Eutectic alloys for soldering, both traditional alloys composed of lead (Pb) and tin (Sn), sometimes with additional silver (Ag) or gold (Au) — especially Sn 63 Pb 37 and Sn 62 Pb 36 Ag 2 alloy formula for electronics - and newer lead-free soldering alloys, in particular ones composed of tin, silver, and copper (Cu) such as Sn 96.5 Ag 3.5.
Good general purpose alloy. Can be used in food industry. For ferrous and non-ferrous alloys. Used in electrical industry and for brazing parts of ships, lamps, piping, band instruments, etc. Yellow white color. Maximum service temperature 204 °C, intermittently 316 °C. 32: 33: 35: Ag 25 Cu 40 Zn 35: Ag–Cu–Zn 700/790 [1] – AG 205, L-Ag ...
A non-eutectic alloy used for die attachment of silicon dies. Ultrasonic assistance is needed to scrub the chip surface so a eutectic (3.1% Si) is reached at reflow. Au 96.8 Si 3.2: 370 [16] 363 [95] Yes: Yes: Au97. [77] AuSi 3.2 is a eutectic with melting point of 363 °C.
Wood's metal, also known as Lipowitz's alloy or by the commercial names Cerrobend, Bendalloy, Pewtalloy and MCP 158, is a metal alloy that is useful for soldering and making custom metal parts, but its fumes are toxic, as well as being toxic on skin exposure. The alloy is named for Barnabas Wood, who invented and patented the alloy in 1860.
Linotype or eutectic alloy is a broad name applied to five categories of lead alloys used in manufacture of type, especially for the Linotype machine, each with three to five sub-classifications. One alloy is composed of lead with 4% tin and 12% antimony.
Eutectic bonding, also referred to as eutectic soldering, describes a wafer bonding technique with an intermediate metal layer that can produce a eutectic system. Those eutectic metals are alloys that transform directly from solid to liquid state, or vice versa from liquid to solid state, at a specific composition and temperature without ...

Tin-silver-copper (Sn-Ag-Cu, also known as SAC), is a lead-free alloy commonly used for electronic solder.It is the main choice for lead-free surface-mount technology (SMT) assembly in the industry, [1] as it is near eutectic, with adequate thermal fatigue properties, strength, and wettability. [2]
