A sample of Tungsten metal in the form of thin sheet. Purity is 99.95%. A very interesting form of W metal which is usually very expensive. Pieces are randomly fractured and vary in weight from 2.5-3g. The material is difficult to cut and will shows signs of chipping and cracking around the edges as can be seen in the photos. Please check my Bonanza store for more element samples. I have almost every collectible element available. Thanks for looking.
