Usage

Definition

Different sources of media describe the Definition of 63338-02-3 differently. You can refer to the following data:
1. Any of a group of copper–zinc alloys containing up to 50% of zinc. The color of brass changes from red-gold to golden to silvery-white with increasing zinc content. Brasses are easy to work and resist corrosion well. Brasses with up to 35% zinc can be worked cold and are specially suited for rolling into sheets, drawing into wire, and making into tubes. Brasses with 35–46% zinc are harder and stronger but less ductile; they require hot working (e.g. forging). The properties of brass can be improved by the addition of other elements; lead improves its ability to be machined, while aluminum and tin increase its corrosion resistance.
2. A group of alloys consistingof copper and zinc. A typical yellowbrass might contain about 67% copperand 33% zinc.
