Abstract
A composition for making a contact contains predetermined amounts of cobalt and sulfur and has a predetermined average particle size. The composition for making the contact includes a nickel-cobalt alloy containing 20% by weight to 55% by weight of cobalt, and 0.002 part by weight to 0.02 part by weight of sulfur with respect to 100 parts by weight of the nickel-cobalt alloy, the composition having an average particle size of 0.10 μm to 0.35 μm. The contact made with the composition may be included in a connector.
Claims7
A contact comprising:
- a retaining section fixed by an insulator;
- a contact section that makes sliding contact with a conductive member;
- and
- an elastic deformation section that connects the retaining section and the contact section to each other, and that is elastically deformable,
- at least the elastic deformation section containing a composition for making the contact, the composition including:
- a nickel-cobalt alloy containing 20% by weight to 55% by weight of cobalt;
- and
- 0.002 part by weight to 0.02 part by weight of sulfur with respect to 100 parts by weight of the nickel-cobalt alloy,
- the composition having an average particle size of 0.14 μm to 0.35 μm.
