This solid tungsten cube set includes 4 pieces of 99.999% high purity tungsten metal blocks. Standard solid cube sizes cover 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 full set. All blocks are manufactured via powder metallurgy sintering and full six-side precision mirror polishing, delivering scratch-free smooth planes and tidy sharp edges without burrs. The low impurity tungsten substrate features natural high density and high melting point while maintaining stable chemical performance at room temperature.
This four-pack tungsten cube set fits daily lab and light industrial experimental work such as multi-group 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 blocks air contact to slow surface oxidation. We support FBM shipment for full 4-piece sets to satisfy small batch procurement for researchers and material experiment enthusiasts.
