Hausmannite, also known as Manganese Tetraoxide or Mn3O4 powder, is a brownish-black or reddish-brown powder widely valued in the welding consumables industry. With unique physical and chemical properties, it is used as a key additive in welding electrode coatings and submerged arc welding (SAW) flux. Its stability and controlled reactivity make it superior to other manganese oxides in improving weld quality and performance.
Quality Commitment
Our Mn3O4 is manufactured under strict quality control measures to ensure consistent performance.
Each Tri Manganese Tetraoxide batch undergoes rigorous testing to ensure suitability and superior performance for intended applications. Our modern laboratories and experienced technicians guarantee dependable supply and repeatable results for customers worldwide.
Unlike other manganese oxides, Hausmannite (Mn₃O₄) delivers the ideal balance of stability and reactivity needed in welding electrodes and SAW flux formulations.
Controlled Reactivity: Unlike MnO₂, which can release excess oxygen and cause porosity, Mn₃O₄ provides a steady, controlled supply of manganese to the weld pool.
Enhanced Weld Quality: It improves slag fluidity and detachability, stabilizes the arc, and reduces spatter resulting in cleaner welds with excellent bead appearance.
Stronger Mechanical Properties: By optimizing manganese pickup, Mn₃O₄ strengthens weld metal, improving toughness and resistance to cracking.
Reliable Performance: More effective than MnO, Mn₃O₄ actively deoxidizes while maintaining thermal stability, ensuring consistency across applications.
For electrode and flux manufacturers, this means fewer weld defects, smoother operations, and higher-performing consumables.
Beyond welding, we also offer Manganese Tetraoxide Weighting Agent for Oil Drilling and Oil Well Cementing and Manganese Tetraoxide (Mn3O4) for Brick Coloring Pigment applications.
