This solid tungsten metal cube features 99.999% high purity tungsten raw material and comes in single 1 piece vacuum sealed package. Standard solid cube dimensions include 10mm, 20mm, 25mm and 50mm. Every tungsten block is manufactured via powder metallurgy sintering process with full six-side precision mirror polishing treatment, creating smooth scratch-free flat surfaces and tidy sharp edges without burrs. The ultra-low impurity tungsten base carries natural high density and high melting point while keeping steady chemical features under room temperature.
This tungsten cube fits regular laboratory and light industrial experimental applications such as material density comparison testing, vacuum evaporation PVD and CVD coating, lab alloy formulation, university teaching demonstrations and metal element specimen collection. Independent moisture-proof vacuum packaging avoids direct air contact to slow oxidation. We offer single unit FBM shipment to meet small batch procurement demands for researchers and material experiment hobbyists.
