CuZn37 Brass Bar
CUZN37 brass has a homogeneous single-phase structure, although it may still contain traces of phase under certain cooling conditions. As the phase is particularly malleable when cold, this makes strong deformation possible by stamping or rolling, for example. CUZN37 is also a brass often used for stamping. Of all brass types, CU ZN 37 is one of the best for polishing.
The stirring of CUZN37 brass is rather simple, which is not the case for its welding, like most brass (insufficient steam pressure).
Brass standards Cu Zn 37
At the international level, the standards are different and CU ZN37 is designated in several ways:
- France (AFNOR): Cu Zn 37 (or CUZN37)
- Germany (DIN): Cu Zn 37 (or CUZN37)
- Europe (EN): CW508L
- ASTM : C27200
CUZN37 and its applications
With excellent mechanical properties, very good flexural strength and low conductivity, the main fields of application for CUZN37 brass are :
- Watchmaking: dials, hands, ...
- Household appliances: resistance wires, ...
- Automotive: fuel injectors, ...
- The manufacture of musical instrument strings (guitar, ...)
- Heating applications
