Our team understands the critical demands of local industries, providing not just a product, but reliable expertise and support. We are your dedicated New Zealand partner for materials that combine exceptional strength with the resilience needed to perform under the most challenging conditions.
Aluminium 7050 is renowned for its impressive strength, achieved through a primary composition of zinc, along with magnesium and copper. This specific blend gives the angles a remarkable toughness, making them significantly stronger than many other aluminium alloys. What truly sets 7050 apart is its exceptional resistance to stress corrosion cracking, a vital property for components under sustained tension. It also retains these superior mechanical properties even in very thick sections, ensuring consistent performance throughout the entire profile.
