Electro Tech Machining was founded in 1936 in Long Beach, CA to serve the needs for the US Navy.  Originally a marine specialty group, ETM found our niche rebuilding military engines for the naval bases in California’s South Bay area.

Electro Tech Machining offers graphite, carbon-based products and EDM materials in block form and as precision machined parts.  The industries we serve include aerospace, heat treating, metallurgical, petrochemical, power generation, semi-conductor and EDM applications.  We maintain a large inventory of different graphite materials including Isostatic, Extruded and Molded ranging in properties and sizes.
