In the era of rapid electrification, the demand for materials that exhibit Excellent electrical and thermal conductivity has transitioned from a specialized requirement to a global industrial necessity. Sichuan Kepai New Materials Co., Ltd. (Established 2017) stands at the forefront of this evolution, merging advanced metallurgy with precision manufacturing.
Traditional copper offers high conductivity but poor machinability. Our Oxygen-Free Tellurium Copper (OFT) provides the "Holy Grail" of materials: 98% IACS conductivity combined with superior free-cutting performance. This innovation significantly reduces tool wear and energy consumption during CNC processing.
For aerospace and precision connectors, our C17200 and C17300 alloys deliver the highest strength of all copper-based materials. We utilize precipitation hardening to reach ultimate tensile strengths exceeding 200 ksi while maintaining reliable thermal pathways.
Whether it's marine engineering with corrosion-resistant alloys or medical equipment requiring antimicrobial properties, Kepai materials are tested under rigorous stress-corrosion and high-cycle fatigue parameters.
Strategic applications where Kepai materials define competitive advantage.
High-conductivity Tellurium Copper is essential for charging piles, high-voltage connectors, and battery busbars. As EV architectures move toward 800V and above, thermal management becomes critical. Our alloys ensure minimal heat generation and maximum charging efficiency.
In satellite communications and generator systems, weight-to-performance ratios matter. Our C19160 high-strength alloys provide the durability needed for extreme vibration environments while ensuring lossless signal transmission.
From MRI components to surgical instruments, copper's natural antimicrobial properties combined with our precision alloying techniques provide safe, reliable, and high-performance components for life-saving technologies.
Expansion of our Oxygen-Free High Conductivity (OFHC) Tellurium series. Aiming to achieve >99.5% IACS for high-frequency 5G/6G applications where skin effect losses must be minimized.
R&D focus on grain refinement and nanotechnology to enhance the fatigue life of spring contacts in micro-electronics without compromising thermal dissipation rates.
Implementing a full closed-loop recycling system for high-purity copper scrap, reducing the carbon footprint of "Excellent Conductivity" materials by 40% to meet global ESG requirements.
Integrating intelligence into every stage of production.
Our autonomous vacuum melting and continuous casting lines ensure zero impurity contamination, vital for maintaining high thermal conductivity.
Strategically located in Sichuan, we leverage China's robust logistics to export to over 50 countries with lead times 30% faster than the industry average.
Real-time eddy current testing and spectral analysis ensure every batch of C14500 or C17200 meets exact chemical and physical specifications.
All Kepai materials comply with RoHS, REACH, and Conflict Minerals regulations. We hold ISO9001:2015, ISO14001:2015, and OHSAS 45001:2018 certifications.
We provide Vendor Managed Inventory (VMI) and Just-In-Time (JIT) delivery for Tier-1 automotive and electronics manufacturers, ensuring no production downtime.
Our experts assist in material selection based on your specific FEA (Finite Element Analysis) thermal models to optimize your component's performance.
Our TeCu alloys achieve a machinability rating of 85% compared to pure copper. This is due to the uniform distribution of telluride particles, which act as chip-breakers, allowing for higher feed rates and longer tool life while maintaining 98% conductivity.
Yes, we offer everything from high-elastic C17200 beryllium copper foils to heavy-duty lead bronze castings. Our production flexibility allows for custom thickness, width, and temper states (Half-Hard, Full-Hard, Annealed).
Every batch undergoes thermal diffusivity testing. For high-conductivity applications, we ensure the absence of phosphorus deoxidizers which can severely degrade thermal performance if not controlled.
While we are a high-volume exporter, we provide a dedicated R&D line for prototyping innovative "Excellent Conductivity" solutions to help our clients through the R&D and validation stages.
