Low-melting alloys

Low-melting alloys

Rose's alloy, composed of bismuth, tin and lead, melts at 94 °C. Pure bismuth has few technical applications (in instruments for magnetic measurements), but is widely used both in the form of salts (pharmaceuticals, cosmetics, enamels) and in metallurgy together with other metals. With lead, tin, cadmium, antimony, bismuth forms alloys whose melting point is generally below 100 °C: they are alloys with high specific weight, very fluid. They undergo virtually no solidification contractions and have a low coefficient of expansion. They are used in welding, for the preparation of moulds, for making impressions, for fixing punches and dies, for the construction of safety valves, for the production of printing characters, and as a hardening bath. In addition to the Rose alloy mentioned above, the following should also be mentioned: Newton's alloy (bismuth, lead, tin), melting point 94.5 °C; Wood's alloy (bismuth, lead, tin, cadmium), melting point 65.5 °C; Lipowitz's alloy (like the previous one, but with different percentages), melting point 60 °C. The alloy composed of bismuth (50%), lead (27%), tin (13%), calcium (10%) is used for the manufacture of dies and punches for cutting and stamping metal sheets.
