Abstract
The present invention relates to a fusible alloy for pressure relief devices (PRDs), and the present invention provides a fusible alloy for PRD, the alloy comprising 29.0 to 33.0% by weight of Bi, 14.0 to 21.0% by weight of Sn, 2.0 to 5.0% by weight of In, and substantially Pb for the balance. The fusible alloy for PRD of the invention has a melting point appropriate for use according to the 110° C.-grade standards, and has excellent wettability upon melting.
Claims
