<p>[QUOTE="Lehigh96, post: 2106786, member: 15309"]All of the metals used in making coinage are very malleable. The pressure from the dies is not enough to liquify the surface metal of the planchet. Though I would love to hear your explanation of malleability of the elements, coins are typically made from alloys which can drastically change the physical properties from those of the elements used in the alloy. For example, both strontium and aluminum are very soft metals, but when combined in an alloy, aluminum-strontium becomes very hard and brittle depending upon the concentration of strontium added. The industrial application of aluminum-strontium is for aluminum alloy car wheels.[/QUOTE]</p><p><br /></p>
