ApplicationsTerminals for connector applications, switches, relays, IC lead frames, etc.
Copper alloy designed for connectors.
It features an improved balance of strength, springiness, and bendability over that of the NB-109.
NB-115 is a copper alloy with a superior balance of strength, springiness, and bendability.
It has excellent stress relaxation resistance.
It is well suited for downsizing, weight reduction, improving reliability, and cost reduction of electrical and electronic components.
It is registered as C19027 by the CDA (United States) and can be procured locally from Wieland in the United States.
