Brass bars are alloys of copper and zinc. The simplest brass is the copper-zinc binary alloy, known as the simple brass or the common brass. The brass with different mechanical properties can be obtained by changing the content of zinc in brass. The higher the content of zinc in brass, the higher the strength and the lower the plasticity. The brass used in the industry contains no more than 45% zinc. If the zinc content is higher, it will be able to be used in various deep drawing and bending machines, such as pins, rivets, washers, nuts, conduits, barometers, screens, radiators, etc. With superior mechanical properties, superior plasticity in hot state, plasticity in cold state, good machinability, easy welding and welding, corrosion resistance, it is a popular brass variety.

Specification: Thickness: 1.0-200 mm, width: 305-600 mm. Hardness: O, 1/2H, 3/4H, H, EH, SH, etc.

Brass classification Brass data are called special brass if they are made up of more than two elements of a variety of alloys. For example, copper alloys consisting of lead, tin, manganese, nickel, iron and silicon. Brass has strong wear resistance. Special brass is also called special brass. It has high strength, high hardness and strong chemical corrosion resistance. In addition, the mechanical properties of cutting are also prominent. Seamless copper pipe drawn by brass has soft and strong wear resistance. Brass seamless tubes can be used in heat exchangers and condensers, high temperature pipelines and submarine transport pipelines. Manufacturing sheet metal, bar, pipe, forging machine, etc. Copper content in 62%-68%, strong plasticity, manufacturing pressure equipment, etc.

According to the different kinds of alloy elements contained in brass, brass can be divided into two types: popular brass and special brass. Brass for pressure processing is called deformed brass. Brass can be used for all kinds of deep drawing and bending machines, such as pins, rivets, washers, nuts, conduits, barometers, screens, radiators, etc. With superior mechanical properties, superior plasticity in hot state, plasticity in cold state, good machinability, easy welding and welding, corrosion resistance, it is a popular brass variety. The brittleness of brass leads to the deterioration of alloy properties. In order to improve some properties of brass, brass with other alloy elements on the basis of mono-brass is called special brass.

The commonly used alloying elements are silicon, aluminium, tin, lead, manganese, iron and nickel. Adding aluminium in brass can improve the obedience strength and corrosion resistance of brass, and decrease the plasticity slightly. Brass containing less than 4% aluminium has superior processing and forging properties. Adding 1% tin to brass can significantly improve its ability to resist freshwater and terrestrial atmospheric decay, so it is called "naval brass". Tin can also improve the cutting properties of brass.

The important goal of adding lead to brass is to improve the machinability and wear resistance. Lead has little effect on the strength of brass. Manganese brass has excellent mechanical properties, thermal stability and corrosion resistance. Adding aluminium to manganese brass can improve its properties and obtain bright castings. Brass can be divided into forging and pressure processing products.
