Thank you for the answer. The reason I asked for this is that I am currently in contact with some Chinese OEMs to make some customs very high current beryllium copper springs, or phosphor bronze springs.
Also, I had completely forgotten about led4power’s springs. But they can “only” handle 6-7A. So, I decided to take it into my ones hands so we can get the best springs available in the same size category.
I have asked them quotes for 200pcs to 1000pcs depending on the seller for these materials:
C54400 Phosphor Bronze B2 with 19% IACS
C17530 Beryllium Copper at 38% IACS
C17500 Beryllium Copper with 45% IACS
From what I have asked from a materials engineer friend(I am so lucky to be friends with him), it would be best to take 38% C17530 Beryllium Copper as it is much easier to machine and less susceptible to compression compared to C17500 45% IACS. What do you think?
