CADMIUM REPLACEMENT TECHNOLOGY: ZnCo for Cadmium



 

HELLO,

PLEASE CLARIFY WHETHER ZN-CO ALLOY COATINGS CAN BE USED AS AN ALTERNATIVE FOR CADMIUM COATINGS AT ELEVATED TEMPERATURE CONDITIONS OF AROUND 700 F TO 1000 F ON FASTENERS.ESPECIALLY.

IF SO PLEASE LET ME KNOW THE DETAILS OF THE TECHNOLOGY.

WITH REGARDS,

HARISH.S.N.

Just an observation but cadmium should not be used over about 500 F as it melts.

Dear Harish,

Neither should any Zinc platings serve particularly not Zinc cobalt as it will rupture. You may try Zinc Nickel to the exact temperature you will require in service instead of aiming high just for the fun of it.

all the best.
