Especificações Técnicas
Engineering for High-Toughness Alloys
Rolling Copper-Nickel alloys generates significantly more heat and friction than pure copper. Nexmek blades are engineered with a specialized edge-angle that reduces the radial load while ensuring deep, clean penetration into the harder material matrix.
- Enhanced thermal stability for high-speed marine finning
- Proprietary vacuum heat treatment for a 62+ HRC core
- Micro-ground profiles to minimize material stress
Tooling Performance by Material Grade
Our Cu-Ni series blades are tested against the industry's most demanding alloy specifications to ensure longevity.
| Material Grade | Hardness (Base) | Rolling Difficulty | Tool Life Expectancy |
|---|---|---|---|
| C12200 (Pure Cu) | Soft | Low | Excellent |
| C70600 (90/10 Cu-Ni) | Medium | Moderate | High Performance |
| C71500 (70/30 Cu-Ni) | Hard | High | Heavy-Duty Rated |
Marine & Offshore Excellence
Cu-Ni finned tubes are the industry standard for seawater-cooled systems. Nexmek provides the precision tooling necessary to manufacture high-reliability components for desalination plants, naval condensers, and offshore platform heat exchangers, where failure is not an option.
