Lightweight 120C Tinned Copper Braided Mesh Tube
Engineered for reliable electrical bonding and electromagnetic shielding, our tinned copper braided mesh tubing series delivers exceptional performance across diverse industrial environments. The range features multiple configurations to match precise project demands, including a High Density Tinned Copper Braided Mesh Tube that maximizes current-carrying capacity through a tightly woven structure, a Flexible 120C Tinned Copper Braided Mesh Tube suited for routing around tight corners without compromising connection integrity, a robust 120C Tinned Copper Braided Mesh Tube that balances tensile strength with reliable service at elevated temperatures, and a Soft 120C Tinned Copper Braided Mesh Tube prized for its conformability in wrapping irregular bus bars and cable assemblies. Each variant is produced from high-purity copper strands electroplated with a uniform tin coating, ensuring optimal corrosion resistance and low contact resistance even in humid or mildly corrosive atmospheres. Consistent braid angles and controlled strand tension guarantee repeatable mechanical and electrical characteristics, helping engineers streamline grounding, bonding, and EMI/RFI mitigation tasks across power generation, telecommunications, transportation, and marine sectors.
The Lightweight 120C Tinned Copper Braided Mesh Tube addresses applications where reducing system mass is critical without sacrificing the conductive and shielding properties of full-weight copper braids. Constructed from fine-gauge tinned copper wires woven into an open tubular braid, this variant achieves significant weight savings while maintaining a continuous 120°C thermal rating. The mesh geometry provides inherent flexibility, enabling easy manipulation around cable harnesses, hydraulic lines, and structural members. Its lightweight nature simplifies handling during installation and lessens the mechanical load on supported components, making it particularly suitable for aerospace, defense, and portable equipment designs where every gram counts. Despite the reduced material content, the tinned copper construction ensures durable protection against oxidation and galvanic corrosion, preserving long-term electrical stability. This tubing can be expanded diametrically to slip over connectors and then relaxed for a snug fit, or it can be compressed for a streamlined profile inside narrow enclosures.

Cable Cord Copper Stranded Wire
The Cable Cord Copper Stranded Wire produced and sold by Quande Electronics is a conductor made of multiple copper wires twisted together, used to transmit current in cables. It has good conductivity, flexibility and mechanical strength, and is often used in power transmission, electrical equipment connection and other fields. Different twisting methods, copper wire diameters and strand numbers can be selected according to needs to meet specific requirements.
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. Quande Electronics keeps up with the latest development trends and cutting-edge technologies in the field of copper braiding, constantly updating knowledge and skills to maintain a leading position.
Copper Flexible Connecting Wire
Copper Flexible Connecting Wire is a high current conductor used to achieve flexible conductive connection between electrical equipment. It has many advantages and is widely used. Copper braided wire flexible connector: It is braided from multiple strands of copper wire, has good flexibility, and can be made into different shapes and sizes as needed.
Flat Braided Copper Wire
Flat Braided Copper Wire is a wire woven with copper wire. Usually high-quality copper wire, such as tinned copper wire, is used, which has good conductivity and corrosion resistance. There are many weaving processes, the common ones are plain weave, twill weave, etc. Different weaving methods will affect the performance and appearance of the network tube. For example, the twill weave network tube is relatively softer and has better elasticity. Quande Electronics is extremely strict in selecting raw materials, and only uses the best and most reliable materials, ensuring the high quality of the products from the source.
