Higher melting point gold or indium
WebGold-tin solder paste is used in a variety of applications that require a high-melting temperature (over 150°C), good thermal fatigue properties, and high-temperature … WebThe low melting point of indium solders is caused by the low melting point of indium itself, which is 157°C (315°F). It is interesting to note that the cited melting point of indium has in-creased by nearly 5°C (9°F) over the last 40 years with the development of improved refining methods, as the melting point is very sensitive to low

WebIndium is a silvery-white metal with a low melting point of 156,5985 ° C. Among the metals, only mercury, gallium and most alkali metals have a lower melting point. The metal is liquid over a very large range of almost 2000 K. Liquid indium permanently leaves a thin film on glass (wetting). The similar gallium has the same property.
Web48% tin solder has greater tensile and shear strength than 100% indium solder, but lower thermal and electrical conductivity. High-Density Low-Melting-Point Lead-Free Solder This bismuth-tin solder has similar performance properties to lead solder, but is also safe for use in food-processing equipment and copper water pipes. 1 字符串拆分成数组WebSince our founding in 1934, Indium Corporation has been the world’s leader in specialty solders and alloy development.
