High tension wire is special alloy wire designed for applications need the wire has higher tensile strength and anti-bending performance and designated as, DHT, SDHT, UDHT as described below. The wire has tensile strength 25% higher than pure copper wire, more durable, higher conductivity and with better anti-bending performance. Because HTW mostly used in electro-acoustic area, the wire usually is self-bonding wire.
The wire is widely used in high class voice coil(micro speaker), receiver, magnetic head coil, mobile phone coil, moving coil.
Application:
Item | Cu | DHT | SDHT | UDHT |
Tensile strength(MPa) | 240-270 | 290-340 | 350-390 | 400-450 |
Yield strength(MPa) | 120-160 | 170-230 | 250-290 | 300-350 |
Bending proof performance(%) | 100 | 125 | 560 | 910 |
Conductivity(%) | 100 | 95 | 88 | 77 |
Features:
● The tensile strength is 20%-90% higher than copper wire (suitable for high winding process, prevent breakage of wire at pin connection). | ||||||||||
● Conductivity >77% | ||||||||||
● The properties of insulation and self–bonding layer is the same as enameled copper wire. | ||||||||||
● Good solderability, the same as enameled copper wire. |
