I am working on product where we need pogo pins, as copper is better conductor of electricity I was searching for the copper pogo pins. After about a month of searching, it is come to my notice that most of the manufacturers are dealing with pogo pins not of copper but of brass.
Even when I inquired about the pogo pin that suited voltage specification of 250V 15A. The manufacturers insisted on using Brass than copper.
Apart from this I also seen many smart watches which were using pogo pins were using Brass instead of copper?
Is there any basic issue with using copper? What are the scenarios when we should chose Brass over the copper while building electrical connectors?
