The spring is inside a howsing, what I mean is think of a pogo test pin, the type you use for programming boards.
My instinct does indeed say type II grade D (The hardest choice). 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...
Hi TVP, I believe Beryllium copper is the best material for this application given all the parameters. 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...
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...
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...
