· Oxide CMC· Nextel 720/Aluminosilicate

Nextel 720/Aluminosilicate is a ceramic matrix composite (CMC) combining alumina-silica fibers in an aluminosilicate matrix, processed via slurry infiltration and high-temperature sintering. This oxide/oxide system is used in aerospace thermal protection, industrial furnace components, and high-temperature engine applications where oxidation resistance and damage tolerance are critical. Unlike brittle monolithic ceramics, this CMC retains some load-carrying capacity after matrix cracking, making it suitable for cyclic thermal and mechanical loading in extreme environments.

Regulatory Screening

Environmental

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.
