what we offer

Electrical Contacts in High-Load Environments

Electrical contacts in heavy duty and mining systems must maintain performance under high current, mechanical shock, vibration, and environmental contamination. Material selection, contact geometry, and joining methods are critical to ensuring long service life and consistent electrical performance.

Contact Materials for High-Current Switching - Silver alloys and refractory materials engineered for wear resistance, arc management, and thermal stability.
Refractory Contact Systems - AgW, AgWC, CuW, and related materials designed for high-load interruption and arc erosion resistance.
Discrete Contact Components - Precision-formed tips, rivets, and contact elements for consistent switching performance.
Integrated Contact Assemblies - Contacts joined to copper and alloy substrates, including brazed and welded subassemblies.
Bus Bar and Power Subassemblies - Copper and aluminum conductors integrated with electrical contacts for high-current power distribution.
