· B2 Ta4

B2 Ta4 is a tantalum-based intermetallic compound with a body-centered cubic (B2) crystal structure, representing a phase in the tantalum binary or multicomponent system. This material is primarily of research and development interest rather than an established commercial product, with potential applications in high-temperature structural applications where tantalum's refractory properties and oxidation resistance are leveraged.

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.
