Super Flex RA Foils (HA & HA-V2)
A treated rolled copper foil designed with large crystal grain and uniform crystal orientation.
Outstanding flexibility minimizes cracking. Vibration resistance is greatly improved.
Features of HA & HA-V2
- HA and HA-V2 have much better bendability than regular rolled annealed copper foil.
- HA-V2 exhibits good handling behavior while maintaining high flexibility.
