  • Patent number: 9851237
    Abstract: Proposed is a contact material constituting a slider for a fuel sender, the slider moving on a conductor in conjunction with a float moving in accordance with a liquid level, wherein the contact material includes 10 to 25 mass % of nickel and a balance of palladium. The present contact material is useful in the light of material cost in addition to corrosion resistance and durability. The fuel sender is useful for vehicles, such as FFV, using composite fuel of alcohol and the like. The present invention allows for producing a slider for a fuel sender having excellent corrosion resistance and abrasion resistance.
    Type: Grant

  • Patent number: 9375811
    Abstract: The present invention provides an active metal brazing material composed of a Ag—Cu—Ti—Sn alloy containing by weight 20 to 40% of Cu, 1.0 to 3.0% of Ti, 1.2 to 6.0% of Sn and the balance being Ag, and having a metallographic structure including a Sn—Ti or Cu—Ti intermetallic compound dispersed in a Ag—Cu alloy matrix, wherein the weight ratio Sn/Ti between Ti and Sn is 1.2 or more, and additionally the particle size of the intermetallic compound is 20 ?m or less. The foregoing active metal brazing material improves the workability of the hitherto known Ag—Cu—Ti alloy active metal brazing material and enables a critical dimension processing with a high processing rate, and can be produced by melting and casting the foregoing Ag—Cu—Ti—Sn alloy, and by subsequently plastically working the cast at a working rate of 90% or more to make finer the intermetallic compound involved.
