Brass Parts 5 axis Machining CNC Machined Component

Brass Parts are actually pure brass or brass alloy parts obtained by various fabrication methods.Brass is an alloy composed of copper and zinc. Brass composed of copper and zinc is called ordinary brass. If it is a variety of alloys composed of two or more elements, it is called special brass. Brass has strong wear resistance, and ordinary brass is widely used, such as water tank belts, water supply and drainage pipes, medals, bellows, serpentine pipes, condenser pipes, bullet casings and various complex shaped stampings, small hardware, etc. . With the increase of zinc content from H63 to H59, they can withstand hot processing well, and are mostly used in various parts of machinery and electrical appliances, stamping parts and musical instruments.

Due to the different zinc content in brass, the mechanical properties are also different, and the mechanical properties of brass vary with the zinc content. For α brass, with the increase of zinc content, both σb and δ increase continuously. For (α+β) brass, the room temperature strength increases continuously until the zinc content increases to about 45%. If the zinc content is further increased, the strength decreases sharply due to the appearance of a more brittle r-phase (solid solution based on Cu5Zn8 compound) in the alloy structure. The room temperature plasticity of (α+β) brass always decreases with the increase of zinc content. Therefore, copper-zinc alloys containing more than 45% zinc have no practical value.
