Copper Braid Rope

We manufacture and export Copper Braid Rope. Our range of Copper Conductor/Conductors also includes Copper Braid Rope.

Round braids are used for carbon brushes, relays, gaskets, telecom, automobiles , earthing etc.
Our most economical standard Round copper braids are made from 0.20 diameter wire and are braided into a tube followed by a rolling process.

They are used as earthing straps and are also used in numerous electrical components. Highly copper flexible bare, tin & silver coated. Round braids are used for carbon brushes, relays, gaskets, telecom, automobiles, earthing etc.

Our wide range of copper braid products is available in the following copper wire finishes:

• Bare copper / Plain copper / red copper
• Electro tin plated copper
• Electro nickel plated copper
• 99.99% pure Silver electro plated copper
• Enamel coated, which insulates each wire
• And other finishes on request.

Even though many of our products are standard items, we also make special tailor made products made exactly to the requirements of our customers.

We offer a wide choice of braid types (flat, round, rope and layered), strand sizes, finishes, termination options (crimped, pressed and swaged), insulation and identification. Our highly flexible earthing connectors and earth leads are commonly used in switchgear, building services and a wide range of industries. We offer competitive pricing and ex-stock or short lead time deliveries.
These can be made from electrolytic copper Cu-ETP (grade C101) or from oxygen free copper

Copper Braid Construction
The construction of Copper braid is usually written as:
48 / 30 / 0.15, where:
48 = the number of carriers
30 =the number of wires per carrier
0.15 = the diameter of each wire in mm
The cross sectional area (CSA) of a copper braid can be calculated from this information:
(Carriers x wires per carrier x wire diameter ² x 3.142) / 4
So, for a copper braid with the specification: 48 / 30 / 0.15, this would be:
48 x 30 x 0.15² x 3.142 / 4 = 101.80
=25.45 mm²

Oxygen Free Copper
Oxygen-free high thermal conductivity (OFHC) copper is widely used in cryogenics. OFHC is produced by the direct conversion of selected refined cathodes and castings under carefully controlled conditions to prevent contamination of the pure oxygen-free metal during processing. The method of producing OFHC copper insures extra high grade of metal with a copper content of 99.99%.

With so small a content of extraneous elements, the inherent properties of elemental copper are brought forth to a high degree. Characteristics are high ductility, high electrical and thermal conductivity, high impact strength, good creep resistance, ease of welding, and low relative volatility under high vacuum. We supply a range of oxygen free copper for use in scientific, industrial and medical processes.

- Copper alloy 10100 oxygen free copper, also known in Europe as Cu-OF or CW008A to EN13601.
- Composition: Copper 99.99 %, Trillium 0.001 %
- Hardness: B30 - 40
- Conductivity: 101 %
- Tensile strength: 25 - 40 Ksi

In simple terms the thermal conductivity of pure copper is about 400 watts per meter . This means that a plate of copper with area A and thickness L whose faces are kept at a constant relative temperature difference of delta T will conduct heat at a rate of 400.
