- If you have a total of less than 110 springs, it is cheaper to ship small and big springs together.
- If you have a total of more than 110 springs, it is more expensive to ship big and small springs together. Therefore, I will ship the big springs separately for these guys:
Ok, one last thing before the springs are being made, as the BeCu 1mm wire has been ordered and shipped.
We initially, or rather I initially, chose zinc as plating as that would be the best compromise between cost, mechanical properties, and electrical conductivity.
However, I have thought about using nickel tin for plating instead. Because tin has a lower melting point, it would be easier to solder a bypass to than zinc, if you actually need to haha, and since it is a bit softer than zinc, it would provide about better contact area with the battery, and provide about the same electrical conductivity. And nickel substrate below the tin.
