· Mo

Molybdenum (Mo) is a refractory transition metal prized for its exceptional high-temperature strength, high melting point, and excellent corrosion resistance in many aggressive chemical environments. It is widely used in aerospace engines, nuclear reactors, chemical processing equipment, and tool steels, where engineers select it over iron-based alternatives to enable operation at elevated temperatures or in demanding corrosive conditions without significant property degradation.

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.
