Providing high-conductivity C14500 tellurium copper to Saigon High-Tech Park and local electronics assembly hubs, engineered for high-efficiency auto-lathe operations.
As the economic engine of Vietnam, Ho Chi Minh City (HCMC), along with its adjacent industrial corridors in Binh Duong and Dong Nai, is undergoing a seismic shift from assembly-based manufacturing to high-tech, precision engineering. Anchored by the Saigon Hi-Tech Park (SHTP), the city has attracted global semiconductor giants, consumer electronics pioneers, and automotive parts suppliers. This technological migration has fundamentally increased demand for advanced industrial raw materials.
High-performance alloy systems, particularly Tellurium Copper (ASTM C14500 / UNS C14500), are crucial to supporting this upgrade. Traditional pure copper poses severe challenges during rapid CNC machining due to its ductility, resulting in heavy tool wear and poor edge finishes. Tellurium copper, with its trace addition of tellurium, offers free-cutting characteristics (85% machinability rating) while retaining up to 98% of electrical conductivity. It serves as the backbone for HCMC's high-speed machining centers manufacturing electronic connectors, plasma cutting nozzles, and EV battery terminals.
Sichuan Kepai New Material Co., Ltd. has established robust supply pipelines to support HCMC's growing industrial sector. We provide direct export access, comprehensive metallurgical documentation, and on-demand engineering assistance tailored to Vietnam's high-precision industries.
Understanding the balance between electric conductivity, machinability, and mechanical integrity in C14500 Tellurium Copper systems.
Composed of 0.4% to 0.7% Tellurium, 0.004% to 0.012% Phosphorus, and remaining pure Copper. The addition of Tellurium creates dispersed copper-telluride particles that act as chip breakers, dramatically enhancing chip formation and clearing during CNC milling.
Widely utilized in manufacturing high-current electrical contacts, plasma welding tips, semiconductor packaging heat sinks, sensor housings, and hydrogen energy plumbing. Designed to perform under high temperatures without loss of physical shape.
Next-generation alloys focus on trace element optimization to further enhance tensile strength and wear resistance, while maintaining high conductivity. Kepai is developing sub-micron dispersion alloys and lead-free copper solutions to meet incoming EU & ASEAN eco-requirements.
Established in 2017, Sichuan Kepai New Materials Co., Ltd. is a modern, high-tech enterprise dedicated to the research, development, production, and sales of high-performance copper alloys. Operating from the western area of the Sichuan Guanghan Industrial Development Zone adjacent to National Highway 108, our facilities enjoy streamlined logistical connections to coastal shipping gateways, enabling rapid export services to the port of Ho Chi Minh City.
Our production focus centers on strategic emerging new materials key to national modernization frameworks. We specialize in special copper alloys, including tellurium copper, high-conductivity oxygen-free copper, silver copper, and dispersion-strengthened copper. These materials serve high-precision applications in new energy vehicles (NEVs), 5G telecommunications infrastructure, high-power industrial laser systems, and advanced lithium battery relays.
Under the operating philosophy of "innovation-driven development, quality wins the market," Kepai integrates green manufacturing processes throughout our production lifecycle. We utilize induction melting techniques and closed-loop scrap recycling systems to minimize carbon emissions per ton of alloy produced.

Our tellurium copper conforms fully to ASTM B301/B301M (Standard Specification for Free-Cutting Copper Rod, Bar, and Shapes) and international equivalents like BS EN 12164. Each shipment is accompanied by an official Material Test Report (MTR) verifying chemical composition, electrical conductivity (IACS), tensile strength, and hardness.
Sichuan Kepai leverages intermodal transport routes. Products are routed via overland rail and express highways to major ports (such as Shenzhen, Guangzhou, or Shanghai) and loaded onto direct ocean freight runs arriving at Cat Lai Port in Ho Chi Minh City. Total transit time averages 10 to 14 days post-production.
Yes. Tellurium copper contains microscopic telluride phases that act as chip breakers, changing the continuous ribbons of pure copper into small, brittle chips. This lowers cutting friction, reduces heat generation at the tool tip, and extends carbide insert life by up to 300% compared to C11000 copper.
Yes, products exported from China to Vietnam qualify under the ASEAN-China Free Trade Area (ACFTA). We provide a Certificate of Origin (Form E) with all shipments, enabling Vietnamese importers to secure preferential zero or near-zero import tariff rates, depending on local HS-code declarations.
C14500 has excellent solderability. It exhibits good compatibility with lead-free solder profiles and maintains high joint integrity, making it suitable for automotive wiring harness relays and electrical switchgear assemblies.
