Introduction A7075 A7075 Aluminum is a cold forging aluminum alloy, high strength, far better than mild steel. 7075 is one of the most powerful commercial alloys. General corrosion resistance, good mechanical properties and the anode reaction. Fine grain makes better deep drilling, tool wear, thread rolling different. (Chuangtian Miss Lungtien 0755-85230966) A7075 aluminum and aluminum alloy aluminum basic characteristics of the very wide range of modern industrial applications, mainly due to its having the following characteristics: ▲ ▲ lightweight corrosion resistance, formability ▲ ▲ ▲ ▲ machinability strength of the surface treatment of conductive ▲ ▲ ▲ ease of processing non-toxic non-magnetic ▲ ▲ ▲ welding of low thermal conductivity, non-brittle ▲ ▲ ▲ reflex renewable A7075 main purpose of the aerospace industry, blow molding (bottles) mold, ultrasonic plastic welding mold, high child husband ball, shoe, paper and plastic molding, foam molding, lost wax mold, templates, fixtures, machinery and equipment, mold processing. For the production of high-end aluminum bicycle frames. A7075 features a high-strength heat treatable alloys.

Improve the alloy of zinc, magnesium content, the tensile strength will be further improved, but its resistance to stress corrosion and exfoliation corrosion will fall. Subjected to heat treatment, can reach very high strength characteristics. 7075 material is generally a small amount of copper, chromium and other alloys, which are based on A7075-especially the top grade aluminum alloy, known as the best product in aluminum alloy, high strength, far better than any soft steel.

The main alloying elements are copper, silicon, magnesium, zinc, manganese, minor alloying elements are nickel, iron, titanium, chromium, lithium and so on. Low-density aluminum alloy, but the intensity is relatively high, close to or exceed the high quality steel, plastic, can be processed into a variety of profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, second only to the use of steel . Aluminum divided into two categories: cast aluminum alloy, the use of the cast; wrought aluminum alloy, can withstand pressure processing, mechanical properties than cast. Processed into various forms, specifications of aluminum material. Mainly used in the manufacture of aviation equipment, daily necessities, building doors and windows.

Aluminum alloy processing methods can be divided into deformed aluminum and cast aluminum. Deformation is divided into non-heat-strengthened aluminum alloy aluminum alloy and heat-strengthened aluminum. Enhanced heat treatment can not by heat treatment to improve the mechanical properties, can only be achieved by cold deformation strengthening, which includes high purity aluminum, industrial high purity aluminum, industrial aluminum and rust-proof aluminum. Heat-treated aluminum alloy can improve the mechanical properties by quenching and aging heat treatment, it can be divided into hard aluminum, wrought aluminum, super-hard aluminum and special alloy and so on. Some aluminum alloys can be heat-treated to obtain good mechanical properties, physical properties and corrosion resistance.
