    摘要： Problems: A conventional alloy for a fusible plug contained harmful elements such as Cd and Pb, and there was a concern of pollution by these harmful elements. The present invention provides a fusible plug which does not contain the harmful elements Cd and Pb, with which the alloy is not forced out of the fusible plug even when used for long periods as a safety device for refrigeration equipment, and which has a strong mechanical strength such as creep strength.Means for Solving the Problem: A fusible plug employs an alloy for fusible plugs which comprises 5-8 mass % of Sn, 31-34 mass % of Bi, 0.2-4 mass % of Sb, and a remainder of In and which melts at approximately 66-70° C. A total of at most 2.0 mass % of at least one element selected from strengthening elements consisting of 0.1-1.0 mass % of Cu, 0.1-1.0 mass % of Ge, 0.1-0.7 mass % of Ag, 0.1-0.6 mass % of Au, 0.2-0.6 mass % of Zn, 0.02-0.1 mass % of Ni, and 0.01-0.1 mass % of a lanthanoid may be added.

    摘要： The present invention is directed to overcome such a problem associated with a sprinkler head made of In-based alloy with no use of Pb or Cd that in contradiction with the fact that a testing temperature in a strength test of a sprinkler head is proximal to a melting temperature of a solder alloy used in a heat-sensitive decomposition structure of the sprinkler head, and therefore a good creeping property over a higher temperature zone in which a sprinkler is activated is required, typically, the sprinkler head made of the In-based alloy with no use of Pb or Cd could not achieve the creeping property over the higher temperature zone in which the sprinkler is activated as favorably as any conventional sprinkler head using Pb or Cd could do, and could occasionally end in failure in a durability test.To solve the above problem, the present invention provides an alloy usable for a heat-sensitive material in a sprinkler head, which is composed of Sn in an amount of 0.1-2.0% by mass, Bi in an amount of 31-37% by mass and In for balance for a temperature range around 70-75° C. or which is composed of Zn in an amount of 0.05-0.4% by mass, Bi in an amount of 43-55% by mass and In for balance for a temperature range around 90-95° C.
