Whether in everyday life or in high-tech environments, electrical and electronic devices simplify our lives. Without these literally billions of microprocessor-controlled devices, high-frequency circuits and low-power transmitters, neither cars nor airplanes, neither workshops nor hospitals, neither modern industrial plants nor offices are thinkable - not even a normal household.
Safety and Reliability for the Devices of Today and Tomorrow
But the growing number of these devices also poses a problem: Manufacturers have to make sure that the devices in a system are able to function without error in their intended electromagnetic environment. In other words: They have to ensure their electromagnetic compatibility (EMC). Studies show that EMC problems result in fatal accidents and billions of dollars in lost revenue annually. Consequently, legislation and regulations increase with the proliferation of electronic equipment and devices, with severe penalties for violations.
Oerlikon Metco’s E-Fill™ conductive filler solutions — a variety of composite powders such as nickel graphite, high purity nickel or gold clad composites — excel in electromagnetic and radio frequency interference (EMI/RFI) shielding applications and significantly reduce costs in electronic device applications.
Our customers include leading global EMI shielding material manufacturers, leading aerospace firms, and emerging technology firms. We offer rapid prototyping from concept to large tonnage production, and our flexible coating processes and controls enable a variety of cores that can be clad.
Industries / Markets Served
- Aerospace & IGT turbine component
- Mining & construction
Our conductive filler materials are produced as powders with a hydrometallurgy method — a controlled aqueous process that uses temperature and pressure in a hydrogen atmosphere to add successive layers or "densifications" of nickel on top of the core material until the desired product is complete. These homogeneously-coated metallic and non-metallic core materials exhibit low resistance electrical contact with superior corrosion and heat resistance:
- Abradable Powders for thermal spray coatings in aero and industrial gas turbine engines
- Carbide Powders for boiler pipes wear/corrosion resistance
- Electronic Materials for EMI shielding and conductivity applications in mobile phones and other devices
- Specialty Nickel Powders for electronic and automotive applications
- Powders used as welding Fluxes and in/for flux cored wires
