1. Hmm I have not thought about a copy of the Fasttech Carobronze spring, but with BeCu 38% IACS.
2. The elasticity of 38% IACS Beryllium Copper is better than 45% IACS as it is less rigid, and has a lower chance of deflection and collapsing.
You are welcome
Also, guys, I do not know if I understood it well from one of my suppliers or not.
But APPARENTLY, I hope I am not wrong, but holy crap, I hope I understand it well, the supplier said that 2000 big springs of Beryllium Copper 38% IACS would cost, with DHL shipping:
350$US. 350 AMERICAN DOLLARS. NOT CANADIAN DOLLARYDOOS.
350$US. The cost price per spring sold, with shipping, could probably be lower than 0,30$US!
The price IS NOT FINAL
I will check with my supplier if the price is correct or not. If it is, then hallelujah!
Also, BTW, they have accepted to send 10pcs sample for 100$ US. So as expected.
I will test the samples when they get there, and see what kind of resistance they have, and comparing them to djozz’s springs testing.
Edit: The sample will add to the final price:
350$US+100$US = 450$US
Still, that is a crazy good price.
