Copper highest melting points

Alloys of Cu-Zn-Al are readily prepared in carbon crucibles heated in an induction furnace as described by Marsdcn et al. [12]. Copper, having the highest melting point, is melted and then aluminum is added. After vigorous stirring with a carbon rod the melt is cooled to below the boiling point of zinc before zinc is... 

Several tin-based alloys, usually containing lead, antimony and copper, with a melting point of about 230 °C, are also die-cast where the very highest accuracy is required and great strength is not of importance. Their excellent corrosion-resistance to moisture makes them suitable for such components as number wheels in gas and water meters, and they have also found use in small complex components of electrical instruments. 

After their discovery, the d Elhuyar brothers wrote that no use has yet been found for the new metal but we must not conclude from this that it is entirely useless . This was an under-statement The physical properties of the metal have made it very useful in a modern society. The melting point is the highest of all elements, 3422°C. Above 1650°C it also has the highest tensile strength of all metals. Its electrical and thermal conductivity are good, 30% and 40% respectively of the values for copper. The metal can easily be melted into glass as it has the same low coefficient of thermal expansion as boron silicate glass. The metal has also a very low specific heat, which, in...
