Home Products Clad Metals Electrical Connector Materials iON Connector Materials for Harsh Environments HIGH PERFORMANCE ION CONNECTOR MATERIALS FOR HARSH ENVIRONMENTS Alloying is what makes most metals functional – the aluminum in airplanes, steel for bridges and gold jewelry all rely on alloying to provide their properties. Electrical contact surfaces are no different, and smart metallurgy enables high performance terminal materials that stand up to the world’s extreme environments – or maybe just to reduce your costs. WHAT ARE ION CONNECTOR MATERIALS? iON connector materials are engineered alternatives to electroplated contact surfaces with contacts that are metallurgically clad into the connector. Using alloys specifically designed for the task, ion clad connectors improve temperature, wear and corrosion performance while reducing exposure to expensive precious metals. The alloy systems used in ion connectors were developed with harsh conditions in mind; whether the objective is gold replacement, high wear performance, high temperature connectors, or corrosion resistant contacts, these materials outshine electroplated systems when performance matters. Custom solutions are also available, depending on your challenge. ION VS. GOLD AND PALLADIUM ELECTROPLATING The improved performance properties are derived from the alloyed microstructure of iON materials. Manufactured as an inlay clad stripes in copper spring alloys, ion connectors have fully dense structures giving high temperature and corrosion resistant contacts. With overall contact layer thicknesses down to 0.5 µm, iON materials can be drop-in replacements to electroplated gold and palladium systems. Each iON material is specifically formulated for its application. iON Connectors Data Sheet CONTACT FINISH DESCRIPTION APPLICATIONS iON – GR A composite alloy system of silver and palladium with a noble gold enriched contact surface. A common low cost replacement for hard gold electroplated connectors, with additional benefits of improved high temperature and high vibration stability. iON – HW An ultra-hard wrought nickel-palladium base layer with a gold enriched surface. For maximum wear performance in applications with high vibration, sliding or make-break contacts. iON – HT A stable alloy system of silver-palladium-gold providing high hardness, nobility and supreme temperature stability. For ultra-high temperature connector applications with exposures to temperatures up to 350°C.
