Tungsten is a refractory transition metal prized for its extreme hardness, highest melting point of any element, and exceptional density. It is widely used in high-temperature structural applications, radiation shielding, electrical contacts, and cutting tools where thermal stability and wear resistance are critical performance drivers. Engineers select tungsten when operating conditions exceed the capabilities of steel or nickel alloys, or when density and radiation absorption are primary design constraints.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
