· Ti2B

Ti2B is an intermetallic compound in the titanium-boron system, forming a hard ceramic-like phase that combines titanium's lightweight properties with boron's reinforcing effects. It is primarily encountered as a reinforcing phase in titanium matrix composites and as a constituent in titanium alloys designed for high-temperature and wear-resistant applications. Engineers select materials containing Ti2B when extreme hardness, elevated temperature stability, and lightweight design are critical—such as in aerospace turbine components, wear-resistant coatings, and advanced composite systems—though Ti2B itself is typically a secondary phase rather than the primary engineering material.

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.
