What Is Brass?
Brass is a copper-zinc alloy whose properties vary according to its chemical composition, manufacturing process and temper. Different brass compositions offer different combinations of strength, ductility, corrosion resistance, machinability and formability.
The proportion of copper and zinc, together with other alloying elements where present, influences how the material performs during machining, forming, joining and service.
Brass is particularly valued for its workability and suitability for manufacturing precision components. Certain grades are designed for excellent machining performance, while others are better suited to deep drawing, forming, forging or selected marine applications.
Common brass product forms include sheets, plates, strips, rods, bars, hex bars, tubes, wires and precision-machined components.
Selecting the right brass material depends on the component design, required dimensions, manufacturing process, operating environment and applicable material specification.
Why Is Brass Widely Used in Industrial Applications?
