بيت /gold antimony eutectic alloy
The determination of the eutectic temperatures, namely those of the eutectic A1Bi, of the pseudobinary system AISbBi, and of the ternary eutectic, was carried out by means of a differential thermocouple, similar to that described by Desch (6, p. 95). The reference body was pure bismuth, of the same weight as the alloy.

commercial purity alloys. 1. Introduction The eutectic reaction dominates the solidification transformation of most AlSi foundry alloys because more than 50 vol% of the alloy is eutectic Al and Si. With its highly ordered diamond cubic crystal structure, silicon is a faceted phase, with strongly anisotropic growth.

Eutectic Gold Tin (AuSn) with a composition of 80Au20Sn is a unique material. This particular alloy of gold tin (AuSn) is considered a solder because it has a melting temperature of 280ºC, which is lower than the 350ºC transition temperature into braze materials. Still, there are some similarities between this solder alloy and braze alloys.
