Application Range
Typical wire and process applications
The 111-oriented single crystal and precision-finished bore support repeatable geometry for fine and ultrafine wire. Reduction angle, bearing length and transition quality are specified with the pass schedule to protect wire roundness and surface finish across the die sequence.
Typical applications
- Fine and ultrafine copper and aluminum wire
- Fine steel, stainless steel and alloy wire
- Drawing processes where bore geometry and surface finish must remain consistent
Selection Guidance
Selecting SSCD dies for fine and ultrafine wire
Use a synthetic single crystal diamond die when repeatable fine-wire bore geometry is a priority. Confirm wire material, finished size, bearing length, casing dimensions and inspection needs when comparing SSCD with natural diamond tooling.
