Probe materials
Under the current situation where precious metals are used as materials for probes used in inspecting the electric properties of semiconductor circuits, we provide probe material products that meet a variety of different needs.
TY series and Ag-Pd-Cu-based alloys
This series includes precipitation-hardened materials that excel in contact reliability and wear and corrosion resistance, exhibit excellent mechanical properties such as spring characteristics and hardness, and provide high degree of hardness by heat treatment. You can increase hardness by heat treatment after cutting and shaping. The TY series offers choices from lines of Au- and Pd-based materials.
