Nickel Aluminium Bronze and Inconel

Nickel Aluminium Bronze and Inconel

(OP)
Would there be any reasons not to use nickel aluminium bronze and inconel in the same environment.

RE: Nickel Aluminium Bronze and Inconel

In what sense: electrically connected?  What environment?  Coupled in seawater, the NAB will be the anode and will suffer enhanced corrosion.  How much depends on many additional factors.

RE: Nickel Aluminium Bronze and Inconel

NAB has pretty good corrosion resistance, but a couple with 625 would drive selective dealloying.  If they are not coupled it should be fine.

(OP)
They would be coupled together to form a valve body and seal and would be in contact with seawater.

RE: Nickel Aluminium Bronze and Inconel

(OP)
We normally would be using Monel 400 but have no stock. We need to find a replacement material fast and have 625 in stock.

RE: Nickel Aluminium Bronze and Inconel

I would not suggest that 625 has good enough crevice corrosion resistance for a seawater valve seat.  Try looking for one of "C" type alloys.
