This is 1 1/4 Hexagon across the flats brass CZ121
CZ121 offers the highest possible machinability of any copper alloy.
FEATURES
This alloy is a free-machining brass with a 3% lead content – the addition of lead is finely dispersed throughout the microstructure of the material which acts as both a lubricant and chip breaker; this results in giving the alloy its free machining characteristics. With a machinability rating of 100%, CZ121 is the standard by which all other copper-based alloys are rated. The alloy also offers good corrosion resistance and strength.
SUITABILITY
CZ121 offers good corrosion resistance and good strength. The alloy promotes excellent hot formability with the highest machinability of any copper alloy.
TYPICAL APPLICATIONS
Commercial applications for this engineering material include:
- All types of machined components
- Fasteners
- Extruded sections
- Window frames
- Plug pins
- Switch blocks
