Magna-Tech Chromate Conversion Coatings
Magna-Tech Manufacturing offers Iridite Conversion Coating, also known as Chromate Conversion Coatings. Conversion Coating is conductive and is designed to improve corrosion resistance for unpainted aluminum surfaces as well as increase adhesion of paint finish for aluminum and aluminum alloys.
Magna-Tech's Conversion Coating qualifies under Military Specifications. Our process classifies under MIL-C-5541E, which includes protection against corrosion on painted or unpainted surfaces and also protection against corrosion where lower electrical resistance is required. This Conversion Coating process is approved in the aerospace and electronics industries.
Magna-Tech's process provides an economical solution for corrosion prevention. Additionally, we supply fast turn-around for this service.
Enviroseal provided by Magna Tech is effective for wires, wire harnesses, terminated connectors, thermistors, over-molded coil windings, and insert and injection mold components that are exposed to harsh environmental conditions. The sealing process ensures part integrity. There is no change in the appearance or dimensional attributes of the components.
Casting impregnation sealing at Magna-Tech Manufacturing is most effective on porous substrates such as metal castings and powdered metal components required to meet pressure retention specifications, or to improve machinability or finish quality of the part. Candidates for impregnation include parts manufactured to contain gases or liquids and parts that will be plated or coated with a surface finish. Parts can be impregnated in the as-cast or in the machined state.
The Vacuum Pressure Impregnation process takes place after the stator has been wound and the bracing system installed. VPI is the process developed for impregnation of the windings with epoxy resin that gives the premium epoxy system its unmatched quality. Epoxy resins are ideal as impregnants because, in their cured solid state, they are extremely tough, with excellent resistance to both moisture and practically all types of chemical contaminants encountered in normal motor application environments.

Magna-Tech Manufacturing offers processes to remove rust and corrosion from ferrous materials. Production parts that cannot be used, or may be considered scrap due to corrosion, are candidates for Magna-Tech’s de-rusting services.
Magna-Tech Manufacturing provides Thermal Deburring services for applications that typically have inaccessible burrs such as internal and external flashing burrs, rough edge finishes and applications that have threaded holes.

Shipping containers often become contaminated from repeated use or from machining oils and other debris. Magna-Tech provides dunnage washing services to clean these contaminants from shipping materials. We utilize a fully automated system to provide fast and cost-effective service.
During casting, at least some of the hardening atoms remain in solution. If the part is elevated in temperature, the rate of nucleation and growth of these precipitates can be accelerated. This treatment is called artificial aging (T5) and improves strength through precipitate hardening. Some T5 treatments are performed for the purposes of stabilization rather than improving strength.
