Stock sale of domestically produced pure tungsten cap screw bolts.
We sell pure tungsten, which is a difficult material to work with, starting from one cap screw bolt. Characteristics of tungsten: - High melting point (the highest among metals at 3622°C) - High density (19.3g/cm³, almost equivalent to gold) - Low thermal expansion rate (4.5μm/m·K) - X-ray shielding properties Sizes range from M3 to M8, lengths from 6 to 35mm (size chart available in the catalog). Other sizes can also be accommodated. We can also handle molybdenum, niobium, tantalum, and other materials.
