PW
metal· PW
PW is a tungsten-based metal or tungsten alloy, likely a powder metallurgy or composite formulation given the designation. Tungsten and its alloys are valued for extremely high melting points, exceptional density, and superior hardness, making them essential in high-temperature and radiation-shielding applications where few alternatives perform adequately. Engineers select tungsten-based materials when operating conditions demand materials that maintain strength at extreme temperatures or when maximum density is required in compact designs, such as in aerospace, nuclear, and precision machining applications.

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.
