Contact Bonding: Electrical

Graphite and carbon components are used for their high electrical and thermal conductivity, and low friction properties. They find application in electrical sensors, power leads, feed throughs and motor brushes.

When attaching metal conductor leads, S-bond chemically binds the solder to the carbon surfaces and creates a joint that is many times more conductive than any mechanical attachment such as staking or epoxy. S-Bond joining (graphite-metal bonding) creates metallurgically bonded solder connections and enables lower profile electrical connections, especially useful for small sensors and brushes. S-Bond joining is also finding application in much larger electrical connections between carbon brushes for use on electrical trains.

Power electrical contact bonding involves the joining of many dissimilar materials. The excellent electrical conductivity of S-Bond alloys make them suitable candidates for copper-aluminum bonding of conductor busses to many silver and/or copper filled composite materials that use hardened phases such as tungsten carbide (WC) to provide resistance to hard switching contacts.
