metal· JVASP-36137· HW
HW is a dense metallic material, likely a tungsten-based alloy or heavy metal composite given its very high density. Without specified composition details, it probable belongs to the family of dense refractory metals or tungsten heavy alloys commonly used where weight and density are critical design parameters. These materials are valued in applications requiring radiation shielding, kinetic energy penetrators, or compact high-mass components where conventional metals cannot achieve the same performance in limited space.

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.
