As the backbone of modern electrical infrastructure, Tinned Copper has emerged as the preferred material for high-performance industrial applications. In an era defined by rapid electrification, the global demand for durable, conductive, and corrosion-resistant wiring solutions is at an all-time high. Tinned copper, which consists of copper wire coated in a thin layer of tin, provides a unique synergy: the high electrical conductivity of pure copper combined with the oxidation protection of tin.
The industrial world is shifting toward environments that are increasingly harsh—high humidity, saltwater exposure, and extreme chemical conditions. From offshore wind farms in the North Sea to solar arrays in the Sahara, tinned copper is the essential component that ensures longevity. Unlike bare copper, which oxidizes and develops a high-resistance patina, tinned copper maintains its integrity, ensuring that critical systems in telecommunications, marine engineering, and power distribution remain operational for decades.
We are currently witnessing three major trends shaping the tinned copper market:
Established in 2019 and headquartered in Liushi, the renowned "Capital of Electrical Appliances" in China, Zhejiang Xingma has rapidly evolved into a leading powerhouse in the non-ferrous metal processing sector. We specialize in the mass production of automated mechanical components, including high-purity copper wires, braided tapes, and soft connection series.
Our commitment to excellence is backed by ISO9001:2015 and ISO14001:2015 certifications. As a member of the Zhejiang Cable Accessories Industry Association, we pride ourselves on being a trusted partner for global enterprises seeking reliable manufacturing strength.

Our factory floor is equipped with the latest technology to ensure every micron of tinning is perfect.
Utilizing Dingtian wire drawing machines and Fuchuan beam machines, we achieve diameter tolerances that meet strict international aerospace and medical standards.
Our lab features microscope hardness testers and air dryers to ensure that every batch of soft copper stranded wire is free from defects and hydrogen embrittlement.
With 160-ton punching machines and automated cutting lines, we provide rapid turnaround times for custom metal stamping parts and flexible busbars.
Modern procurement managers face a volatile market. The need for Stable Supply Chains, Material Traceability, and Custom Engineering is paramount. Global buyers in the US, Europe, and the Middle East are no longer looking for just a vendor; they are looking for an extension of their engineering team.
In the EV sector, tinned copper braided connectors are vital. They handle the vibration of the moving vehicle while providing a flexible bridge between battery cells. Our products are designed to withstand the thermal expansion and contraction cycles common in fast-charging environments.
For data centers and telecommunication towers, corrosion is the enemy of signal integrity. Our tinned copper braided tapes offer superior shielding (EMI) and grounding, ensuring that sensitive electronic equipment is protected from interference and surges.
Located near Shanghai and Ningbo ports, we provide seamless global export capabilities with optimized shipping costs.
Being in Liushi means we are steps away from the raw material market, allowing us to hedge copper prices and offer stable quotes.
From initial wire drawing to final spot welding and stamping, we handle the entire process in-house, ensuring total quality control.
The core of our expertise lies in the electro-tinning process. When copper is exposed to air, it reacts with oxygen to form copper oxide, which is semi-conductive. This can lead to overheating at joint connections. By applying a protective tin layer, we ensure that the conductor remains easy to solder and free from atmospheric corrosion. This is particularly vital in marine environments where salt spray would otherwise destroy a standard copper connection in weeks.
Zhejiang Xingma utilizes concentric, bunch, and rope stranding methods. Each technique serves a specific purpose:
We recognize that our global partners operate under strict regulatory frameworks. Whether it’s the NEC (National Electrical Code) in the United States or IEC standards in Europe, our products are engineered to comply with high safety and performance benchmarks. Our high-purity T1/T2 copper ensures low resistance, while our ISO-certified production lines guarantee batch-to-batch consistency.
Zhejiang Xingma Copper Co., Ltd. will work together with you to achieve win-win results! Based on the global market, we provide reliable, high-quality, and easy-to-expand product customization solutions.
