Engineering Excellence
Why C36000 Free-Cutting Brass Dominates Precision Machining
Known as the global benchmark for high-speed brass machining, UNS C36000 is alloyed with precise lead content to provide optimal chip clearance, rapid cycle times, and excellent tool preservation under tight tolerances.
100% Machinability
Provides clean, predictable chip fracture during high-RPM turning, allowing accelerated feed rates, lower spindle load, and extended tool cutting life.
Dimensional Stability
Exceptional stress relief characteristics ensure low distortion in thin-walled shells, micro-bore channels, and micro-pitch connector threading.
Corrosion Resistance
Proven durability against non-oxidizing acids, water exposure, and standard industrial chemicals, making it ideal for fluid lines and gas regulators.
Surface Plating Affinity
Smooth turned finishes require minimal pre-treatment, bonding securely with electroplated nickel, chrome, tin, silver, or gold coatings.
