DULLFOS® 15 is a high flow and penetration alloy, even at low temperatures. Mainly used in copper-copper welding. It is not recommended to use it with iron or nickel alloys. finds great application in the refrigeration sector, especially when the joint is subjected to a strong mechanical or thermal stress. Very appreciated also in electromechanical constructions for its great conductivity. Do not use in sulphide-saturated environments. Operating temperature of the joint between -70° and +150 °C.
