Clients trust Neil Metals for their corrosion-resistant, heat-treatable aluminium bars and rods, which strike the perfect balance between strength, toughness, and machinability in critical applications.
Aluminium 7050 Bars and Rods are high-strength aluminium alloys, primarily made up of about 90% aluminium, 5.7–6.7% zinc, 2.0–2.6% magnesium, and 2.0–2.6% copper. This unique blend provides them with remarkable strength, excellent resistance to stress corrosion cracking, and good toughness. These bars and rods boast a tensile strength of approximately 510–570 MPa, a yield strength of around 430–470 MPa, and impressive fatigue resistance. Aluminium 7050 is also heat-treatable and offers good machinability, making it an ideal choice for structural components where both strength and corrosion resistance are crucial in harsh environments.
