BeCr4W
metal· JVASP-74379· BeCr4W
BeCr4W is a complex beryllium-chromium-tungsten alloy that combines the lightweight properties of beryllium with the high-temperature strength and hardness of chromium and tungsten. This material is primarily of research and specialized industrial interest, valued in applications requiring the exceptional strength-to-weight ratio that beryllium alloys provide, particularly where thermal stability and wear resistance are critical and beryllium's unique advantages justify its cost and processing complexity.

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.
