Overview
Magnetic epoxy glass laminates combine glass cloth, iron powder and epoxy resin to provide magnetic conductivity alongside high electrical resistivity and mechanical strength. They are specialist materials for motor slot wedges and related electrical-machine components. MaterialCut coordinates cut-to-size supply and confirms the required grade, thickness and drawing before quotation.
