The material and pin design should selected to
ensure that the strength the connection does not deteriorate substantially
over time, leading increase the contact resistance.04-0.4 thick. These materials are subject fatigue through time,
temperature and stress.5 Wire-Wrap Terminal
For the sake completeness, wire-wrap terminals will discussed briefly. Brass (copper/zinc),
bronze (copper/tin) copper beryllium are used, depending the size and
