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 и 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 и Beryllium Copper Supplier.
Magnets and Special Parts
Actuators and sensors use rare-earth magnets and specialty strips; our Rare-Earth Magnet Guide и 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 и Surface Treatment Guide.
Sourcing Electronic-Grade Stock
Buyers specify temper, surface and plating, then require certification; our How to Choose a Metal Supplier и Mill Test Certificate Guide frame the RFQ.
