Explore our industrial-grade, certified copper and brass alloys engineered for deep drawing, electrical systems, and high-performance engineering.
Established in May 2017, Sichuan Kepai New Materials Co., Ltd. is a high-tech private enterprise specializing in the R&D, production, and sales of high-conductivity, high-strength, free-cutting tellurium copper and other specialized copper alloy sheets and profiles. Our engineering paradigm matches the rapid evolution of next-generation power electronics, electric vehicular networks, and complex aerospace systems.
We do not just manufacture materials; we design structural electrical interfaces. Operating from a highly modernized manufacturing plant, Kepai possesses the processing capabilities to deliver pure copper sheets (C11000, C10100) and highly engineered precipitation-hardening copper-beryllium, copper-nickel-silicon, and sulfur copper sheets to tight dimensional tolerances.

A comprehensive overview of our standard and custom copper sheet alloys, structural compositions, and thermal-electrical metrics.
Optimized for heavy duty plasma cutting electrodes and electric switches. Provides a free-machinability rating of 85% with high electrical conductivity (>93% IACS), ensuring superior thermal dissipation under extreme localized currents.
Precipitation-hardened alloys reaching tensile strengths of up to 1380 MPa (200 ksi). Specially rolled into thin high-elastic copper foils and springs designed to resist mechanical fatigue in avionics and micro-connectors.
Refined to 99.99% purity. Features less than 0.001% oxygen content, making it immune to hydrogen embrittlement. Indispensable for semiconductor backing plates, vacuum chambers, and high-frequency busbars.
In high-power industrial applications, copper selection is governed by the trade-off between mechanical yield strength and electrical conductivity (IACS%). Pure copper (C11000 / C10100) yields optimal conductivity but suffers from low tensile strength and poor machinability. Traditional free-cutting brasses introduce lead (Pb) to solve machinability issues, but compromise electrical properties and environmental compliance (under RoHS/REACH directives).
Sichuan Kepai New Materials resolves this dilemma through engineered alloying strategies:
Our processing controls guarantee that each custom copper sheet maintains uniform grain structure, isotropic flatness, and minimal burr formation during laser and mechanical shear processing.
How Kepai's tailored copper sheets and alloys support key industrial sectors globally.
Utilizing high-purity copper's intrinsic antimicrobial properties. Copper plates are formed into sterile touch surfaces, gas pipelines, and shielding components for MRI scanners and diagnostic machinery.
High-conductivity C11000 and C14500 sheets are vital for EV battery busbars, charging socket terminals, inverter junctions, and battery module connectors where low resistance reduces thermal loss.
High-strength beryllium copper alloys supply aerospace actuators, landing gear bushings, and avionic connectors, maintaining structural integrity under extreme vibration and thermal cycles.
Our cupronickel and special bronze sheets resist biofouling and seawater erosion, serving as heat exchanger tube sheets, marine pump components, and desalination infrastructure.
Custom-engineered tellurium copper sheets and rods are machined into premium plasma torches, nozzle tips, and electrode holders, increasing duty cycles and reducing downtime.
Heavy-gauge copper busbars connect grid-scale solar inverter systems and lithium-ion container batteries, facilitating high energy transfer rates with minimal impedance.
How Sichuan Kepai leverages cutting-edge metallurgic processing and localized vertical integration to optimize lead times and cost.
Our factory utilizes horizontal continuous casting systems coupled with precision reversing rolling mills. This setup controls phase distributions of tellurium and phosphor, yielding highly isotropic mechanical properties in both longitudinal and transverse directions.
Located in Sichuan, China, Kepai leverages direct access to high-purity copper cathode and mineral resources. This vertical proximity insulates clients from global raw material price swings and shipping bottlenecks.
We strictly monitor heavy metal traces in accordance with RoHS. Our zero-discharge water cooling systems and regenerative gas furnaces minimize energy consumption, meeting modern global sustainability targets.
Committed to transparency and global quality metrics, we ensure all products comply with rigorous standard specifications.
Operating as a certified OEM/ODM exporter, Sichuan Kepai is certified under ISO 9001:2015 for quality management, ISO 14001:2015 for environmental management, and ISO 45001:2018 for occupational health and safety. Every single shipment is trace-identified with an official Mill Test Certificate (MTC) detailing chemical composition limits (determined via ICP-OES spectrometry), tensile strength (MPa), elongation percentage, and IACS% conductivity values.
We support standard ASTM, EN, JIS, and GB specifications. Whether your design requires custom tolerance ranges, special degreasing, paper-interleaved packing, or specific temper designations (O, H02, H04, or hard-spring tempers), our engineering team executes QA protocols to secure consistency across multiple batch runs.
