Where is C360 most often used?

In high-volume machined parts such as fittings, valves, and connectors.

Welding is difficult due to lead content; brazing and soldering are preferred.

Why is C360 called Free-Cutting Brass?

Because its lead content improves m achinability, making it easy to cut on CNC m achines.

Introduction to Brass C360

What

Brass C360 (C36000) is often called Free-Cutting Brass because of its outstanding machinability, rated nearly 100%. Lead is added to improve chip breaking and reduce tool wear. It combines good strength and corrosion resistance with the ability to be machined into complex shapes efficiently, making it ideal for high-volume CNC production.

Advantages

Exceptional machinability, ideal for CNC lathes
Good strength and dimensional accuracy
Moderate corrosion resistance
Cost-effective for precision machined parts

Applications

Nuts, bolts, and fasteners
Valve and plumbing fittings
Electrical connectors
Precision machined automotive parts
