· JVASP-67469· BeFeMo

BeFeMo is a beryllium-iron-molybdenum ternary alloy combining the lightweight and stiffness benefits of beryllium with the strength and toughness contributions of iron and molybdenum. This material family is primarily explored in aerospace and defense applications where extreme strength-to-weight ratios and thermal stability are critical; however, beryllium-containing alloys remain specialized due to manufacturing complexity and health/safety considerations in handling beryllium dust, making them suitable only when conventional alternatives cannot meet performance demands.

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.
