Claims
- 1. A make-and-break contact material comprising an Ag—Ni-based alloy comprising3.1 to 20.0 wt % of Ni, Li2CO3 in an amount corresponding to 0.01 to 0.50 wt % of Li metal, and a balance of Ag.
- 2. A relay comprising the make-and-break contact material of claim 1.
- 3. A switching part comprising the make-and-break contact material of claim 1, wherein said switching part performs electrical switching through a mechanical switching operation.
- 4. A make-and-break contact material according to claim 1, wherein said contact material comprises 8.0-15.0 wt % of Ni.
- 5. A make-and-break contact material according to claim 1, wherein said contact material comprises Li2CO3 in an amount corresponding to 0.05 to 0.2 wt % of Li metal.
- 6. A make-and-break contact material according to claim 1, wherein said Ni powder is uniformly dispersed in said Ag-Ni-based alloy.
- 7. A make-and-break contact material according to claim 1, wherein said Ag powder is present in an amount that constitutes the balance of said alloy.
