I know where to find the pack of bourbons!!!!!
What is the relative density of Cu?
Try this link, (below), but the density or SC is about 9

You just showing what you have forgotten or was not taught at the tech Steve
Eutectic is a term used when a substance changes its state from a solid to a liquid, with very little plastic range, (tinmans solder for example, melting point 180°c, fully liquid at 183°c) or from a solid to a gas, solid Co² changes from a solid to a gas without any liquid phase
Woods and Fields metal are metals with a very low melting point, below 100°c, and can be used in fusible links or used for the stays in sprinkler heads, instead of glass phials
Woods metal melting point 70°c
Fields metal melting point 62°c
Another interesting alloy
Rose's metal, also known as “Rose metal” and “Rose's alloy” is a fusible alloy with a low melting point. Rose's metal consists of 50% Bi (bismuth), 25–28% Pb (lead) and 22–25% Sn (tin); its melting point is 100 °C (212 °F). Rose's metal is typically used as a solder. Its special property is that it does not contract on cooling. It was used to secure cast iron railings and balusters in pockets in stone bases and steps.
Smeaton when he built the Eddystone light house, used Lead dovetails to hold the stone blocks in place on the rock after he had, had it trimmed by stone masons, to stop the seawater from getting into the dovetail cuts, when the rock was covered at high tide, he had the dovetails cut in the rock filled with tallow, which when the lead was poured melted the tallow, and because the tallow had filled the dovetails before the rising tide covered the rock and filled the dovetails with water, this stopped the lead from exploding when it was poured into the previously cut dovetails
