This solid tungsten cube set comes with 5 pieces of 99.999% high purity tungsten metal blocks. Standard solid cube dimensions include 10mm, 20mm, 25mm and 50mm. Each tungsten cube is sealed in an independent vacuum moisture-proof pouch before being combined into one outer package as a complete set. All blocks are produced by powder metallurgy sintering and full six-side precision mirror polishing to create scratch-free smooth planes and tidy sharp edges without burrs. The low-impurity tungsten substrate owns natural high density and high melting point while maintaining stable chemical properties under room temperature.
This five-pack tungsten cube set fits daily laboratory and light industrial experimental tasks such as multi-batch parallel density comparison tests, vacuum evaporation PVD and CVD coating, laboratory alloy preparation, class group teaching demonstrations and long-term metal element specimen storage. Separate vacuum packaging isolates air contact to slow surface oxidation. We provide FBM shipment for full 5-piece sets to meet small batch procurement demands of researchers and material experiment hobbyists.
