Norsok M503 Earth Bonds

Norsok M503 Earth Bonds

Hybrid stainless steel / copper bonds use copper braid with stainless steel end fittings. This is an effective compromise between the strong corrosion resistance of the stainless steel and the good electrical conductivity of copper.

In the picture is a tin coated copper braid that has been silver soldered into specially made stainless steel lugs. The silver solder acts as an electrolytic protection for the copper.
