Ir4W
metal· JVASP-106797· Ir4W
Ir4W is a high-density iridium-tungsten alloy combining two of the densest refractory metals, designed for extreme-environment applications requiring exceptional hardness, thermal stability, and resistance to corrosion. This alloy is typically used in specialized aerospace, nuclear, and precision engineering sectors where conventional superalloys reach their performance limits, and is valued for applications demanding both weight efficiency and material integrity at elevated temperatures or in chemically aggressive environments.

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.
