· Al

Aluminum (Al) is a lightweight, non-ferrous metal that serves as the foundation for numerous commercial alloys and is prized for its excellent strength-to-weight ratio, corrosion resistance, and thermal conductivity. It is extensively used across aerospace, automotive, construction, packaging, and consumer electronics industries—from aircraft fuselages and engine components to beverage cans, heat sinks, and structural frames. Engineers select aluminum when weight reduction, ease of fabrication, recyclability, and cost-effectiveness are priorities, though its lower stiffness and strength compared to steel typically limit its use in high-load bearing applications without alloying or composite reinforcement.

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.
