C36000 Free Cutting Brass Bar / C360 Brass / Free Machining Brass
C36000 Free Cutting Brass Bar / C360 Free Machining Brass
C36000 Brass is commonly known as "Free Cutting" or "Free Machining" Brass. With a machinability rating of 100 this material is the standard by which all other metals are measured by. The 2 phase structure of C360 tends to form broken chips instead of continous coils, which interfere with high speed machining. This brass alloy is suited for high speed machining. The lead content adds internal lubrication against the surface of the cutting tool. The high machinability rating of C36000 Free Machining Brass permits full utilization of screw machines speeds and feeds capabilities. C360 has superior machinability, thread rolling and knurling characteristics. In half hard condition, C360 brass can be a substitute for leaded steel in a majority of common screw machine products.
