Products
- Wire-D = 0.06 - 11mm diametre
- Ribbn-W 0.4-40mm,T=0.05-2.90mm
- Strip W8-200mm,T-0.1-3.0mm.
Applications
Heating cables, Fuses, Shunts, resistors and various types of controls. They have excellent resistance to sea water corosion, low macro fouling rates and good fabricability. Used on oil sea rigs.
