A spark erosion cutting wire electrode, comprises a consumable cladding of a high speed cutting inner layer and a thicker precision cutting zinc-based outer layer. A wire electrode, for spark erosion cutting, has a tensile load bearing electrically conductive core and a consumable cladding which comprises a high speed cutting inner layer of a homogeneous alloy composition and a precision cutting outer layer of a composition with a zinc content of greater than 80%, the outer layer being up to five times thicker than the rest of the cladding. An Independent claim is also included for production of the above wire electrode. |
