1mm Copper Foil Wire Braided Mesh Tube

The 1mm Copper Foil Wire Braided Mesh Tube is a high-performance shielding sleeve crafted from 99.9% pure copper foil strips woven into an expandable, continuous conductive mesh. Each flat wire strand presents a wide contact surface, achieving surface resistivity below 0.01 Ω/sq and shielding effectiveness that often surpasses 70 dB from 30 MHz to 1 GHz. Unlike traditional round-wire braids, the foil construction eliminates pinholes and gaps, providing true 360° coverage essential for sensitive automotive CAN bus lines, aerospace fly-by-wire harnesses, and medical MRI cables. The 1 mm foil thickness strikes an ideal balance between flexibility and mechanical toughness—resisting abrasion, cut-through, and vibration fatigue in engine bays and robotic joints. For projects requiring specific bundle diameters, we supply a complete size range. The 41mm Copper Foil Wire Braided Mesh Tube accommodates cable assemblies near 41 mm OD, while the 42mm Copper Foil Wire Braided Mesh Tube gives a slightly looser fit for thicker jackets. For large power distribution harnesses, the 43mm Copper Foil Wire Braided Mesh Tube and the 44mm Copper Foil Wire Braided Mesh Tube step up the inner diameter while preserving identical foil quality and electrical performance. All variants are braided on precision machines that lock a 45° braid angle, optimizing expansion and spring-back memory. The open weave promotes heat dissipation—an added benefit in high-current EV battery packs. The table below presents the core specifications shared by the entire family.

The 1mm Copper Foil Wire Braided Mesh Tube stands out for its tool-free installation. The mesh expands radially up to 150% of its nominal ID, allowing it to slide over pre-terminated connectors and then contract into a snug, conductive wrap. This eliminates the labor and risk of connector disassembly. Grounding is straightforward: the tube can be terminated with copper foil tape, crimped ring terminals, or soldered directly to chassis ground, creating a low-inductance drain path. Engineers in automotive and aerospace sectors regularly cite the following practical advantages of this copper foil tube:

• Can be cut cleanly with standard scissors or a hot knife; cut edges self-fringe slightly but do not unravel
• Memory effect keeps the braid closed after repeated expansions, preventing coverage gaps
• Lightweight profile—typical 1mm tube weighs under 95 g/m, helping meet mass reduction targets
• Resistant to common solvents, fuels, and hydraulic fluids found in engine compartments
• Optional tin-plated surface enhances solderability and withstands salt-spray corrosion (≥ 96 hours)
• Flame-retardant behavior passes UL94 V-0, an important requirement for enclosed electrical enclosures

To illustrate the performance consistency across sizes, the following table lists the most popular diameters from the 1mm Copper Foil Wire Braided Mesh Tube range. Each variant uses identical 1 mm foil and braid construction, so electrical and thermal properties remain unchanged—only the inner dimension varies to match cable bundles.

The 1mm Copper Foil Wire Braided Mesh Tube undergoes 100% inline continuity testing during braiding, ensuring every meter meets the ≤0.01 Ω/m requirement. When combined with a conductive adhesive copper foil tape at both ends, the assembly becomes a water-tight, shielded conduit suitable for marine and outdoor telecom installations. The tube also accommodates slight bends and flexing; durability tests confirm stable shielding after 50,000 flex cycles at a 90° bend radius. Custom diameters that fall outside the 41–44 mm standard window—whether smaller or larger—can be produced with the same 1mm foil specification to meet unique project demands. Its all-copper construction additionally provides a premium, industrial aesthetic for visible cable management in high-end custom builds.
