Aluminium alloy 7075 is a popular material widely used in aerospace and aviation industries due to its high strength-to-weight ratio, toughness, and corrosion resistance. The alloy is further processed into various shapes, including round bars/hex bars/square bars/forged bars, which are used in different applications.
Features of Aluminium Alloy 7075 Round Bars
Aluminium alloy 7075 round bars are known for their exceptional strength-to-weight ratio, making them ideal for high-stress applications. They also have excellent machinability, making them easy to cut and shape into different parts. They also exhibit high corrosion resistance, making them suitable for applications in harsh environments. These round bars are easy to weld, anodised, and painted in different colours and finishes.

Corrosion Resistance of Aluminium Alloy 7075 Hex Bars
Aluminium alloy 7075 hex bars have excellent corrosion resistance properties. They have a protective oxide layer on their surface, which prevents them from rusting, corroding or reacting with chemicals. The alloy also has high-stress cracking and fatigue resistance, so it is used to fabricate aircraft and spacecraft parts. The hex bars can withstand a wide range of pH levels and exposure to high temperatures and UV radiation.
Chemical Composition of Aluminium Alloy 7075 Square Bars
Aluminium alloy 7075 square bars have a unique combination of chemical elements, giving them high strength and toughness. The alloy comprises zinc, magnesium, copper, chromium, and silicon, which work together to give it its exceptional strength-to-weight ratio. The square bars also have a low percentage of iron, reducing their corrosion susceptibility. The chemical composition can be adjusted to create different grades based on the specific application requirements.
Heat Treatment of Aluminium Alloy 7075 Forged Bars
Aluminium alloy 7075 forged bars can be heat-treated to improve their strength and durability. The heat treatment involves heating the bars to a specific temperature and then cooling them at a specific rate. This process can increase their yield strength, making them suitable for high-stress applications. The alloy can also be quenched and aged to further improve its hardness and tensile strength.
