In the evolving landscape of advanced manufacturing, the search for high-performance, free-machining copper alloys has led engineers to prioritize C14700 Sulfur Copper. As a global exporter, Sichuan Kepai New Materials Co., Ltd. has positioned itself at the forefront of this niche, providing critical materials for sectors ranging from EV charging infrastructure to high-speed electrical connectors.
Unlike traditional Tellurium Copper (C14500), which relies on Tellurium for machinability, C14700 utilizes sulfur to create a free-machining copper alloy. This offers an unparalleled cost-to-performance ratio. With an electrical conductivity reaching 90-95% IACS, it maintains the integrity of pure copper while significantly reducing the cycle times for CNC precision machining. This "information gain" is vital for procurement managers: choosing C14700 often reduces tool wear and increases throughput in mass production environments.
The global industrial supply chain has shifted its focus to China due to the manufacturing efficiency integrated into the production cycle. At Kepai, our 9,000 sqm facility isn't just about output; it's about technological optimization. By integrating smelting, extrusion, and drawing processes under one roof, we minimize material loss and energy consumption. This allows us to provide wholesale C14700 at price points that remain competitive while adhering to stringent international quality standards (ASTM/ISO).
Optimized microstructure ensuring 90%+ conductivity for sensitive electronic components.
Designed for high-speed CNC turning, minimizing burr formation and tool friction.
From 2017 to present, we have mastered complex alloy formulations for the 5G and EV sectors.
Proven track record of supplying internationally renowned industrial enterprises.
The transition to New Energy Vehicles (NEVs) and the expansion of 5G infrastructure have created a surge in demand for materials that handle high thermal loads without compromising conductivity. C14700 is currently seeing unprecedented adoption in:
Kepai’s investment in metallographic testing machines and electronic universal testing machines ensures that every batch of C14700 meets these evolving rigorous standards.
A: While both are free-machining, C14700 (Sulfur Copper) is often more cost-effective for large-volume production while offering comparable conductivity and machinability characteristics. It is the ideal economic choice for mass-produced electrical hardware.
A: We utilize advanced Eddy Current Conductance instruments and chemical composition testing labs for every batch. Our quality control covers the entire lifecycle from smelting to final packaging.
A: Yes. As a tech-driven manufacturer, our R&D team works closely with clients to tailor metallurgical properties, including custom sizes and hardness levels, to fit specific application requirements.
