What is 7075 Aluminum Bar? 

At the heart of this groundbreaking material is the 7075 aluminum alloy, composed primarily of aluminum, zinc, magnesium, and copper. The precise combination of these elements results in an alloy with exceptional strength and hardness. The “T6” tempering process further enhances its properties, making it one of the strongest aluminum alloys available.

Properties of 7075-grade Aluminum Bar

  • Superior Strength: The 7075 aluminum bar boasts a tensile strength of around 83,000 psi (570 MPa), making it comparable to many steel alloys. This remarkable strength enables it to withstand high-stress environments, making it ideal for critical aerospace and defense applications.
  • Low Density: Despite its impressive strength, 7075 aluminum remains lightweight due to its low density. This characteristic is a game-changer for the aerospace industry, where weight reduction directly translates to fuel efficiency and increased payload capacity.
  • Corrosion Resistance: The alloy’s composition provides excellent resistance to corrosion, ensuring longevity and durability even in harsh environments, such as marine and aerospace applications.
  • Machinability: 7075 aluminum bar stock is relatively easy to machine, allowing for intricate designs and precise manufacturing processes. This factor significantly reduces production lead times and costs.
  • Heat Treatability: The T6 tempering process increases strength and improves heat treatability. This means the material can be subjected to various heat treatments for further customization without compromising its inherent qualities.
