7075 Aluminium Alloy

Product Details

Aluminum alloys have strong corrosion resistance. At subzero temperatures, their strength increases, thus making them a useful low-temperature alloy. Their strength decreases if they are subjected to very high temperatures. The aluminum 7075 alloy has high strength. Owing to our sound infrastructure facilities, we are successfully catering to the requirements of our clients by bringing forth a uniquely designed array of 7075 Aluminum Alloy. Designed and developed at our state-of-the-art manufacturing unit, these products are highly utilized for various applications. With the aid sophisticated machinery and cutting-edge technology, our products are manufactured utilizing quality-approved raw material. The following datasheet gives more details about the aluminum 7075 alloy.Chemical Composition: The following table shows the chemical composition of the aluminum 7075 alloy. Element Content (%) Aluminum, Al 90 Zinc, Zn 5.6 Magnesium, Mg 2.5 Copper, Cu 1.6 Chromium, Cr 0.23 Physical Properties:The physical properties of aluminum 7075 alloy are tabulated below. Properties Metric Imperial Density 2.8 g/cm3 0.101 lb/in3 Melting point 483°C 900°F Applications include: Aircraft fittings Gears and shafts Fuse parts Meter shafts and gears Missile parts Regulating valve parts Worm gears Keys Commercial aircraft Aerospace Defense equipment Machinability and Weldability: 7075 in the T6 condition has a machinability rating of 80% when compared to 2011 at 100%. Aluminum 7075 is can be formed in the annealed condition. and can be forged in the temperature range of 700 Degrees to 900 Degrees F. It should be solution heat treated following forging. Aluminum 7075 is a very poor choice for welding. Resistance welding is the only preferred method of joining 7075. Gas welding should be avoided and the use of arc welding may result in degradation of corrosion resistance. Corrosion: Moderate corrosion resistance The over aged -T73 and -T7351 tempers Offers good stress-corrosion cracking resistance as compared to the -T6 and -T651 tempers Heat Treating: 7075 may be solution annealed at 900 Degrees F for 2 hours at temperature, followed by a water quench. The alloy may then be given a precipitation hardening (aging) heat treatment. Anodizing: Good using commercially available methods The alloy can be both hard and clear-coat anodized Annealing: Annealing is done at 775 Degrees F, holding for 3 hours at temperature. Controlled cooling at 50F per hour should then be used down to 500F from which it can be air cooled. Aluminium Alloy 7075 offers the highest strength of the common screw machine alloys. The superior stress corrosion resistance of the T173 and T7351 tempers makes alloy 7075 a logical replacement for 2024, 2014 and 2017 in many of the most critical applications. The T6 and T651 tempers have fair machinability. Alloy 7075 is heavily utilized by the aircraft and ordnance industries because of its superior strength.
