· Ta12 Al8 Co4 C4

Ta12Al8Co4C4 is a refractory composite material combining tantalum carbide with aluminum and cobalt constituents, belonging to the family of advanced ceramic-metal composites designed for extreme-temperature applications. This material system is primarily explored in research and specialized industrial contexts where exceptional hardness, thermal stability, and wear resistance are critical; it is typically encountered in cutting tool inserts, high-temperature structural components, and wear-resistant coatings rather than commodity applications, offering advantages over single-phase carbides through enhanced toughness and damage tolerance via its multi-phase microstructure.

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.
