Top-tier copper alloys optimized for Australian mining, energy, and precision engineering sectors.
Australia's industrial sector is undergoing a massive transformation, driven by the "Critical Minerals Strategy" and a nationwide shift toward renewable energy. Sulfur Copper (C14700), known for its exceptional machinability (85% of free-cutting brass) and high electrical conductivity (minimum 90% IACS), has become a cornerstone material for Australian manufacturers. From the bustling tech hubs in Sydney and Melbourne to the remote mining sites in Western Australia's Pilbara region, the demand for alloys that can withstand high temperatures while maintaining electrical integrity is at an all-time high.
As a leading Sulfur Copper manufacturer serving Australia, we recognize the unique challenges posed by the "Down Under" climate and regulatory environment. Our materials are engineered to exceed AS/NZS standards, ensuring that components used in solar inverters, EV charging stations, and deep-sea mining equipment perform flawlessly in corrosive and high-heat environments.

Globally, the copper alloy market is shifting away from leaded alloys due to environmental restrictions like REACH and RoHS. Sulfur Copper serves as the "green" alternative to leaded brass in many high-precision electrical applications. In Australia, where environmental sustainability is a core pillar of the manufacturing sector, adopting C14700 is not just a technical choice but a compliance necessity.
Our macro-level strategy involves a dual-track approach: providing high-volume standardized bars and plates for large-scale energy projects while maintaining a boutique "Custom Shop" for Australian startups specializing in aerospace and medical devices. This flexibility allows us to bridge the gap between global supply chain efficiency and localized Australian service requirements.
Driving the next generation of high-performance copper materials through AI-assisted metallurgical research.
Our oxygen-free sulfur copper alloys utilize independent intellectual property. We leverage AI-driven simulation to optimize grain structure, ensuring consistent tool life for Australian CNC shops.
We provide full documentation for ISO 9001:2015 and IATF 16949 standards, tailored to meet Australian WHS (Work Health and Safety) and environmental regulations.
Transitioning toward "Zero-Waste" manufacturing. We are currently developing ultra-high-purity tellurium and sulfur copper blends for the quantum computing sector emerging in Brisbane.
Established in May 2017, Sichuan Kepai New Materials Co., Ltd. is a high-tech private company specializing in R&D, production and sales of high conductivity and high strength free cutting tellurium copper, sulfur copper, and other special copper alloys. Our factory floor space spans 29,000 sqm, providing the scale needed to support massive Australian infrastructure projects.

How our sulfur copper is powering Australia's key industries.
While both are free-cutting, C14700 Sulfur Copper typically offers a slightly better cost-to-performance ratio for applications where extreme thermal resistance isn't the primary factor but high-speed machinability and high electrical conductivity (90% IACS) are paramount.
Yes. We understand that Australian OEMs often require precision prototyping. We offer customized bar diameters and plate thicknesses, with logistics support directly to ports in Perth, Adelaide, Brisbane, and Sydney.
Our Sulfur Copper is produced with a strictly controlled oxygen-free process, which significantly reduces the risk of hydrogen embrittlement and surface oxidation compared to standard grade coppers, making it ideal for coastal infrastructure.
Standard stock items can be dispatched within 48 hours. For custom industrial runs, our typical lead time to Australian ports is 3-5 weeks, including all necessary compliance documentation.
A comprehensive range of high-performance alloys ready for dispatch.
We customize alloys to match any Australian industrial requirement.
