· ScAlCu2

ScAlCu2 is an intermetallic compound combining scandium, aluminum, and copper, belonging to the family of lightweight high-strength alloys with potential for advanced structural applications. This material is primarily of research interest rather than established in production, representing exploration into scandium-aluminum systems for aerospace and high-performance engineering where weight reduction and stiffness are critical. The addition of copper to scandium-aluminum matrices is investigated for its effects on mechanical properties and potential strengthening mechanisms, making this compound relevant to researchers developing next-generation aluminum-based alloys that exceed conventional aluminum's performance envelope.

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.
