Brazing of copper tubes with copper, red copper cast and brass fittings in cold and hot water installation, gas installation, refrigerating and air conditioning applications. Alloy (weight %) 94% Cu, 6% P Melting temperature 710–890°C (1310–1640°F) Universally applicable for almost all types of joints in copper pipe installations. Specially useful for capillary brazing joints of copper pipe installations without fittings. Wide melting range due to low phosphor content result in higher toughness of soldering joint. Silver-free, complies with standards.
