· TiB2

Titanium diboride (TiB2) is a ceramic compound combining titanium and boron, belonging to the class of refractory ceramics known for exceptional hardness and thermal stability. It is widely used in cutting tools, wear-resistant coatings, and high-temperature aerospace applications where conventional metals reach their performance limits. Engineers select TiB2 when extreme hardness, chemical inertness, and thermal shock resistance are critical—particularly in environments where oxidation resistance and dimensional stability at elevated temperatures outweigh the brittleness inherent to ceramics.

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.
