· JVASP-102688· PtW

PtW is a platinum-tungsten alloy combining the corrosion resistance and chemical inertness of platinum with the hardness and refractory properties of tungsten. This material is used in specialized high-temperature and chemically aggressive environments where platinum alone would be too soft or expensive, or where tungsten's brittleness must be mitigated—such as in electrodes, contacts, and crucibles for demanding industrial and laboratory processes.

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.
