high strength-to-weight ratio. It boasts superior resistance to stress corrosion cracking, maintaining its integrity even in challenging environments. This combination makes it a heavier-duty alternative to many other alloys.
