The brass rod is a rod-like object made of an alloy of copper and zinc, named after its yellow color. Brass with a copper content of 56% to 68% has a melting point of 934 to 967 degrees. Brass has good mechanical properties and wear resistance, and can be used to manufacture precision instruments, parts of ships, and shells of guns.
Different zinc content will also have different colors. For example, if the zinc content is 18%-20%, it will be red-yellow, and if the zinc content is 20%-30%, it will be brown-yellow. In addition, the sound of brass is unique, so Eastern gongs, cymbals, bells, horns and other musical instruments, as well as Western brass instruments, are all made of brass.
Classification
Materials are: H59, H59-1, H59-2, H59-3, H60, H60-2, H62, H63, H65, H68, H70, H80, H90; C1100, C1020, C2680, C2800, C2600, C2801, C5191 , C5210, C2200, C7521, C7541, C17200, C1070, C7701, QSn6.5-0.1, QSn8-0.3, QSn4-0.3, BZn18-18, BZn15-20, CuBe2 and many other materials.
58-3 copper rod, 59-1 copper rod is free-cutting brass, divided into environmental protection brass rod and ordinary brass rod. Generally, the authentic 58-3 copper rods and 59-1 copper rods are extruded. The copper rods produced by ordinary continuous casting copper rods cannot reach all aspects. The copper rods of the extrusion process have good tensile properties. High hardness and high straightness. Generally, there is a relatively large amount of precision copper parts such as auto parts, medical accessories, and electrical accessories.
Scope of application
Air conditioning pipes, refrigerator pipes, oil pipes, water supply pipes and various mechanical supporting materials, auto synchronizer gear rings, marine pumps, valves, structural parts, friction accessories, etc.
