This solid tungsten cube set contains 3 pieces of 99.999% high purity tungsten metal blocks. Standard solid cube dimensions cover 10mm, 20mm, 25mm and 50mm. Each tungsten cube is sealed in an independent vacuum moisture-proof bag before being packed into one outer pouch as a complete set. All blocks are made by powder metallurgy sintering and full six-side precision mirror polishing to form scratch-free smooth planes and tidy sharp edges without burrs. The low-impurity tungsten substrate carries natural high density and high melting point while keeping stable chemical properties at room temperature.
This three-pack tungsten cube set works well for regular lab and light industrial experiments including multi-group parallel density comparison tests, vacuum evaporation PVD and CVD coating, laboratory alloy preparation, group teaching demonstrations and metal element specimen collection. Separate vacuum packaging isolates air contact to slow surface oxidation. We offer FBM shipment for full 3-piece sets to fulfill small batch procurement needs of researchers and material experiment hobbyists.
