Physical characteristics and typical applications of mechanic carbon: Carbon for application in sliding parts is fabricated with artificial graphite or amorphous carbon and it may contain synthetic resins or metals to improve its characteristics. These materials present many vantages which are no available in metallic materials normally used for the same purpose. Some characteristics are: […]
Compound obtained from the combination of cotton tissues imbued with synthetic resins, laminated under high pressure and temperature. It is used for structural purposes where the mechanic requirements are more important than the electrical ones. Celeron is a material which allows the production of extremely mechanical resistant parts, like gears, vanes, bearings for pumps and […]
Electrical contacts are products electric mechanics used in several electrical equipments, from high to low tension. Produced with alloys in cooper, brass, bronze (or another material according with customers needs) can be provided with silver applications or as required. – Sheets for commutation keys; – Mobile and fixed sheets for keys; – Mobile and fixed […]
Carbon for feeding systems of mobiles devices Carbon of great reliability to feed mobile devices in general, especially process cranes, electric hoists, monorails, etc. – Brass shoe gears for pantographs; – Graphite triangular contact – with nominal chain of 25A to 150A; – Graphite rectangular contact – force collector equipment.
Graphite plates, blocks and self lubricating scales which supports extremely high temperatures (until 3000°C). They are used to make plastic templates, manufactured moulds, stamp moulds, among others. Advantages of using graphite: – Easy to machining; – Excellent mechanic resistance; – Low thermal dilatation coefficient; – Excellent electrical conductivity; – Excellent surface completion; – Available in […]
Characteristics and typical applications of carbon brushes The graphite or the graphite compound +metals in electrical applications present some characteristics that make a difference from the compound normally used for the same aim. Some of those are: – High fusion point which avoid that the contacts merge even under the effect from the electric arc; […]
