As Southeast Asia's largest economy, Indonesia is undergoing a rapid transition toward advanced manufacturing under the "Making Indonesia 4.0" roadmap. Key sectors such as automotive electronics, new energy infrastructure, and precision machinery require raw materials that offer the perfect balance of electrical conductivity and machinability. Sulfur Copper (C14700) has emerged as the critical material of choice for engineers across Jakarta, Bekasi, and Karawang industrial zones.
Unlike standard electrolytic copper, Sulfur Copper is engineered for high-speed machining. In the context of Indonesia's growing component export market, the ability to produce high-tolerance parts with minimal tool wear is a massive competitive advantage. Kepai New Material, as a global leader in high-conductivity alloys, provides the Indonesian market with C14700 grades that exceed traditional standards, ensuring local manufacturers can meet international quality requirements like ASTM B301.
Furthermore, Indonesia's focus on the Electric Vehicle (EV) supply chain has increased the demand for alloys that can withstand high temperatures while maintaining peak conductivity. Sulfur Copper’s unique properties facilitate the production of complex connectors and electrical terminals, which are the nervous system of modern EV battery packs and charging stations.
Our logistics network ensures seamless delivery to major free trade zones, supporting electronics manufacturers in Batam and automotive giants in West Java.
We provide high-quality raw materials that help local Indonesian enterprises optimize their value chain and improve the quality of finished goods for both domestic use and export.
Our engineering team offers virtual and on-site consultancy for Indonesian factories looking to transition from traditional brass to high-efficiency sulfur copper alloys.

Kepai New Material (Sichuan) provides a unique "Information Gain" to our Indonesian partners by sharing our R&D breakthroughs in oxygen-free high-conductivity tellurium and sulfur copper. By manufacturing in China, we leverage a world-class supply chain ecosystem, allowing us to offer pricing that is 15-20% more competitive than Western suppliers without compromising on 99.9% purity standards. Our specialized casting processes reduce internal stresses in the copper, meaning your CNC machines in Indonesia can run 30% faster with lower reject rates.
High-conductivity sulfur copper is essential for the connectors used in the electric buses and passenger cars currently being developed in Indonesia.
Supporting the growing telecommunications sector with high-reliability connectors that ensure minimal signal loss.
Corrosion-resistant copper alloys for Indonesia's vast maritime engineering projects and port developments.
Sulfur Copper contains a small amount of sulfur (approx. 0.20% to 0.50%), which acts as a lubricant during machining. This improves the "Machinability Rating" from 20% (Pure Copper) to 85%, allowing for complex shapes to be milled quickly while retaining 93-96% IACS conductivity.
Yes, we are experienced in exporting to major Indonesian ports. We handle all documentation, including Certificates of Origin and compliance reports, to ensure smooth customs clearance in accordance with Indonesian trade regulations.
Absolutely. All Kepai products undergo rigorous testing to ensure they meet international environmental standards, making them safe for export products destined for Europe or the US from your Indonesian factory.
We provide a wide range of standard diameters and thicknesses, and we can customize dimensions based on your specific production line requirements in Indonesia.
