Engineered for CNC high-speed machining, high conductivity, and absolute reliability.
Verona is not just an artistic jewel of Italy's Veneto region; it is a vital engine in Southern Europe's manufacturing framework. Local sectors range from specialized automotive components and HVAC solutions to high-precision valve engineering and fluid systems. Modern CNC machine shops in Verona face escalating pressures to increase raw machining speed, reduce cutting-tool wear, and eliminate hazardous substances (like lead) from their production streams to satisfy EU environmental directives.
This is where Sulfur Copper (UNS C14700 / CuSP) steps in. Adding controlled percentages of sulfur (0.2% to 0.7%) to pure copper provides a superb machinability rating of 85% relative to free-cutting brass (C36000), while preserving a high electrical conductivity rating of up to 98% IACS. It bridges the gap between the soft, gummy nature of pure copper (which causes tool entanglement) and the machinability of leaded alloys, enabling Verona's high-tech manufacturing plants to achieve superior efficiency without compromising material purity.
Decisions backed by precise engineering data. How C14700 compares to lead-brass and tellurium copper.
Many designers in Verona’s industrial zones face the choice between Tellurium Copper (C14500), Sulfur Copper (C14700), and traditional Leaded Brass (C36000). While Tellurium copper boasts similar properties, sulfur copper is increasingly favored for specific high-volume, automated processes due to its structural consistency and cost profile.
| Property / Alloy | C14700 (Sulfur Copper) | C14500 (Tellurium Copper) | C36000 (Leaded Brass) | C10200 (Oxygen-Free Copper) |
|---|---|---|---|---|
| Machinability Index | 85% | 85% | 100% | 20% |
| Electrical Conductivity | 90 - 98% IACS | 90 - 98% IACS | 26% IACS | 101% IACS |
| Thermal Conductivity | 350 W/(m·K) | 355 W/(m·K) | 115 W/(m·K) | 391 W/(m·K) |
| Environmental Aspect | RoHS / REACH Compliant | RoHS / REACH Compliant | Contains Lead (Restrictions Apply) | RoHS / REACH Compliant |
| Best Applications | Contact Pins, Welding Tips, Relays | Plasma Nozzles, Gas Cutting Tips | Fasteners, Plugs, Locks | Busbars, Vacuum Electronics |
For companies based in Northern Italy, the shift towards C14700 is driven by regulatory sustainability and processing cost optimization. As restrictions tighten on lead, Verona's automotive tier-1 suppliers rely on sulfur copper to design the next generation of high-conductivity electric vehicle connector pins.
A world-class strategic copper alloy manufacturer delivering directly to European industrial centers.
Established in 2017, Sichuan Kepai New Materials Co., Ltd. is a high-tech enterprise dedicated to the research, development, and high-precision production of advanced special copper alloys. Covering an area of approximately 9,000 square meters, featuring 1,000 square meters of specialized office space, Kepai delivers specialized solutions aligned with national and international industrial development initiatives.

How current environmental policies shape the future demand of the sulfur copper supply chain.
In the era of environmental, social, and governance (ESG) targets, Verona manufacturers face strict regulatory scrutiny. Standard leaded copper alloys are being phased out due to the EU RoHS directives. To substitute lead without losing machinability, industries must transition to alternative elements like sulfur and tellurium.
At the same time, the transition to green mobility requires immense volumes of copper components capable of handling high electrical currents. EV charging pins, battery terminal connectors, and internal relays must possess exceptional thermal dissipation properties. Sulfur copper’s 98% IACS conductivity minimizes power losses and prevents localized overheating, ensuring safe operation at high power levels.
Sichuan Kepai supports this transition by offering completely certified, RoHS-compliant C14700 sulfur copper. Our clean production lines prioritize energy efficiency, reducing the overall carbon footprint of our metals before they arrive at European ports.
