Al2 O3
ceramic· Al2 O3
Aluminum oxide (Al₂O₃), commonly known as alumina, is a ceramic compound that is one of the most widely used technical ceramics in engineering. It is valued for its combination of hardness, chemical inertness, electrical insulation, and thermal stability, making it a workhorse material across multiple industries where metal or polymer alternatives cannot meet demands for wear resistance, high-temperature performance, or electrical properties.

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.
