Brass Cu Zn 15 also called Similor
CUZN15 brass is an alloy of copper and zinc, also known as C23000. As its name indicates, it is composed of 85% copper and 15% zinc. This alloy has a golden colour due to its composition and is also called Similor. CuZn15 is resistant and very ductile when cold, therefore suitable for all deformation work (bending, stamping and other cold forming). It is one of the most corrosion-resistant brass types. It is also very easily polished, nickel-plated or chrome-plated.
Cu Zn 15 : international standards
The standards of this alloy are different at the international level, it is designated in several ways:
- France (AFNOR): CuZn15
- Germany (DIN): CUZN15
- Europe (EN): CW502L
- ASTM : C23000
