· JVASP-98313· UWC2

UWC2 is a tungsten-based heavy metal alloy, likely a uranium-tungsten composite or tungsten-heavy alloy used in specialized applications requiring high density and strength. The material belongs to a family of dense refractory metals commonly employed in aerospace, defense, and radiation-shielding applications where weight efficiency and performance under extreme conditions are critical. Engineers select UWC2 when conventional steels cannot meet density, hardness, or thermal requirements, particularly in applications where compact, high-mass components are needed in confined spaces.

Regulatory Screening

Environmental

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.
