Materion’s high-performance iON connector materials offer engineered alternatives to electroplated contact surfaces in safety-critical applications, including underhood automotive and future soldier systems. Developed for use in harsh-environment applications, iON connector materials employ standard or custom composite alloys designed to deliver specific performance properties — including enhanced resistance to extreme temperatures, vibration, and corrosion — and metallurgically clad the contacts directly into the connector material to reduce both the required amount and incurred cost of precious metal contact materials. Manufactured as inlay-clad stripes in copper spring alloys, iON connectors have fully dense structures with limited porosity, which achieves improved wear performance and contact integrity compared to electroplated contact surfaces and supports high-reliability performance in extreme environments. They also offer overall contact layer thicknesses down to 0.5µm, which allows them to function as drop-in replacements for electroplated gold and palladium contacts, and are available in three standard contact finishes. The first, iON – GR, is a composite alloy of silver and palladium with a noble-gold-enriched contact surface that offers low-cost replacements for connectors electroplated with hard gold, as well as improved stability in high-temperature and high-vibration applications. The second, iON – HW, has an ultra-hard wrought nickel/palladium base layer with a gold-enriched surface and offers maximum wear performance in high-vibration applications with sliding or make/break contacts. The third, iON – HT, is a stable silver/palladium/gold alloy that provides high hardness, nobility, and supreme temperature stability ideal for use in applications with operating temperatures as high as 350°C. Custom solutions are also available.
