Prodsuct Introdsuction
One of the strongest of the aluminium alloys,7075 aluminium sheet provides great performance and superior corrosion resistance for our customers. Zinc is the primary alloying element of 7075 with 1 to 8 per cent of the material composed of zinc. It is precipitation hardened to strength levels comparable to steel. Aluminium alloys have strong corrosion resistance. At subzero temperatures, their strength increases, thus making them a useful low-temperature alloy. Their strength decreases if they are subjected to very high temperatures. The aluminium 7075 alloy has high strength.
