· JVASP-127635· CrW3

CrW3 is a chromium-tungsten intermetallic compound belonging to the refractory metal alloy family, characterized by very high density and potential for extreme-temperature applications. This material is primarily of research and developmental interest for specialized high-temperature structural applications where conventional superalloys reach their thermal limits, such as aerospace propulsion systems and ultra-high-temperature tooling. Engineers consider CrW3 for environments demanding excellent thermal stability and resistance to degradation above 1000°C, though commercial availability and property optimization remain limited compared to mature alternatives like nickel-based superalloys or molybdenum-rhenium systems.

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.
