Explore our primary high-performance free-machining copper alloys specifically refined for precision electrical contact, plasma nozzle, and high-current connectors in the Samara Oblast industrial corridor.
The Samara Oblast represents one of Eurasia’s most sophisticated industrial powerhouses. Anchored by major aerospace engineering complexes, rocket engine manufacturing, defense technology clusters, and automotive powerhouses along the Volga river region, Samara demands non-ferrous raw materials that satisfy rigorous thermal, electrical, and mechanical criteria.
As Samara’s advanced machinery manufacturers modernize production lines to meet high-velocity automated standards, conventional Pure ETP (Electrolytic Tough Pitch) copper poses significant challenges. Standard copper causes severe tool wear, long gummy chips, and thermal deformation during high-speed CNC turning and swiss-machining. This has driven rapid demand across Samara for high-conductivity C14500 Tellurium Copper (CuTe).
Metallurgical Superiority: By introducing a controlled 0.4% to 0.7% Tellurium addition to oxygen-free copper, microscopic copper telluride ($Cu_2Te$) phase precipitates form throughout the matrix. These act as intrinsic chip breakers.
Machinability Rating: Yields an 85% rating compared to free-cutting brass (100%), whereas pure copper sits at a sluggish 20%. Crucially, it maintains up to 93-98% IACS electrical conductivity and exceptional thermal dissipation.

Operating from our Guanghan Industrial Development Zone facility, Sichuan Kepai leverages closed-loop digital monitoring throughout the smelting, upward continuous casting, hydraulic extrusion, and cold drawing phases. By utilizing online eddy current testing and automatic optical dimension gauge checks, every batch of tellurium copper rod, wire, and tube strictly conforms to zero-defect mandates.
Our Industry 4.0 setup guarantees tight dimensional tolerance (up to h7/h8 for precision swiss lathe feed stock) and eliminates microscopic voids or inclusions that cause tip blowout during high-power plasma cutter operations in Samara factories.
We understand the imperative of seamless raw material availability for Samara’s manufacturing schedules. Sichuan Kepai has integrated direct rail-freight linkages (China-Europe / Eurasia Rail Network) connecting Western Sichuan logistics hubs directly through to Samara freight terminals.
This logistical resilience safeguards enterprise clients against maritime disruptions, delivering predictable lead times, customized export packaging, anti-corrosion VCI wrapping, and complete customs compliance documentation for Eurasian customs clearance.
Our fully equipped laboratory and production floor guarantee that all chemical compositions, grain structures, and mechanical parameters conform strictly to ASTM B301, EN 12164, and equivalent international standards.
Samara is globally recognized for rocket technology and aerospace assembly. C14500 Tellurium Copper provides unmatched reliability for electrical connectors, signal sockets, and high-frequency power terminals operating under severe vibration and thermal fluctuations.
Heavy industrial machining units in Samara require plasma cutting nozzles and contact tips that resist thermal erosion and spatter adhesion. Kepai’s Oxygen-Free Tellurium Copper (OFT) extends nozzle service life by up to 35% compared to ETP copper.
With the shift toward electric transportation and smart grid infrastructure, high-current DC relays require non-welding contact pins. Tellurium copper’s superior arc resistance and thermal dissipation prevent contact oxidation and latching failures.
Adhering strictly to ISO9001 quality management, environmental standards, and international material specifications (ASTM, EN, DIN, GOST compliant).
Comprehensive range of high-conductivity oxygen-free copper, beryllium copper, and specialty alloys engineered for international industry demand.
Looking ahead, Sichuan Kepai New Materials Co., Ltd. will continue to uphold its original intention, with even greater enthusiasm and determination, to engage in research and application in the field of new materials, contributing to the development of the new copper alloy materials industry in China and globally. We look forward to working hand in hand with friends from all walks of life to create a brilliant future together!
