Specially processed copper alloys matching the rigorous production requirements of Mumbai's manufacturing, electrical, and defense sectors.
Mumbai, widely known as the financial capital of India, has transitioned into a massive hub for advanced engineering, electrical equipment assembly, automotive components, and aerospace parts. The industrial zones bordering the Mumbai Metropolitan Region (MMR)—including Thane-Belapur, Taloja, Navi Mumbai, and the industrial corridors extending toward Pune—are experiencing an unprecedented technological shift. Modern engineering units are phasing out standard oxygen-free coppers for specialized free-cutting, high-conductivity copper alloys.
The local manufacturing growth is heavily backed by the Indian Government’s initiatives like "Make in India" and the domestic production of electric vehicles (EVs), renewable energy setups, and high-frequency communication infrastructure. As a result, factories in Mumbai require a dependable supply of C14700 Sulfur Copper (CuSP). This material provides the critical synergy of high electrical conductivity and excellent machinability, preventing the tooling wear and heat generation associated with machining pure copper.
Why C14700 outperforms alternative alloys in high-volume precision CNC machining environments.
| Property Parameter | C14700 Sulfur Copper (CuSP) | C14500 Tellurium Copper | C11000 ETP Copper |
|---|---|---|---|
| Chemical Composition | Cu: 99.5%, S: 0.20-0.50% | Cu: 99.5%, Te: 0.40-0.70% | Cu: 99.90% min, O: 0.04% |
| Electrical Conductivity (IACS %) | 93% - 98% | 90% - 96% | 101% |
| Machinability Rating | 85 (Free-cutting brass = 100) | 85 (Free-cutting brass = 100) | 20 (Difficult to machine) |
| Tensile Strength (MPa) | 220 - 320 (depending on temper) | 250 - 340 (depending on temper) | 220 - 380 |
| Thermal Conductivity (W/m·K) | 355 | 355 | 388 |
Sichuan Kepai New Material Co., Ltd., established in 2017, operates a modern 9,000 square meter factory coupled with a dedicated 1,000 square meter engineering office. Located strategically adjacent to National Highway 108 in Guanghan, Sichuan, our manufacturing framework is optimized around high-efficiency metallurgy. We integrate the entire raw material pipeline: from premium copper smelting and continuous casting, to high-pressure extrusion, precise drawing, straightening, and automated quality verification.
Our Factory 4.0 processing guarantees consistent material structural integrity. By deploying computerized composition monitoring and microcomputer-controlled universal testing, we ensure that every batch of sulfur copper sent to Mumbai possesses uniform grain size, exact hardness, and high conductivity. This process minimizes variances that disrupt CNC machining lines, providing a highly reliable supply chain for overseas manufacturers.
Sichuan Kepai designs specialized alloy systems to meet the unique challenges of modern technology sectors.
Our sulfur copper and high-conductivity tellurium copper rods are machined into heavy-duty contactors, electric vehicle charging socket pins, battery pack links, and relay terminals. These components manage massive electrical surges with minimal thermal accumulation.
In high-intensity industrial fabrication shops across Mumbai, plasma torch nozzles require high thermal dissipation. C14700 and C14500 alloys are chosen to resist slag accumulation, maintaining dimensional integrity under high arc temperatures.
We work directly with Indian customs agents, providing full compliance document sets including Certificate of Origin, mill test certificates (MTC), BIS certifications, and SGS test readouts. This ensures smooth clearance at the Port of Mumbai (JNPT).
With high-frequency 5G networks expanding, low attenuation is critical. Our clean, lead-free coppers allow precision micro-machining of micro-pin connectors and switches that handle high signal frequencies with zero distortion.
From smelting to high-conductivity checks, our facility manages every stage to guarantee E-E-A-T tier quality.
To serve demanding engineering hubs like Mumbai, Sichuan Kepai maintains strict quality systems. Every phase, from smelting to delivery, is fully traceable under our certified ISO quality guidelines. Our C14700 Sulfur Copper and C14500 Tellurium Copper alloys comply with RoHS and REACH regulations, ensuring safe and reliable integration into modern electronic systems.
