China Soft 120C Tinned Copper Braided Mesh Tube Manufacturer, Supplier, Factory
Engineered for superior conductivity and mechanical resilience, the Soft 120C Tinned Copper Braided Mesh Tube delivers exceptional performance in grounding, shielding, and flexible electrical connections. This high-quality braiding combines a 120°C temperature rating with tin-plated copper wire to resist oxidation and corrosion in demanding industrial environments. For projects requiring enhanced durability, the High Density Tinned Copper Braided Mesh Tube variant offers increased strand count for lower resistance and higher current capacity. When installation demands flexibility without sacrificing conductivity, the Flexible 120C Tinned Copper Braided Mesh Tube adapts seamlessly to tight routing paths and dynamic motion. Our standard 120C Tinned Copper Braided Mesh Tube strikes an ideal balance between performance and economy, while the Lightweight 120C Tinned Copper Braided Mesh Tube reduces mass in weight-sensitive applications such as aerospace harnesses or portable equipment. Each variant is manufactured under strict process controls to maintain consistent cross-section, uniform plating thickness, and reliable electrical characteristics across production batches.
The Soft 120C Tinned Copper Braided Mesh Tube is constructed from electrolytic grade copper strands individually tinned with a uniform lead-free coating, ensuring long-term solderability and electrical stability. Its soft annealed temper allows simple forming, flaring, or compression without cracking, which significantly reduces installation effort. The open-braided tubular design provides effective heat dissipation and permits airflow, making it suitable for heat-generating busbar joints and vibration-prone connections. Because the mesh structure maintains a consistent contact area under dynamic loading, it is widely specified in transformer terminals, switchgear grounding, EMI shielding sleeves, and battery interconnects where both flexibility and conductivity are non-negotiable.

Tinned Copper Wire Braid
Tinned copper wire braid is a conductive material woven from tinned copper wires. It has good conductivity, excellent flexibility, strong corrosion resistance, and certain shielding performance. The common diameter of tinned copper wire is between 0.05mm-2.0mm, such as 0.12mm, 0.15mm, etc., which can be selected according to different current carrying requirements and application scenarios. Braiding density: There are low, medium and high densities. The higher the density, the tighter the structure, the better the strength and conductivity, but the flexibility may be slightly worse. It is generally determined according to specific usage requirements. Quande Electronics Manufacturer selects high-quality raw material oxygen-free copper wire and weaves it with a high-speed braiding machine. The product surface is not cut or burred.
Square Copper Braided Wire
The traditional square copper braided wire is braided into a copper braided belt through single or multiple strands, and then extruded into a square braided belt through the outlet of the braiding machine. It is easy to cause damage during the extrusion process. Therefore, when weaving, you must wear gloves to carefully protect the wiring. The density should not be too dense, otherwise the machine will not be able to weave and it is easy to cut the copper wire.
2.0MM Solder Wick Braid Wire
The 2.0MM Solder Wick Braid Wire is a tool used to remove excess solder from electronic components such as circuit boards. The tin-absorbing copper braid is mainly woven from copper wire. The pure copper tin-absorbing copper braid has good electrical and thermal conductivity, and can quickly transfer heat to melt and absorb the solder.
