Premium precision materials engineered to handle extreme mechanical and electrical loads.
Bangkok and its surrounding provinces, particularly the key zones within the Eastern Economic Corridor (EEC), have transitioned from traditional manufacturing centers into advanced technological hubs. The acceleration of high-performance automotive platforms, precision consumer electronics, and smart energy infrastructure across Samut Prakan, Chonburi, and Rayong has fueled a surge in demand for specialized copper alloys. High among these is Beryllium Cobalt Copper (C17500 / C17510), which offers a unique combination of high thermal conductivity and superior mechanical strength.
For industries located in Bangkok's metropolitan region, maintaining a continuous supply chain of grade-A alloyed copper is critical. Standard copper variations cannot handle the combined heat and stress of robotic resistance welding lines, automotive wire harnesses, and semiconductor lead frames. Local sub-tier automotive suppliers are increasingly requesting Beryllium Cobalt Copper because of its ability to retain structural integrity at elevated temperatures. It serves as the primary electrode material for spot welding operations, particularly in light-alloy automotive body structures where efficiency and consistency determine profitability.
By micro-alloying copper with 0.4–0.7% Beryllium and 2.4–2.7% Cobalt, the alloy undergoes precipitation hardening. This results in an electrical conductivity rating of up to 60% IACS while maintaining a hardness rating of up to 95 HRB. This ensures minimal contact resistance and maximum thermal transfer, reducing equipment downtime on manufacturing lines.

Our operations focus on the production of strategic metallic alloys highlighted under key national industrial frameworks. We are specialists in producing specialty copper alloys including Tellurium Copper, high-conductivity Oxygen-Free Copper, Silver Copper, Dispersion Copper, and high-tensile Beryllium Copper varieties (C17200, C17500, C17510).
These products play vital roles in rapidly developing fields such as Electric Vehicle (EV) components, 5G wireless network infrastructure, high-power industrial fiber laser cutting heads, and heavy-duty battery relays. By locating our production base in Guanghan Industrial Development Zone close to major transport veins like National Highway 108, we maintain optimized transit times and logistics pipelines for both regional and international shipments.
Our goal is the alignment of green manufacturing protocols with highly reliable industrial production outputs, ensuring that heavy-duty copper products are delivered with lower footprints.
Kepai is located in the western area of the Sichuan Guanghan Industrial Development Zone, adjacent to National Highway 108. This location provides convenient transportation which forms the foundation of our logistics network.

Analyzing the specifications and supply chain expectations for modern micro-alloyed copper metals.
C17500 alloy is used to manufacture durable contact tips, electrode caps, and welding wheels that handle high thermal loads under mechanical pressure.
Used in high-voltage distribution terminals, relay contact points, and charging connection couplers demanding high conductivity and arc resistance.
C17200 Beryllium Copper provides the hardness and wear resistance required for micro-stamping lead frames and connector housings.
The manufacturing of micro-alloyed Beryllium Cobalt Copper requires precise temperature control during melting, hot extrusion, cold drawing, and aging treatment stages. Minor fluctuations in raw chemical composition can alter the precipitate distribution within the grain boundaries. Our research team focuses on refining grain sizes to reach ASTM 8 or higher, which reduces localized mechanical failure risk under cyclic load profiles.
We employ vacuum induction melting systems to minimize oxidation, producing clean alloys free of inclusions. This structural purity ensures that when parts are machined on high-speed CNC centers in Bangkok or elsewhere, the tool wear is uniform, reducing tool change cycles and micro-burring.
Additionally, we are actively researching lower-beryllium alternative alloys and optimized multi-element systems to meet evolving international ecological guidelines while preserving high mechanical strength.
Our processes are audited to international quality guidelines, ensuring consistency from batch to batch.
Each alloy batch is shipped with physical analysis certifications containing spectrographic chemical testing, electrical conductivity evaluation (IACS % values), hardness checks (HRB/HV), and dimensional variance verification. Our testing facilities feature computerized universal testers, hardness testing rigs, and chemical testing chambers to verify compliance before shipment.

Common questions regarding the selection, application, and processing of copper alloys.
C17500 Beryllium Cobalt Copper features a composition of 0.4–0.7% Beryllium and 2.4–2.7% Cobalt, offering high electrical and thermal conductivity (typically 45-60% IACS) combined with high hardness and strength. C17510 replaces Cobalt with Nickel (1.4–2.2% Nickel, 0.2–0.6% Beryllium) in specific formulations, which provides similar mechanical properties and electrical conductivity, often making it an alternative for high-performance thermal connectors and switches.
These alloys achieve their properties through precipitation hardening (aging). Solution annealing at around 900–950°C dissolves the alloying elements, followed by a water quench. The material is then aged at 450–480°C for 2 to 3 hours, causing fine beryllide phases to precipitate, which increases the material's mechanical strength and hardness while restoring electrical conductivity.
Yes, Beryllium-containing alloys in solid form are compliant with current RoHS and REACH directives. They do not contain restricted hazardous substances like lead, mercury, or cadmium above allowable limits. However, processing that generates dust or fumes, such as dry grinding or welding, requires proper local exhaust ventilation to ensure airborne particle concentrations remain below occupational exposure limits.
Due to our proximity to National Highway 108 and key rail terminals, we offer multiple shipping routes. Bulk orders are typically shipped via Chengdu-Guangdong rail links to marine terminals, followed by sea transit to the Port of Bangkok or Laem Chabang. Urgent material requirements can be dispatched via air freight from Chengdu Shuangliu International Airport. We provide export customs clearance documents, certificates of conformity, and packing lists to support fast processing.
