Nad I am also leaning towards class 0 based on the IEEE paper. However as you can see I feel a little over my head...

Regarding the environment, this part is for outdoor use, temp -50 to +75°C, and humidity will be of concern, howeever the housing will keedp the part safe from particles. My orriginal guess was...

    Gold Plating on Spring

    The reason for the gold plating on the spring is to prevent the galvanic corrosion. Our electrical engineer specs the maximum resistance allowable by the spring. I evaluated the material choices, I.E. Music wire, SS, Phosphorus bronze, and beryllium copper. Both the beryllium copper and...

    Gold Plating on Spring

    I need to spec an appropriate MIL-SPEC-45204C gold plating to go over a Beryllium copper spring C172. The spring is going against a housing that is also gold plated so we are worried about galvanic compatibility. What would be the correct type, grade and class? How do you usualy come up with...
