BeFeCu4
metal· JVASP-65004· BeFeCu4
BeFeCu4 is a beryllium-iron-copper quaternary alloy combining the lightweight and stiffness benefits of beryllium with iron and copper to improve strength, conductivity, and workability. This material family is primarily investigated for aerospace and electronics applications where the combination of low density, high elastic modulus, and thermal/electrical conductivity offer advantages over conventional aluminum or titanium alloys, though beryllium-containing materials require careful handling due to toxicity concerns and are less common than established alternatives in production environments.

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.
