Superior Flux Superior No. 520B Chloride-Free, Inorganic Acid Flux
Categories:	Metal; Nonferrous Metal; Solder/Braze Alloy
Material Notes:	Specially formulated for Brass, Copper, mild stainless steel and non-ferrous alloys. Wide active temperature range. Low organic content. Completely free of Zinc and chlorides. High fluxing activity. Residues are completely water soluble. Description: Superior No. 520B is a water-based, water-soluble flux with extended temperature capability that begins to clean metals at room temperature. This inorganic flux is chloride-free and reaches peak activity at 260°C/500°F. Residues are non-hygroscopic and non-corrosive and will wash-off with water. Superior No. 520B is specially formulated for soldering radiators and industrial soldering applications involving mild stainless steel, Copper, and non-ferrous alloys. Since it contains no chlorides, Superior No. 520B will not discolor Brass due to de-zincification, and helps make post-solder metal finishing a quicker, cleaner process.
