metal

· JVASP-8361· WF5

WF5 is a tungsten-based metal or alloy, likely containing tungsten as the primary constituent with unspecified alloying elements. The material belongs to the family of high-density, refractory metals valued for applications requiring exceptional hardness, thermal stability, and resistance to extreme conditions. WF5 is used in applications where density, wear resistance, and high-temperature performance are critical, including aerospace components, armor systems, and industrial tooling; its tungsten base makes it a notable choice where weight-to-strength ratios or neutron shielding properties are relevant compared to steel or aluminum alternatives.

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.
