Introduction to Aluminum Bronze and Aluminum Brass
Release time: 2021-03-01 Publisher: Sanhe Machinery

Aluminum brass and aluminum bronze are also known to have significant differences in color, process characteristics, and uses.
Aluminum brass is a special brass (aluminum brass) formed by adding aluminum to copper zinc alloys.
1. The uses of aluminum brass
Aluminum in aluminum brass can improve the strength and hardness of brass, enhance its corrosion resistance in the atmosphere, and aluminum brass is used to manufacture corrosion-resistant parts
2. The main characteristics of aluminum brass
Aluminum brass has strong wear resistance. It has high strength, high hardness, and strong resistance to chemical corrosion. The mechanical performance of cutting and processing is also outstanding. Seamless copper pipe made of aluminum brass, with soft texture and strong wear resistance. Aluminum brass seamless pipes can be used for heat exchangers and condensers, low-temperature pipelines, and subsea transportation pipes. Manufacturing plates, bars, pipes, casting parts, etc. Containing 62%~68% copper, with strong plasticity, suitable for manufacturing pressure resistant equipment, etc.
3. Process characteristics of aluminum brass
The aluminum brass series is quite complex, and some complex aluminum brass contain third and fourth alloying elements such as manganese, nickel, silicon, cobalt, and arsenic. HAI66-6-3-2 and HAI61-4-3-1, which have more alloying elements, are both alloys composed of six elements. Some of the aluminum brass with complex processing is derived from special-shaped casting alloys.
Aluminum bronze is a copper based alloy with aluminum as the main alloying element, which is aluminum bronze containing iron and manganese elements and belongs to high-strength heat-resistant bronze.
1. The Use and Characteristics of Aluminum Bronze
The aluminum content generally does not exceed 11.5%, and sometimes an appropriate amount of elements such as iron, nickel, and manganese are added to further improve performance. Aluminum bronze can be strengthened through heat treatment, with higher strength than tin bronze and better resistance to high-temperature oxidation. High strength and good wear resistance are used for high-strength screws, nuts, copper sleeves, sealing rings, and wear-resistant components. The most prominent feature is its good wear resistance.
Aluminum bronze has high strength, hardness, and wear resistance, and is commonly used to manufacture gear blanks, threads, and other parts. Aluminum bronze has excellent corrosion resistance, so it can be used to manufacture corrosion-resistant parts such as propellers, valves, etc. Aluminum bronze does not produce sparks under impact and can be used to manufacture spark free tool materials. With excellent thermal conductivity and stable stiffness, it has become a new type of mold material that does not cause sticking or scratching of the workpiece when stretching and rolling stainless steel plate heat exchangers. Aluminum bronze has shape memory effect and has been developed as a shape memory alloy. Aluminum bronze alloy is relatively inexpensive and has become a partial substitute for some expensive metal materials, such as tin bronze, stainless steel, nickel based alloys, etc. It is precisely because of the excellent characteristics of aluminum bronze that it is increasingly favored and plays an important role in both civil and military industries.
2. The Process Characteristics of Aluminum Bronze
Aluminum bronze is more suitable for melting in medium and power frequency coreless induction furnaces. The biggest obstacle during melting in a power frequency cored induction furnace is that Al, O, or A1,0 are easily adhered to the wall of the melt groove. The slag composed of other oxides continuously reduces the effective cross-section of the melt groove until the entire cross-section of the melt groove is completely blocked by the slag.
The atmosphere of induction furnace melting is easy to control, and the melting speed is fast, which is conducive to reducing or even avoiding the danger of excessive hydrogen absorption and the generation of Al, O, which are difficult to discharge from the melt. Although very small Al and O may have a refining effect on crystallization, the greater harm is that Al and O may become
The root cause of layered fracture defects in processed products.
