MBI Graphite Electrodes

 

MBI Graphite Electrodes are a proven way to lower melting and refining costs. We supply three grades of electrodes, including UHP, to EAF melting furnaces, LMF ladle melt furnaces, foundry arc furnaces, slag refining operations and holding furnaces throughout North America.

Manufacturing of MBI Graphite Electrodes takes place at modern electrode plans that have achieved ISO 9002 certification. Quality controls in place at the factories, combined with our own quality inspections, insure that each electrode meets our customers' individual and specific requirements.

Our strategy, always, is to provide our customers with competitive values. Our suppliers provide us with preferential pricing and top quality electrodes. We pass these savings along to you. Experience shows that the low consumption rate of our electrodes, combined with competitive pricing, allows us to offer our customers some of the most cost-effective electrodes in the industry. 

NEMA-Compliant and Custom Machining

All electrodes supplied by MBI Graphite are machined to NEMA standards. In addition, we offer custom machining to meet individual customer requirements. Electrode diameters, lengths and pin/socket sizing can be custom-manufactured.
