Silver
It has the highest electrical and thermal conductivity of any metal. Combined with tungsten, it becomes a contact material that withstands arcing while conducting well.

The metal that conducts best
It carries heat away fastest. Losses are low in both heat dissipation and contacts.
It carries more current through the same cross-section.
WAg(70:30) reduces contact welding while keeping conductivity.
Key Properties
Figures are representative values. The thermal expansion coefficient is taken from published literature and needs review before release; actual delivery specifications follow the per-lot test report.
