Molybdenum may not be well known in the collective mind of the public but figures prominently in the world of metallurgy as one of the ingredients that, together with iron, makes steel. "Moly steel" is a collective term used for many steel grades containing varying amounts of molybdenum all of which yield much higher strength than iron alone. In metallurgical terms strength is that property that allows the object to retain its shape under a load; ie. a steel plate not buckling when a weight has been placed on it.
Here we have about 5 grams of pure molybdenum for your collection.
