As Indonesia's primary economic engine, Jakarta and its surrounding industrial satellite cities (Cikarang, Karawang, and Bekasi) are undergoing a monumental shift toward high-tech manufacturing, renewable energy, and electric vehicle (EV) infrastructure. At the heart of this transformation lies the demand for High-Performance Copper Alloys, specifically Tellurium Copper (C14500).
The Greater Jakarta region is home to the most significant concentration of automotive assemblers and electronics manufacturers in Southeast Asia. With the Indonesian government's push for the "Making Indonesia 4.0" initiative, factories are upgrading their precision machining capabilities. Standard copper often falls short in modern high-speed CNC environments due to its low machinability rating. Our Tellurium Copper provides the solution, offering a machinability rating of 85% compared to pure copper's 20%, significantly reducing tool wear and production costs for Jakarta-based precision engineering firms.
With the rise of the Indonesian EV battery ecosystem, the demand for components with high electrical and thermal conductivity—such as connectors, switchgears, and battery terminals—is skyrocketing. Tellurium Copper maintains 93-96% IACS conductivity, making it the ideal material for high-current applications where heat dissipation is critical. Our export logistics to the Port of Tanjung Priok ensure that Jakarta’s supply chain remains robust and just-in-time.

Sichuan Kepai New Materials Co., Ltd. is a high-tech pioneer specializing in high conductivity and high strength free-cutting tellurium copper. Since 2017, we have bridge the gap between material science and industrial application.
In the global market, procurement teams are no longer just looking for a "supplier"—they are looking for a partner who can provide Information Gain. Our R&D team continuously evolves our technical roadmap to address emerging challenges in miniaturization and power density.
We are currently developing Oxygen-Free Tellurium Copper (OFT) which combines the hydrogen embrittlement resistance of oxygen-free copper with the machinability of tellurium copper. This is set to redefine the standard for vacuum electronics and high-end power transmission.
Supplying high-purity copper components for MRI and diagnostic machinery in Jakarta’s healthcare expansion.
High-conductivity connectors for EV charging stations and battery management systems.
Critical conductive parts for ground support and generator systems at Soekarno-Hatta International Airport infrastructure.
Navigating the Indonesian market requires strict adherence to international and local standards. Kepai New Material ensures that every shipment to Jakarta is accompanied by:
Standard copper is "gummy" and clogs CNC tools. C14500 Tellurium Copper produces short, clean chips, allowing for higher spindle speeds and extended tool life, often reducing part cost by 30-50% in high-volume production.
Yes, we offer custom rods, plates, and wires tailored to specific tolerances required by your engineering drawings. We specialize in non-standard diameters for heavy-duty connectors.
We use high-purity electrolytic copper as the base material and strictly control the tellurium content (0.4% - 0.7%) and oxygen levels during our proprietary smelting process.
For standard specifications, we maintain a large stock. Shipping from our facility to the Port of Tanjung Priok typically takes 10-15 days via sea freight, with air freight options available for urgent prototypes.
