Monel Rivets

Monel Rivets have been used to fix galvanised steel flashings for many years. In theory, corrosion of the galvanised steel could be expected, because zinc and monel are far apart on the galvanic scale. This does not often happen in reality because of the natural passivation of monel in normal environments, and because the area of the rivet (the cathode) is small compared to the sheeting (the anode).

The copper content of monel is low, and being alloyed with nickel, it gives good performance in most environments. In an aggressive marine or industrial environment, a barrier coating is needed to avoid any likelihood of corrosion.

N.B. Using monel rivets with Zinc/Aluminium coating may compromise the manufacturer's warranty.
