This solid tungsten cube set contains 2 pieces of 99.999% high purity tungsten metal blocks. Standard solid cube sizes include 10mm, 20mm, 25mm and 50mm. Each tungsten cube adopts independent vacuum moisture-proof sealing before combined outer packing. All blocks are produced 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 base owns natural high density and high melting point while maintaining stable chemical performance at room temperature.
This two-pack tungsten cube set is suitable for common lab and light industrial experiments such as parallel density comparison tests, vacuum evaporation PVD and CVD coating, laboratory alloy preparation, university teaching demonstrations and metal element specimen storage. Separate vacuum packaging blocks air contact to slow surface oxidation. We support FBM shipment for complete 2-piece sets to satisfy small batch procurement for researchers and material experiment enthusiasts.
