Product Character
Brass is a copper zinc alloy which is basically used for hot or cold formed products. Higher thermal conductivity of brass makes it ideal for heat exchangers. Altering the composition of the alloy allows brass to change into desired colors preferred by architects.
Brass is a binary alloy composed of copper and zinc that has been produced for millennia and is valued for its workability, hardness, corrosion resistance and attractive appearance.
Class | Copper (%) | Zinc (%) | Notes | |||||
Alpha brasses | >65 | <35 | Alpha brasses are malleable, can be worked cold, and are used in pressing, forging, or similar applications. They contain only one phase, with face-centered cubic crystal structure. | |||||
Alpha-beta brasses | 55–65 | 35–45 | Also called duplex brasses. Suited for hot working. It contains both α and β' phase; the β'-phase is body-centered cubic and is harder and stronger than α. Alpha-beta brasses are usually worked hot. | |||||
Beta brasses | 50–55 | 45–50 | Can only be worked hot, and are harder, stronger, and suitable for casting. | |||||
White brass | <50 | >50 | Too brittle for general use. The term may also refer to certain types of nickel silver alloys as well as Cu-Zn-Sn alloys with high proportions (typically 40%+) of tin and/or zinc, as well as predominantly zinc casting alloys with copper additive. |
