We offer a wide range of tinsel wires, which are with highly flexible and high tensile properties, are widely used in telephone cords, speaker leads, medical electronic wires, wires and cables and other applications.

One, two or three layers of flat copper wire (foil) are spiral wound on a carrier-thread

Tinsel wire alloys

Copper

Oxygen-free high-conductivity copper (OFHC) has excellent physical, electrical conductivity and thermal resistance properties. Alloy CDA 10100 and CDA 10200 are available.

Alloy Copper content Min tensile strength Electrical conductivity IACS 20°C Features
CDA 10200 99.5% 206 100 High electrical conductivity
CDA 10100 99.99% 206 101 High electrical conductivity

Copper alloys

We have Cu-Ag alloys, Cu-Sn alloys, Cu-Mg alloys tinsel wires, by adding a small amount of silver, tin or magnesium, the properties of the copper alloys such as creep strength, fatigue life, etc. are greatly improved, but the conductivity is not declined too much.
