· YWN3

YWN3 is a metal alloy belonging to the tungsten-nickel-based family, designed for applications requiring high stiffness and density in a compact form factor. This material is used in precision engineering applications such as counterweights, radiation shielding, and high-density structural components where gravitational or inertial performance is critical. Engineers select YWN3 when space constraints demand superior density-to-volume ratios compared to conventional steels, or when radiation attenuation without excessive bulk is essential.

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.
