7075 Aluminum Rod

Introduction to 7075 Aluminum Rod

7075 aluminum rod is a high-performance aluminum alloy primarily alloyed with aluminum, zinc, magnesium, and copper. It features high strength, good machinability, and can be strengthened through heat treatment, making it an ideal choice for many high-stress applications.

Main Features of 7075 Aluminum Rod

• High Strength: One of the highest strength aluminum alloys, with tensile strength up to 570 MPa and yield strength around 480 MPa.
• Excellent Mechanical Properties: Suitable for high-load structural parts such as aircraft fuselages and wing beams.
• Heat-Treatable: Performs exceptionally well in the T6 condition.
• Corrosion Resistance: Slightly lower than other aluminum alloys, often requiring surface treatment for enhanced durability.
• Poor Weldability: Generally joined using mechanical methods instead of welding.
• Good Machinability: Suitable for cutting, extrusion, and other processing methods.
