Product introduction
Manufacturing process
1. Hot working: plastic deformation of metal or alloy within a certain temperature range without work hardening.
2. Cold working: plastic deformation of a metal or alloy at a work hardening temperature.
Work hardening: the treatment that changes the structure of a metal or alloy through cold work, and increases the strength and hardness of the metal or alloy, while the ductility usually decreases. Work hardening curve.
3. Annealing: heat treatment that softens the metal or alloy by eliminating the work hardening caused by cold working of the metal or alloy, or by making the metal or alloy recrystallize and/or the soluble components gather and precipitate from the solid solution.
4. Incomplete annealing: heat treatment that reduces the strength of cold-worked metal or alloy to the control index, but does not completely soften. Such as H22/H24/H26/H28, etc.
5. Homogenization: The process of heating a metal or alloy to a certain high temperature and holding it for a period of time, mainly through diffusion to eliminate or reduce chemical segregation.
6. Stabilization: heat treatment that enables the size, mechanical properties, microstructure or internal stress of the product to maintain stability during use, such as H32/H34/H36/H38, etc.
7. Natural aging: at room temperature, the alloy is strengthened by the spontaneous dissolution of soluble components in supersaturated solid solution.
8. Artificial aging: the heat treatment that strengthens the alloy through the dissolution of soluble components in supersaturated solid solution above room temperature.
9. Quenching: put the alloy heated to high temperature into the liquid or gaseous medium or contact with the solid, so as to keep part or all of the soluble components in the solid solution at the cooling rate, so as to cool the alloy.
10. Solution heat treatment: the alloy is heated to a proper temperature, and the temperature is kept at this temperature, so that the soluble components can fully enter the solid solution, and the soluble components remain in the solid solution in the supersaturated state after quenching.
 

Characteristic
Low density, the density of pure aluminum is 2700kg/m ³， About 1/3 of iron (the density of iron is 7800kg/m ³）
The weight and strength are not high. Although the strength of pure aluminum is not high, it can be doubled by cold processing, and further strengthened by adding alloy elements and heat treatment, its strength can be comparable to that of good alloy steel.
Easy to process, aluminum can be cast by any casting method. Aluminum has good plasticity and can be rolled into sheet and foil; Draw into pipes and filaments; Extruded into various profiles; It can be processed with various machine tools.
Corrosion resistance, the surface of aluminum and its alloys is easy to form a dense and solid oxidation protection film. This protective film makes aluminum have good resistance to atmospheric corrosion and water corrosion. It will be damaged only under the intense action of halogen ions and alkali ions. The corrosion resistance of aluminum alloy can be improved by adopting protective measures.
The conductivity and thermal conductivity of aluminum are good. The conductivity and thermal conductivity of aluminum are second only to silver, copper and gold.
If calculated by mass conductivity, its conductivity is twice that of copper
Strong reflectivity. The reflectivity of aluminum polished surface to white light is more than 80%. Aluminum has good reflectivity to infrared, ultraviolet, electromagnetic wave, thermal radiation, etc.
Non-magnetic, impact does not generate sparks, has sound absorption, and is resistant to nuclear radiation. The color is beautiful.
Pure aluminum melting point 660 ° C, thermal expansion coefficient 68.1x10-6m ³/ (m3.K)
