Short answer: Electronics metals are chosen for conductivity and springiness: copper for conductors, phosphor bronze and beryllium copper for contacts and connectors, controlled-expansion alloys for lead frames, and rare-earth magnets for actuators, each often finished with selective plating.
At a Glance
Conductivity Comes First
Copper C11000 carries most current paths because of its high IACS rating and low cost; trade-offs are in our Conductivity Guide, Copper vs Aluminium Wire and Copper Busbar Guide.
Springy and Formable Alloys
Contacts and connectors need fatigue resistance and formability, so phosphor bronze and beryllium copper dominate; see our Phosphor Bronze Guide and Beryllium Copper Supplier.
Magnets and Special Parts
Actuators and sensors use rare-earth magnets and specialty strips; our Rare-Earth Magnet Guide and Cobalt Alloy Supplier cover the materials.
Plating and Finish
Selective gold, tin or nickel plating controls contact resistance and solderability; the options are in our Electroplating Guide and Surface Treatment Guide.
Sourcing Electronic-Grade Stock
Buyers specify temper, surface and plating, then require certification; our How to Choose a Metal Supplier and Mill Test Certificate Guide frame the RFQ.
