Technical Specifications
Advanced Fin Forming Technology
The integral finning process requires a tool that can withstand extreme radial and axial forces while maintaining sharp cutting edges. Nexmek blades are profile-ground to ensure that every fin is formed with the correct root radius and tip thickness, maximizing the heat transfer surface area of the final product.
- Single-pass integral fin formation
- Reduced material stress during rolling
- Optimized for oxygen-free and phosphorus-deoxidized copper (C12200, C70600 Cu-Ni)
Technical Compatibility & Standards
Our rolling blades are available in various profiles to suit specific tube diameters and fin densities.
