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.
