Based in the industrious heart of Hamilton, New Zealand, Hemi Metals has built its reputation on delivering exceptional strength and reliability through its aluminium forgings. Our focus on Aluminium 7075 Forgings is a point of pride, offering components that meet the intense demands of high-stakes industries. We understand that your projects require materials that won’t falter under pressure, which is why our dedicated team is committed to providing a local source for this world-class, high-performance alloy, ensuring your designs are supported by superior quality and proven durability right from our own backyard.
Aluminium 7075 is renowned for its impressive strength, which is achieved through a primary composition of zinc, along with significant magnesium and copper. This specific blend allows it to be heat-treated to a level where its mechanical properties begin to rival many types of steel. The result is a forging that offers an outstanding strength-to-weight ratio, excellent fatigue resistance, and good mechanical toughness. It’s this powerful combination that makes 7075 the go-to choice when an application demands lightweight components without any sacrifice in structural integrity or performance.

Yes, Aluminum 7075 can be forged into shapes with tight tolerances. Its high strength allows for precise shaping, but careful control of temperature and pressure is required for optimal results.
Aluminum 7075 offers high strength, excellent fatigue resistance, low weight, good machinability, and corrosion resistance, making it ideal for custom forgings in aerospace, military, and high-performance applications.
Aluminum 7075 is not ideal for high-temperature forging applications due to its relatively low melting point and limited thermal stability. It is better suited for aerospace and structural applications at moderate temperatures.
The exceptional properties of Aluminium 7075 Forgings make them indispensable in fields where failure is not an option. You’ll find these robust components forming the backbone of aerospace structures, such as aircraft fuselage frames and wing spars. In the world of high-performance motorsports, they are crucial for critical parts like suspension components and gears. Beyond these, they are equally vital in demanding military equipment, high-end mountain biking, and even in the precise machinery used for automation and robotics, wherever a combination of light weight and immense strength is paramount.
