Filit 6 is a cobalt-based electrode for surfacings against heavy corrosion, erosion and cavitation under heavy impact and shock load and high temperatures (800 - 1000 °C depending on the application). It is characterised by good thermal shock resistance abilities. It is ideal for sealing surfaces at gas, damp, water and acid armatures, valve seats on combustion engines, hot extruder nozzles and hot log shears.
