alloys density - Alloys Density
alloys density - Nies and Winkelmann examined the density of metals in a solid and in a liquid state, and found that, contrary to the generally accepted views on the subject, many melted metals expand when they solidify. Tin, slowly and carefully heated to its melting-point, floated on melted tin, and rose to its surface even after it had been submerged. By attaching pieces of copper to the floating tin, it was found that the increase of density by melting over solid tin was 0.7 per cent., a difference which is almost as great as that between, tin at the freezing and the boiling points of water. Lead and cadmium did not yield as decisive a result. Zinc, however, behaved like tin, but showed only a contraction of 0'2 per cent. In the case of bismuth, the floating test is very easily carried out, as this metal shows as much as 3 per cent. Copper and iron showed a slight difference, the peculiarity in the case of iron being well known, and having been the subject of elaborate investigations by Wrightson.
The following table of the alloys, whose density is greater or less than the mean of their constituents, is given by several writers:
