Tinned Copper Flat Braid- QQ-W-343E

Tinned copper flat braid is commonly used for grounding, bonding, shielding, flexible jumpers, bus connections, equipment connections, and electrical continuity between moving or vibrating components.

Flat braid offers a broad, flexible conductor shape that can be useful in tight spaces, bonding straps, grounding paths, and applications where movement or vibration may make a rigid conductor less practical.

QQ-W-343E is a federal specification associated with copper wire and braid construction. When a project calls for tinned copper flat braid under this specification, buyers should confirm the exact braid size, construction, material, and compliance requirements.

Tinned copper has a protective tin coating over the copper strands. This helps reduce oxidation and supports better performance in applications where the braid may be exposed to moisture, air, or more demanding operating conditions.

Before ordering, confirm the required braid width, thickness, circular mil area or ampacity needs, strand construction, tin coating requirements, flexibility, termination style, and whether the braid will be used for grounding, bonding, shielding, or current transfer.
