7075 aluminum tube is a cold-treated forging alloy with high strength and hardness, which is far superior to low carbon steel. 7075 aluminum tube is one of the most powerful alloys in the industry, with common corrosion resistance of,, and good mechanical properties and anode reaction. Fine grains make deep drilling better. , the tool wear resistance is enhanced, the difference between thread rolling and weight is greater, when the density requirement is small, the preferred metal material has higher hardness requirements.
The 7075 anodizing aluminum tube tubing is gray. If there is no dyeing after hard oxidation, the pure primary color is gray white. If dyeing, the color of dyeing, such as can, any color that can be dyed after oxidation treatment, only hard anodizing, but the oxide film is thicker, because it is alumina, it is harder, known as hard oxidation.
7075 T6 anodized aluminum tube is an Alcoa grade aluminum alloy plate for precision machining / tooling. 7075 T6 anodized aluminum tubing has good plasticity and heat treatment strengthening effect after solution treatment. It has high strength below 150 ℃, especially good low temperature strength, poor weldability, stress corrosion cracking tendency, and double aging can improve SCC resistance.
Chemical composition: Si Si; 0.4 Fe; 0.5 Cu; 1.2-2.0 Mn; 0.3 mg; 2.1-2.9 Cr; Zn 0.18-0.28; 5.1-6.1 Ti;
The main alloy element of 7075 T6 anodized aluminum tube is zinc, which has high strength, good mechanical properties and anode reaction. It is mainly used to manufacture aircraft structures and other high stress structural components that need high strength and corrosion resistance, such as airfoil walls, purs on aircraft. Good solution after solution treatment, good heat treatment strengthening effect, good strength below 150 ℃, especially low temperature strength, poor weldability, stress corrosion cracking tendency. Also widely used in mold processing, mechanical equipment, fixtures and so on.
