Tungsten is a chemical element with symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively combined with other elements in chemical compounds rather than alone. In its raw form, tungsten is a hard steel-grey metal that is often brittle and hard to work. If made very pure, tungsten retains its hardness (which exceeds that of many steels), and becomes malleable enough that it can be worked easily. -Wikipedia Half Dollar and Quarter not included ProductSiteLaunchDate : 2020-07-12T00:07:50.732Z SupplierDeclaredDgHzRegulation : not_applicable UnspscCode : 31191600
