· TiSi

TiSi is an intermetallic compound combining titanium and silicon, belonging to the family of transition metal silicides. It exhibits ceramic-like hardness and stiffness with metallic electrical conductivity, making it relevant for high-temperature and wear-resistant applications. This material is primarily investigated in research and advanced manufacturing contexts rather than commodity production, with potential applications in aerospace, automotive, and thermal barrier systems where exceptional hardness and thermal stability are critical.

Export Control

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.
