Annotation

This specification covers low-melting point metal alloys and soldiers, including bismuth-tin, bismuth-lead, bismuth-tin-lead, bismuth-tin-lead-cadmium, bismuth-tin-lead-indium-cadmium, bismuth-tin-lead-indium, indium-lead, indium-lead-silver, and indium-tin joining together two or more metals at temperatures below their melting points; blocking for support and removable borders; radiation shielding; fusible plugs; fuses; tube bending; and punch setting. This specification shall include those alloys having liquidus temperature not exceeding the melting point of the tin lead eutectic, and alloys in the form of solid bars, ingots, powder and special forms, and in the form of solid ribbon and wire. The composition of the alloys shall conform to the chemical requirements for bismuth, lead, tin, cadmium, indium, silver, copper, antimony, and zinc. Alloys shall be tested and shall conform to specified values for alloy freezing point, and powder mesh size.
