The Electric Materials Company

Electric Materials has been a leader in manufacturing commutator segments, v-bound commutators, glass banded commutators, and shrink commutators for various industrial applications for over 100 years. Our experience is second to none when it comes to refurbishing commutators. We can replace mica v-rings and work with v-bounded commutators, glass banded commutators, and external & internal shrink ring commutators. Depending on the design v-bound commutators can be re-insulated with new mica v-rings and steel parts. This involves repairing the mica segments between the copper bars, replacing the mica v-rings, reusing the copper bars, and adding in additional steel components. In addition to our commutator business we are a copper specialist dedicated to crafting tailor-made extruded, cast or forged profiles and busbar products that are dedicated to switchgear and control panels. Our busbars are not mere 'off-the-shelf' stock options. We offer the flexibility to custom design and build busbars to your exact specifications, in any shape / alloy / plating and configuration you need.
