MWS offers High Performance Wire in Extra (XHTW) and Extreme (EHTW) tensile strength with all insulation types and as bare wire. Most alloys are available with nickel, silver, or gold plating.

MWS High Performance Wire (HPW) products are copper alloy conductors specifically designed for applications with high mechanical stress that also require high conductivity. Through improved characteristics of the wire, lifespan and reliability under dynamic load are increased.

Wire Properties

Increased Tensile Strength – Over 50% greater than ETP copper
High Conductivity – up to 89% of ETP copper
Good Solderability and Weldability – no performance loss compared to copper
Increased Bending Performance – better fatigue strength results in fewer wire breaks in cable constructions
