Surface treatment of our wire rope isolators

The method of surface treatment of our wire rope isolators has been changed. We have replaced the so-called hexavalent chromium (Cr+6) in the plating process with E-clps 3+, which is a more environment friendly process and according to EU-regulation RoHS.

The new Cr+3 plating process results in equivalent plating rate, hardness, and current efficiency compared with Cr+6 plating, and will not effect the price. However, with the new surface treatment the wire rope isolator will have a white “natural” aluminum color instead of the previous yellow.
