Pins & Electrodes
Contact pins and spark plug electrodes provide reliable signal and power transmission for demanding automotive and electronic applications. Using high‑quality materials and advanced coatings that combine precious and non‑precious metals, they ensure low resistance, high efficiency, and long service life.
Contact Pins
High standards for good signal and power transmission at low resistance have to be met in electrical and mechatronic systems. Coated contact pins combine the positive properties of precious and non-precious materials, ensuring an optimal result.
About Contact Pins
Contact pins are used for signal and power transmission in assembly and joining technology, sensor technology, and medical applications. Depending on external conditions, contact pins must offer high workability and allow a high degree of flexibility in material selection.
Heraeus contact pins combine the advantages of precious and non‑precious materials. A non‑precious metal core is coated with precious metals in accordance with ASTM standards. This material combination provides precisely defined properties, ensures corrosion resistance, and supports a long service life while maintaining cost efficiency.
Contact pins are available in a wide range of materials and lengths and can be manufactured according to individual specifications. Optional stamping at defined positions on the contact pin is also available.

Electrodes for Spark Plug Applications
Spark plug electrodes are available as continuous and cut wires, rivets, balls, discs, and crosses.
About Electrodes for Spark Plugs
High‑quality precious‑metal‑based materials are increasingly used for spark plug electrodes due to their high thermal stability and long service life, achieved through excellent wear and oxidation resistance. Mechanical properties can be tailored to specific processing and workability requirements.
By enabling more efficient fuel combustion and reduced CO₂ emissions, these materials support compliance with future environmental standards. Electrode materials for center and ground electrodes are manufactured from high‑performance platinum‑group metal alloys, providing significantly longer service life than conventional spark plugs with non‑precious metal electrodes.
