· AlFe

AlFe is an aluminum-iron intermetallic compound or aluminum-iron based alloy system. This material family bridges the properties of lightweight aluminum with the strength and stiffness contributions of iron, positioning it between conventional aluminum alloys and higher-density steel alternatives. AlFe compositions are of interest in structural applications where weight reduction and moderate-to-high stiffness are competing demands, though commercial adoption remains limited compared to established Al-Cu, Al-Mg, and Al-Si systems.

Regulatory Screening

Environmental

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.
