C360 Free-Cutting Brass CNC Machining & Turning Specs

C360 Free-Cutting Brass is the global benchmark for 100% machinability rating, allowing extreme cutting speeds, superb tool longevity, and mirror-like surface finishes.

Engineering Specifications & Parameters

Density 8.50 g/cm³
Cutting Speed 200 - 600 m/min
Yield Strength 310 MPa (45,000 psi)
Machinability Rating 100% (Standard Benchmark)

Machining Advantage

C360 contains trace lead that acts as a microscopic chip breaker and internal lubricant, resulting in tiny, brittle chips and zero tool build-up.

Best Practices

  • Spindle Speed: High RPM (up to machine limits).
  • Surface Finish: Readily achieves Ra 0.4 μm or better straight off the tool.

Frequently Asked Questions

Why is C360 brass considered the machinability standard?

All other engineering metals are indexed against C360 (100%) due to its optimal balance of fast chip evacuation and minimal cutting force.
