An important quality of our Metaza pendants is their optimal malleability rating. The diamond-tipped stylus on the Metaza engraver, through the stippling effect, must impact the metal at the proper depth to produce a vivid photo engraving image. Malleability is a physical property of metals and metal alloys, or generally of any kind of matter. A malleable metal can easily be formed, especially by hammering. Malleability shows how mobile particles involved in metallic bonding can be pushed or pulled past each other, making metals malleable and ductile. Gold is the most malleable metal, followed by aluminium.
