TiAlCu2
metal· TiAlCu2
TiAlCu2 is a titanium-aluminum-copper intermetallic compound, part of the Ti-Al alloy family that combines titanium's strength-to-weight ratio with aluminum and copper additions to modify stiffness, damping, and thermal properties. This material falls into the research and development category of advanced intermetallics, where it is explored for aerospace and high-temperature structural applications where conventional titanium alloys or aluminum alloys reach their limits. The copper addition typically enhances damping characteristics and may improve machinability compared to binary Ti-Al phases, making it potentially valuable for vibration-sensitive or precision-engineered systems.

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.
