摘要:
The present invention is an electrode material constituting a movable electrode of a thermal fuse, having a five-layer clad structure including a core material layer, an intermediate layer formed on the both sides of the core material layer, and a surface layer formed on the intermediate layer, wherein the core material layer includes Cu, the intermediate layer includes an Ag-Cu-based alloy, the surface layer includes an Ag-CuO-based oxide-dispersed strengthened alloy, and the ratio of the thickness of the intermediate layer to the thickness of the surface layer (intermediate layer/surface layer) is 0.2 or more and 1.0 or less. This electrode material can be manufactured by partially internally oxidizing a three-layer clad material in which plate materials made of an Ag-Cu-based alloy are clad-jointed to both sides of the plate material made of Cu.

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.

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 µm 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.
