Silver-flo™ products are mainly used for soldering the following materials: copper and copper alloys, including brass, bronze, nickel silver and aluminium bronze, steel (unalloyed and low-alloy steel, stainless steel). Silver-flo™ 55 and 56 are cadmium-free universal silver brazing solders with very good soldering properties. They have a low soldering temperature, a narrow melting range and therefore very good flow behaviour. As a universal silver brazing solder, Silber-flo™ 40 offers a good compromise between low silver content and increased working temperature. Silver-flo™ 302 has a broad melting range with medium flow properties. The ideal choice for applications where a wide soldering gap cannot be avoided.
