Zinc alloy want to buy Tunisia

I am writing to you relative to Tin Zinc alloy for copper coating. Currently, we are using tin to coat wires, depending on the application. I am conducting research to figure out if it could be possible to alloy tin with elements like zinc to reduce its price but by keeping the same features as well as tin.

I would like to kindly ask you if it is already used in automotive wires (copper, wire diameter down to 0.100 mm) and its behavior.
