1.1 This specification covers low-melting point metal alloys and solders, including bismuthtin, bismuthlead, bismuthtinlead, bismuthtinleadcadmium, bismuthtinleadindiumcadmium, bismuthtinleadindium, indiumlead, and indiumleadsilver, and indiumtin 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.

1.1.1 This specification shall include those alloys having a liquidus temperature not exceeding 361°F (183°C), the melting point of the tin lead eutectic.

1.1.2 This specification includes low-melting point alloys in the form of solid bars, ingots, powder and special forms, and in the form of solid ribbon and wire.

1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.

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.
