Технические характеристики
Managing Super Alloy Work-Hardening
High-nickel alloys exhibit rapid work-hardening during cold-forming. Nexmek's super-alloy blades feature a specialized 'Progressive Penetration' geometry that distributes the deformation load over a larger area, preventing the brittle fracture of fins and minimizing the radial stress on the machine spindle.
- Proprietary multi-angle flank design to reduce friction
- Engineered for materials with high nickel (30-70%) content
- Maintains ±0.015mm tolerance on fin height in hard alloys
Super Alloy Performance Matrix
Our tooling is benchmarked against the most difficult-to-form alloys in the industrial sector.
