[China Aluminum Network] what aluminum brass it?
Copper, zinc alloys contain aluminum, silicon, manganese, lead, tin and other elements to form a special brass. Such as lead brass, tin brass, aluminum brass, silicon brass, manganese brass.
Lead brass has excellent cutting performance and good wear resistance. It is widely used in the manufacture of watch parts and is used to make bearings and bushes.
Tin brass has good corrosion resistance and is widely used for manufacturing sea-going parts.
Aluminum brass can increase the strength and hardness of brass and increase the corrosion resistance in the atmosphere. Aluminum brass is used to make corrosion resistant parts.
Silicon in silicon brass can improve the mechanical properties of copper, wear resistance and corrosion resistance, silicon brass is mainly used for the manufacture of sea-ship parts and chemical machinery parts.
What are the main features of aluminum brass?
Aluminum brass has strong wear resistance. It has high strength, high hardness and chemical resistance. There are also prominent cutting machine performance. Seamless brass pipe drawn from aluminum brass, soft, strong wear resistance. Aluminum brass seamless tubes can be used for heat exchangers and condensers, cryogenic lines, and subsea transport tubes. Manufacturing of sheets, bars, bars, tubes, cast parts, etc. Copper containing 62% ~ 68%, strong plastic, pressure equipment and other equipment.
What are the uses of aluminum brass?
Aluminum brass can increase the strength and hardness of brass and increase the corrosion resistance in the atmosphere. Aluminum brass is used to make corrosion resistant parts.

What are the applications of aluminum brass?
The main alloy composition of aluminum brass is Cu-Zn-Al. In practical applications, in order to increase the strength, corrosion resistance, and wear resistance of aluminum brass, elements such as As, Mn, Fe, and Ni are often added to the alloy, thereby greatly improving the material. Comprehensive performance. Because of the equivalent weight coefficient of aluminum and zinc, the formation of β-phase tends to be larger and the strengthening effect is good. When the aluminum content increases, the γ-phase will appear. Although the hardness of the alloy is increased, the plasticity is drastically reduced. In aluminum brass, the aluminum surface tends to have a higher ionization tendency than zinc, and a dense and hard aluminum oxide film is preferentially formed to prevent the further oxidation of the alloy and increase the corrosion resistance to gases and solutions, particularly high-speed seawater.
