Executive Summary: As Portugal positions itself as a European hub for renewable energy, electric vehicle (EV) infrastructure, and aerospace innovation (particularly around Porto and Lisbon), the demand for materials that bridge the gap between high conductivity and superior machinability has reached a critical inflection point. Sichuan Kepai New Material Co., Ltd., a leader in high-performance copper alloys, provides the Portugal market with a technological edge through our specialized C14500 and OFT (Oxygen-Free Tellurium) copper solutions.
Portugal’s "Plano de Recuperação e Resiliência" (Recovery and Resilience Plan) highlights a heavy investment in the "Green Transition." This macro-economic shift requires high-efficiency electrical components for solar inverters, offshore wind farms, and the expanding EV charging network. Tellurium Copper (TeCu) is the backbone of these applications. Unlike standard pure copper, which is notoriously difficult to machine, or free-cutting brass, which lacks sufficient conductivity, our Tellurium Copper offers a 85% IACS conductivity rating while maintaining a machinability rating of 85% relative to free-cutting brass.
Traditional C14500 contains trace amounts of oxygen, which can lead to Hydrogen Embrittlement when brazed or welded in hydrogen-rich atmospheres—a common challenge in Portugal's emerging hydrogen economy. Kepai New Material has pioneered the OFT (Oxygen-Free Tellurium) technology. By eliminating oxygen content (<10ppm), we ensure that the tellurium copper remains ductile and structurally sound during high-temperature processing.
In the current global industrial climate, supply chain security is as vital as material quality. Our production facility in Sichuan, covering over 29,000 m², utilizes advanced vacuum induction melting and continuous casting. For our Portuguese partners, this means a reliable "Factory-to-Lisbon" logistics route, backed by ISO 9001:2015 and IATF 16949 certifications, ensuring every batch meets the stringent requirements of the European Union’s REACH and RoHS directives.
We understand that Portuguese manufacturers operate within the strict framework of EU standards. Our Tellurium Copper products are fully compliant with:
Ensuring that our rods and profiles meet the European standard for free-machining copper alloys.
On-site or remote engineering support for Portuguese CNC workshops to optimize cutting speeds and feeds for TeCu.
Streamlined shipping to Porto and Lisbon ports with full documentation support for Portuguese customs (DAP/DDP terms available).
Established in May 2017, Sichuan Kepai New Materials Co., Ltd. is a high-tech enterprise specializing in R&D, production, and sales of high-conductivity, high-strength, free-cutting tellurium copper and other specialized copper alloys. Our mission is to provide the "Gold Standard" of conductive materials for the next generation of global industry.
With an independent R&D team and over 30 patent certificates, we participate in the formulation of industry standards. Our breakthrough in "Highly Conductive Oxygen-Free Tellurium Copper" has redefined performance expectations for high-end plasma cutting and medical connectors.
As a global supplier, we focus on green production. Our free-cutting alloys are designed to be environmentally friendly, aligning with Portugal's sustainability goals and the global push for carbon neutrality.
While C11000 has 100% IACS conductivity, it is "gummy" and extremely difficult to machine, leading to high tool breakage and slow cycle times in Portuguese CNC shops. C14500 (TeCu) offers 85-93% IACS conductivity but increases machining speed by up to 4 times, significantly reducing the cost per part for high-volume connectors.
Every shipment undergoes rigorous testing, including spectral analysis, conductivity testing (IACS), hardness testing, and ultrasonic flaw detection. We provide a full 3.1 Material Certificate with every batch.
Yes, copper alloys have natural antimicrobial and anti-fouling properties. When treated correctly, TeCu offers excellent resistance to atmospheric and marine corrosion, making it ideal for Portugal’s offshore engineering sectors.
Absolutely. We offer customized rods, wires, plates, and tubes with precise diameter and length tolerances to minimize material waste during CNC machining.
