· Al6 Hf4

Al6Hf4 is an intermetallic compound in the aluminum-hafnium system, representing a research-phase material combining aluminum's light weight with hafnium's high melting point and refractory properties. This material family is primarily investigated for extreme-temperature structural applications where conventional aluminum alloys fail, particularly in aerospace and high-performance thermal environments where the trade-off between density and thermal stability is critical.

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.
