(UNS A97075)7075 aluminum bar is an aviation aluminum bar forged from cold-worked or extruded aluminum alloy with high strength, good machinability, and good stress corrosion control. Fine grain control allows for good tool wear.
7075 is one of the strongest aluminum alloys. It has good fatigue strength and average machinability. It is often used where parts are subject to high stress. It is not weldable and is not as corrosion-resistant as other aluminum alloys. Mechanical properties depend on the tempering of the material. Commonly used in the bicycle industry, aircraft structures, and rifles for the US military.
We have 7075-T651, 7075-T6511, 7075-T7351, 7075-T3511, and 7075-T76511 aluminum bars in stock. If you need to buy 7075 aluminum bars, please contact us directly for more product information and prices!

Product Introduction of 7075 Aluminum Bars
1, 7075 aluminum alloy is a cold treatment forging alloy, high strength, far better than soft steel. 7075 is one of the most powerful alloys available in commercial use. Subjected to heat treatment, it can achieve very high strength characteristics. 7075 material is generally added a small amount of copper, chromium, and other alloys, the series of 7075-T651 aluminum alloy is particularly high-quality, known as the best product in aluminum alloy, high strength, and far better than any soft steel. This alloy also has good mechanical properties and anode reaction.
2, 7075 mainly contains zinc elements. Also belongs to the aviation series, is aluminum magnesium zinc copper alloy, is a heat treatable alloy, belongs to super hard aluminum alloy, and has good wear resistance.7075 aluminum bar is stress-eliminated, and will not deform, or warp after processing. All the large and ultra-thick 7075 aluminum bars have been detected by ultrasonic waves, which can ensure that there are no sand holes and impurities. The thermal conductivity of the 7075 aluminum bar is high, which can shorten the molding time and improve work efficiency.
The main feature is that the hardness of 7075 is a high hardness, high-strength aluminum alloy, commonly used in the manufacture of aircraft structures and futures. It requires high strength, corrosion resistance high-stress structural parts, and mold manufacturing.
