Technical DetailsChittagong (Chattogram), the main maritime gateway of Bangladesh, handles over 90% of the nation's import-export trade. It has evolved from a historic port city into a heavy industrial superpower. The region hosts the massive Mirsarai Economic Zone (Bangabandhu Sheikh Mujib Shilpa Nagar) and multiple steel mills, shipyards, and chemical plants. Consequently, the local demand for advanced non-ferrous alloys is rising quickly.
Heavy steel fabrication, shipbuilding, and maritime dry docks along the Karnaphuli River operate under severe corrosive marine environments. They require materials with excellent mechanical strength, corrosion resistance, and high conductivity. Traditional pure copper often lacks the hardness to withstand mechanical wear, while standard brasses fail under high-temperature welding applications.
This is where Beryllium Cobalt Copper (primarily C17500 / C17510) becomes essential. Combining high electrical conductivity (up to 60% IACS) with tensile strength exceeding 700 MPa, this alloy is key for resistance welding electrodes, marine electrical components, and heavy-duty switchgear. As Bangladesh modernizes its national power grid and expands ship-recycling facilities into modern steel mills, sourcing high-end alloys from trusted global manufacturers is vital for Chittagong's industrial growth.
Established in May 2017, Sichuan Kepai New Materials Co., Ltd. is a high-tech manufacturer specializing in the R&D, production, and sales of high-conductivity, high-strength tellurium copper and other special copper alloys.
Operating from our 29,000 square meter facility, Kepai delivers advanced materials to solve tough industrial challenges. By maintaining a complete production loop—from raw material smelting and horizontal continuous casting to wire drawing, extrusion, and precision testing—we ensure absolute purity and consistency in every batch shipped to Chittagong.
We utilize a protective atmosphere smelting process to keep oxygen levels below 10ppm. This prevents hydrogen embrittlement during subsequent fabrication or welding.
With over 30 patent certificates, our research team continues to develop high-end alloys that push the limits of conductivity, hardness, and thermal resistance.
Why modern engineering projects are shifting from standard copper suppliers to highly integrated Chinese alloy facilities.
Unlike Western toll processors that fragment smelting, extrusion, and drawing, Chinese manufacturers keep all production stages in-house. This lowers energy losses and ensures structural integrity.
We perform systematic testing for chemical composition, electrical conductivity, hardness, and internal flaws using optical emission spectrometers and ultrasonic detectors.
We offer direct shipping from main Chinese ports to Chittagong. With a standard transit window of 15 to 20 days, we prevent project delays for local industrial yards.
