Flexible 120C Tinned Copper Braided Mesh Tube

For demanding electrical and industrial applications that require reliable connectivity, effective grounding, and resilient electromagnetic shielding, a 120C Tinned Copper Braided Mesh Tube forms the backbone of many critical systems. Our product family delivers versatility through multiple configurations tailored to specific project needs. Where maximum conductor density and screen integrity are paramount, the High Density Tinned Copper Braided Mesh Tube provides an exceptionally fine braid angle that virtually eliminates signal leakage. In weight-conscious designs—such as harnesses for aerospace or portable equipment—the Lightweight 120C Tinned Copper Braided Mesh Tube reduces mass without compromising the 120°C thermal ceiling. When installation routing demands effortless manipulation around tight bends and irregular contours, the Soft 120C Tinned Copper Braided Mesh Tube stands out with its pliable yet durable wire construction. Each variant shares the same core attribute: a tubular braid of pure copper strands uniformly coated with tin to resist oxidation and corrosion while maintaining low electrical resistance.

The Flexible 120C Tinned Copper Braided Mesh Tube is engineered to deliver consistent performance across a wide spectrum of demanding applications, from industrial power distribution to sensitive instrumentation. Its tubular knit construction permits radial expansion and contraction, allowing the sleeve to conform tightly over irregularly shaped conductors, cable bundles, or hose assemblies. The hot-dip tinning process forms a metallurgical bond with the copper substrate, which prevents the formation of brittle intermetallic layers under thermal cycling—a common failure mode in lesser plating methods. In high-vibration environments, the braid’s inherent flexibility attenuates mechanical stress transferred to termination points, significantly extending service life. The open mesh structure also facilitates heat dissipation, promoting cooler operation during continuous high-current loads, while still achieving up to 95 dB of near-field shielding attenuation at elevated frequencies. Standard inner diameters accommodate everything from fine-gauge coaxial cables to large grounding straps, and custom tooling allows non-standard diameters to be manufactured with short lead times. Cleanroom-compatible versions are available on request, where the tube is washed and double-bagged to eliminate particulate contamination. Integrated into a comprehensive bonding and shielding strategy, this braided mesh tube serves as a durable, low-impedance path for fault currents and electromagnetic noise, helping designs comply with the emission and immunity requirements of IEC 61000-4 series standards.
