Why Choose Brass C360?

Brass C360 is rated at 100% machinability—the benchmark against which all other metals are compared.

Best Machinability

100% machinability rating. Short chips, minimal tool wear, and excellent surface finishes at high speeds.

Cost Effective

Lower machining costs due to high speeds, long tool life, and minimal scrap. Ideal for high-volume production.

Superior Finish

Achieves mirror-like surface finishes with minimal effort. Excellent for decorative and plumbing applications.

Good Corrosion Resistance

Moderate corrosion resistance suitable for indoor applications, plumbing, and non-marine environments.
