ceramic· JVASP-18899· AlO3
Aluminum oxide (Al₂O₃), commonly known as alumina, is a hard ceramic compound widely used in engineering applications where wear resistance, electrical insulation, and thermal stability are critical. It is the primary constituent of corundum and serves as the base material for abrasives, refractories, and advanced ceramics across aerospace, electronics, and manufacturing industries. Engineers select alumina for its exceptional hardness, chemical inertness, and ability to maintain performance at high temperatures, making it a preferred choice over softer ceramics and polymers in demanding structural and functional applications.

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.
