INCREASED TENSION WIRE - ITW
General Description
ELEKTRISOLA increased tension wire (ITW) is a copper alloy specially designed for applications with high mechanical requirements. With a tensile strength increased by 20 - 25% compared to copper, this wire can be used in applications with higher requirements for bending proof performance and reliability.
Increased tension magnet wire is available with all insulation and self-bonding enamel types.
Features
- High tensile strength
- Good bending proof performance
- Very high conductivity
- Complies with RoHS and WEEE
Applications
- Voice coils (e.g. in micro speakers, ...)
- Others
