In the modern manufacturing landscape, the demand for precision, conductivity, and durability has never been higher. As a High-Quality Lead Brass Manufacturer & Exporter, Sichuan Kepai New Materials Co., Ltd. stands at the intersection of metallurgical tradition and technological innovation. Established in 2017, our journey began with a singular focus: to redefine the standards of tellurium copper and free-cutting copper alloys for the global market.
Lead brass, often referred to as the "King of Machinability," particularly the C36000 alloy, remains an indispensable material in high-speed CNC machining. The addition of lead serves as a micro-lubricant, ensuring small, manageable chips and reducing tool wearβa critical factor for exporters servicing the precision instrument and automotive sectors. However, the industry is evolving. Our R&D team is actively pushing the boundaries of information gain in material science, providing insights into how trace elements like sulfur, tellurium, and beryllium can enhance performance in extreme environments.

The global copper alloy market is currently witnessing a shift towards high-value-added materials. While traditional lead brass maintains its dominance in hardware and plumbing, the aerospace and new energy vehicle (NEV) sectors are demanding alloys with higher thermal stability and electrical conductivity. As a leading exporter, we track these shifts to ensure our supply chain meets the rigorous IATF 16949 standards.
Lead brass manufacturers are no longer just suppliers; we are solution partners. By integrating Oxygen-Free High Conductivity (OFHC) copper with free-cutting elements, we enable manufacturers to produce complex connectors for 5G infrastructure and medical electronics that were previously impossible to machine efficiently.
Sustainability is the new benchmark. The industry is moving towards "Lead-Free" and "Low-Lead" regulations (such as RoHS and REACH). Kepai is at the forefront, developing Sulfur Copper (C14700) as an environmentally friendly alternative that maintains high machinability without the ecological footprint of heavy metals.
Our R&D philosophy is built on "Precision Metallurgy." We don't just melt copper; we engineer atomic structures. Our technical roadmap focuses on three pillars:
High-purity lead brass and copper alloys are vital for MRI components and antimicrobial surfaces in surgical theaters.
Conductivity is the currency of the EV era. Our Tellurium Copper C14500 is the industry standard for high-voltage charging connectors.
Beryllium copper's non-sparking and high-strength properties make it ideal for landing gear bushings and cockpit instrumentation.
Corrosion resistance in seawater is non-negotiable. Our lead bronze alloys power the next generation of desalination and subsea robotics.
To provide true Information Gain to our partners, we must discuss the "Micro-Lead Dispersion" effect. In our high-quality lead brass, lead is not soluble in the copper matrix. Instead, it exists as highly dispersed globules. When a cutting tool hits these globules, they act as an internal lubricant, reducing the coefficient of friction by up to 40%. This is why our C36000 and C54400 alloys allow for 25% higher spindle speeds compared to standard competitors.
Furthermore, our Oxygen-Free High Conductivity (OFHC) tellurium copper (TeCu) undergoes a vacuum casting process that eliminates hydrogen embrittlement. This is a crucial distinction for manufacturers in the plasma cutting industry, where electrode life is directly tied to the absence of oxygen pockets in the raw material.
We provide localized warehousing and just-in-time delivery for global exporters, mitigating the risks of fluctuating LME copper prices.
