metal

· JVASP-16080· Mn

Pure manganese is a brittle transition metal with significant hardness and wear resistance, widely employed as an alloying element in steels and cast irons rather than as a standalone structural material. In industry, manganese is primarily valued for strengthening ferrous alloys, improving their hardenability and impact resistance, while also serving in batteries, pigments, and chemical catalysts. Engineers select manganese-containing alloys over plain carbon steel when enhanced toughness, abrasion resistance, or magnetic properties are required, particularly in heavy machinery and demanding wear applications.

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.
