Get QuoteAs the industrial capital of Mexico, the Monterrey metropolitan area (Nuevo León) has evolved into the preeminent hub for manufacturing nearshoring in North America. Driven by massive investments in automotive electrification, aerospace tooling, consumer electronics, and heavy-duty machinery, the demand for precision raw materials has reached unprecedented heights.
Sulfur Copper (UNS C14700) acts as a key material in this manufacturing evolution. Unlike standard pure copper (C11000), which is notoriously difficult to machine due to its gummy nature, sulfur copper introduces a precise micro-addition of sulfur (0.2% to 0.7%). This results in a machinability index of 85% (compared to C11000's 20%), enabling Monterrey-based Tier-1 and Tier-2 manufacturers to run CNC machining centers at maximum spindle speeds without premature tool wear or burr generation.
Furthermore, with the relocation of advanced automotive plants and charging infrastructure component suppliers to Monterrey, materials must deliver both structural integrity and extreme electrical conductivity (retaining 90-95% IACS).四川 Kepai New Materials Co., Ltd. fills this technical gap by exporting optimized sulfur copper and tellurium copper alloys that align with strict ASTM, EN, and JIS standards.
Using C14700 and C14500 alloys cuts down machining cycle times by up to 40% compared to pure copper, while drastically reducing scrap rates and eliminating thermal distortion during dry machining phases.
Established in 2017, Sichuan Kepai New Materials Co., Ltd. is a high-tech enterprise integrating research, development, production, and sales. Currently, our factory covers an area of approximately 9,000 square meters, complemented by an office space of about 1,000 square meters. We primarily focus on the manufacturing of strategic emerging new materials, including special copper alloys such as tellurium copper, sulfur copper, high-conductivity oxygen-free copper, silver copper, and dispersion copper.
Our primary operational objective is the research and development of high-conductivity, easy-to-machine, high-strength copper alloys. The resulting products are mainly applied in high-tech fields such as new energy vehicles, 5G communications technology, industrial laser cutting systems, and high-voltage lithium battery relays. Situated in the western area of the Sichuan Guanghan Industrial Development Zone, adjacent to National Highway 108, our facility benefits from convenient logistics access to major shipping ports, securing a reliable supply chain for clients across North America, including Monterrey.
"Innovation-driven development, quality wins the market. We are committed to providing the highest quality high-end copper alloy materials, promoting global industrial upgrading and sustainable development."

Technological innovation is the core competitiveness of Sichuan Kepai New Materials Co., Ltd. Our engineering team consists of senior metallurgical experts who closely monitor international material science trends and push the envelope in copper alloy optimization. Through a combination of independent research and collaboration with key research institutions, Kepai has achieved significant technical milestones in high-performance tellurium copper, lead copper, and sulfur copper.
Many of our proprietary technological formulations meet international standards and are successfully used in new energy vehicles, precision CNC machining, plasma cutting, relays, and power grid infrastructure. Our rich product system covers everything from basic alloys to complex, custom metallurgical profiles designed to reduce processing costs and enhance the operating lifetimes of client hardware.
As global manufacturers seek to diversify and fortify their material sourcing pipelines, Sichuan Kepai provides a reliable combination of industrial capacity, strict chemical quality control, and cost advantages. By deploying advanced manufacturing processes under Industry 4.0 guidelines, we ensure that every batch of sulfur copper exported to Mexico exhibits uniform grain structures and tight dimensional tolerances.
Our facility uses computerized oxygen-free induction melting furnaces coupled with automatic draw systems. This keeps oxygen levels below 10ppm, preventing hydrogen embrittlement and maintaining high conductivity.
Every shipment of sulfur copper C14700 or tellurium copper C14500 is accompanied by detailed Mill Test Certificates (MTC) showing exact chemical compositions (S, P, Cu ratios), hardness values, and electrical conductivity metrics (IACS%).
With structured export processes and established freight partnerships, we coordinate seamless maritime and inland shipping routes to Monterrey’s primary industrial parks (including Apodaca, Santa Catarina, and Guadalupe).
How are our premium copper alloys being deployed within Monterrey's local manufacturing clusters? Below are the key engineering applications driving nearshore procurement:
Automotive wiring harness and connector manufacturers use C14700 sulfur copper for its combination of high electrical conductivity and clean thread-cutting capability on automatic Swiss-type screw machines.
With Monterrey being a hub for heavy steel fabrication and machinery production, fabricators rely on plasma cutting nozzles made of tellurium copper (C14500) and sulfur copper for optimal arc stability and thermal dissipation.
Industrial grid infrastructure demands components that can withstand high electrical loads without overheating. Free-machining copper alloys allow for the cost-effective production of heavy-duty switchgear terminals.
Sichuan Kepai operates in strict accordance with international quality assurance systems. Our products undergo comprehensive testing protocols to ensure compliance with global environmental and technical standards.
From raw material smelting to final dimensional calibration and package sealing, our factory operates advanced production lines and material analysis equipment to guarantee the performance of our copper alloys.

Both alloys are designed for high-speed CNC machining with excellent electrical conductivity. C14700 (Sulfur Copper) features a micro-addition of sulfur, providing a machinability rating of 85% and maintaining around 90-93% IACS conductivity. C14500 (Tellurium Copper) uses tellurium, offering similar machinability (85%) but typically exhibiting slightly higher conductivity (up to 95-98% IACS) and better hot workability. In terms of cost, sulfur copper is often more economical for high-volume automated screw machining applications.
We employ a closed-loop quality control system under ISO 9001:2015. Raw cathode copper is melted in induction furnaces with precise monitoring of oxygen levels. Additives are calculated and introduced via computer-controlled feeders. Every batch undergoes chemical composition verification via optical emission spectrometry, and physical inspection utilizing eddy current testers and universal tensile machines to confirm mechanical and electrical parameters.
For standard alloy shapes (rods, wires, sheets), our typical production lead time is 15-25 days from order confirmation. Shipments are packed in sea-worthy export crates to prevent moisture exposure and surface oxidation. Maritime transit to Mexican ports (such as Manzanillo or Altamira) followed by inland transport to Monterrey takes approximately 25-35 days, providing a predictable supply chain for Mexican buyers.
