In the current global manufacturing landscape, free-cutting brass has transitioned from a basic commodity to a critical strategic material. As Industry 4.0 drives the demand for ultra-high precision components, the metallurgical integrity of brass alloys directly dictates the efficiency of automated production lines. Kepai New Material, established in 2017, stands at the intersection of traditional metallurgy and futuristic material science.
Modern CNC machines operate at spindle speeds exceeding 15,000 RPM. Traditional alloys often fail under such thermal and mechanical stress, leading to tool wear and production downtime. Our proprietary Oxygen-free high conductivity tellurium copper and C36000 Lead Brass are engineered with precise micro-structures that act as internal lubricants, reducing friction by up to 30% compared to standard commercial grades.
Achieving a 100% machinability rating, setting the benchmark for precision turning and Swiss-style machining.
Balancing high mechanical strength with electrical conductivity up to 95% IACS for EV and power applications.
Active R&D in lead-free and low-lead brass alloys to meet stringent RoHS and REACH environmental mandates.
Focus on high conductivity and high strength free cutting tellurium copper and other copper alloys
Established in May 2017, Sichuan Kepai New Materials Co., Ltd. is a high-tech private company specializing in R&D, production and sales of high conductivity and high strength free cutting tellurium copper and other special copper alloys.
