WIPO Patent Application WO/2014/021465

Kind Code:

A1

Abstract:

Provided are an alloy material having excellent electrical conductivity and high hardness and excellent workability for use in a contact probe, a contact probe consisting of this alloy material, and a connection terminal. In a compositional range of a ternary alloy of silver (Ag), palladium (Pd) and copper (Cu), Ag accounts for 17-25 at%, Pd accounts for 30-45 at% and Cu accounts for 30-53 at%, at least one of manganese (Mn), tin (Sn), silicon (Si), antimony (Sb), titanium (Ti) and magnesium (Mg) is added at a quantity of 4.5 at% or lower relative to this basic composition, and further, 0.5-3.5 at% of Mn, 1-2 at% of Sn, 0.5-2 at% of Si, 0.5-3 at% of Sb, 0.5-2 at% of Ti and 0.5-3.5 at% of Mg are added relative to this basic composition.
