· JVASP-65250· TaBeNb

TaBeNb is a refractory metal alloy combining tantalum, beryllium, and niobium, designed to withstand extreme temperatures and harsh chemical environments. This material is primarily investigated for aerospace and high-temperature structural applications where conventional superalloys reach their performance limits, offering potential advantages in ultra-high temperature service and oxidation resistance.

Regulatory Screening

Environmental

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.
