    Nicrobraz® nickel-based brazing pastes for SCRs, DPFs, EGRs, Catalytic Convertors, Fuel Cells and Heat Exchangers

    Reducing Emissions & Improving Fuel Economy

    Wall Colmonoy manufactures Nicrobraz® nickel-based brazing products, which are used extensively in the manufacture of Selective Catalytic Reduction (SCR) with DPF (Diesel Particulate Filler), Exhaust Gas Recirculation units (EGRs), Catalytic Converters, Fuel Cells and Heat Exchangers for aerospace, automotive and HVAC industries. All of these applications reduce emissions and improve fuel economy.

    With today’s tighter worldwide emissions, Selective Catalytic Reduction (SCR) is the latest advancement in reducing emissions for diesel engines.  SCRs for diesel engines convert Nitrous Oxides (NOx) into Nitrogen (N2) and Water (H20).  It often works with a Diesel Particulate Filter (DPF) which removes diesel particulate matter or soot from the exhaust gas of a diesel engine.  Soot is produced when diesel engines burn fuel, but a DPF captures this soot to prevent the release of harmful exhaust emissions.

    EGRs are also commonly deployed in diesel engines to reduce the concentration of NOx.  EGRs are usually brazed under high vacuum conditions using nickel-based filler metals to achieve good metallurgical bonding. Read about Nicrobraz® and EGRs in Nicrobraz News Issue.

    A catalytic converter is an emissions control device that converts toxic gases and pollutants in exhaust gas to less toxic pollutants by catalyzing a redox reaction (an oxidation and a reduction reaction).

    The world’s major automotive manufacturers and suppliers have selected Nicrobraz® as the nickel brazing filler metal of choice for the manufacture of their diesel engines and components.
