· JVASP-74433· BeCoW

BeCoW is a beryllium-cobalt-tungsten ternary alloy that combines the lightweight properties of beryllium with the strength and heat resistance of cobalt and tungsten. This material family is primarily explored in research and specialized aerospace contexts where extreme strength-to-weight ratios and thermal stability are critical, though industrial adoption remains limited due to beryllium's toxicity concerns and manufacturing complexity. Engineers consider BeCoW for applications demanding exceptional performance at elevated temperatures where conventional aluminum or titanium alloys prove insufficient.

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.
