Product Detail


7075 T651 aluminium square flat bar, commonly used in CNC cutting and manufacturing parts, suitable for flying mechanism frames and high-strength parts. The 7 series aluminum alloy contains zinc and magnesium elements. Zinc is the main alloying element in this series, so the corrosion resistance is quite good. Adding a little magnesium alloy can make the material reach very high strength after heat treatment.


7075 T651 aluminium square flat bar
It is characterized by good plasticity after solution treatment, particularly good heat treatment strengthening effect, high strength below 150°C, and particularly good low temperature strength; poor welding performance; stress corrosion cracking tendency; need to be coated with aluminum or other Protect the use of processing. Two-stage aging can improve the alloy's ability to resist stress corrosion cracking. The plasticity in the annealed and just-quenched state is slightly lower than 2A12 in the same state and slightly better than 7A04. The static fatigue and notch sensitivity of the sheet are better than 7A04. The density is 2.85g/cm3.
