In the rapidly evolving landscape of high-speed manufacturing and power electronics, C14500 Tellurium Copper (TeCu) has emerged as a cornerstone material. Unlike traditional pure copper, which presents significant challenges in high-precision machining, C14500 is specifically engineered to provide a perfect balance between high electrical conductivity (90-96% IACS) and exceptional machinability.
As a leading Custom C14500 Tellurium Copper Bar exporter, Sichuan Kepai New Materials Co., Ltd. (KEPAI) leverages cutting-edge precipitation hardening and oxygen-free casting technologies to deliver bars that meet the stringent requirements of the aerospace, electric vehicle (EV), and semiconductor industries.

E-E-A-T Insight: Understanding the Shift in Copper Alloy Demand
The transition to 800V EV architectures requires connectors and charging pins with superior thermal dissipation and high current carrying capacity, making C14500 the material of choice.
Precision RF connectors demand materials that can be machined into complex geometries without losing signal integrity or electrical efficiency.
The move toward "Green Copper" means reducing waste. Our oxygen-free tellurium copper minimizes oxidation during high-temperature processing.
Automated CNC lines require consistent material hardness. Kepai's bars ensure extended tool life and zero-defect production runs.
For global procurement managers and design engineers, sourcing C14500 isn't just about the raw material; it's about a comprehensive macro-solution that addresses supply chain resilience and technical compliance. At KEPAI, we offer:
The Next Generation of Tellurium Copper Alloys (2025-2030)
Moving beyond standard C14500 to Oxygen-Free Tellurium (OFT) copper, which eliminates hydrogen embrittlement risks during brazing and welding.
Incorporating trace elements to enhance the softening temperature, allowing copper bars to maintain strength in extreme thermal environments up to 450°C.
Implementing IoT sensors in our extrusion lines to provide customers with "Digital Material Passports" for every batch of C14500 copper bars.
Navigating international trade requires more than just high-quality products. As a trusted tellurium copper exporter, KEPAI adheres to the highest global standards:
Our materials are fully compliant with RoHS 3.0 and REACH, ensuring they can be used in electronic products sold in the EU and North American markets without legal friction.
We are certified under ISO 9001:2015, ISO 14001:2015, and IATF 16949 (the gold standard for automotive supply chains).
Non-magnetic properties and bactericidal effects for MRI components and surgical instruments.
High-current DC contactors and charging infrastructure requiring rapid thermal dissipation.
Reliable data transmission parts and generators operating under extreme atmospheric pressures.
Resistance to seawater corrosion and fouling for underwater sensors and power connectors.
C11000 (Pure Copper) is extremely gummy during machining, leading to tool wear and poor surface finish. C14500 contains 0.4-0.7% tellurium, which acts as a "chip breaker," increasing the machinability rating to 85% compared to 20% for pure copper.
While alloying usually reduces conductivity, tellurium is unique. C14500 maintains a high conductivity of minimum 93% IACS, making it the best choice when both precision and power efficiency are required.
Yes, C14500 has excellent hot workability and good cold workability. This versatility allows manufacturers to produce complex forged shapes before final precision machining.
Absolutely. We use advanced recycling and filtration systems in our Sichuan factory. Our materials are fully compliant with RoHS standards, ensuring zero lead-contamination in our TeCu alloys.
