Profile: Ampere Metal Finishing Ltd. specializes in providing metal finishing services for a wide range of industries, including automotive, nuclear energy, military and aerospace. We are an ISO 9001:2000 certified company. All our metal finishing processes & services are designed to accommodate both high volume and small production runs. This provides a built-in flexibility of production requirements while maintaining a strict adherence to all specifications. We also have on-site facilities for designing and fabricating many of our own production racks, jigs & other necessary equipment. It allows us to design and fabricate a rack or jig specifically for a particular part configuration in order to ensure maximum productivity while minimizing or eliminating rack or jig marks. It also allows us to reduce first run production delays in many instances, since we can often fabricate the needed equipment in less time than an outside source. It eliminates or minimizes much of the down time related to equipment maintenance and repair. Our processes include black oxide, phosphate coatings, passivation, dry film lubrication, PTFE coating, metal cleaning, chemical conversion coating, priming & painting, clear coating and additional services. The black oxide process is a chemical conversion coating. The black oxide coating is produced by a chemical reaction between the iron on the surface of the ferrous metal and the oxidizing salts present in the black oxide solution. These oxidizing salts include penetrates, catalysts, activators and proprietary additives which all take part in the chemical reaction. The result of this chemical reaction is the formation of black iron oxide and magnetite, on the surface of the metal being coated. Black oxide has a range of unique properties and benefits that can be applied to a variety of industries. We use a hot alkaline aqueous black oxide process.
