CDA 521 Technical Data
- CDA 521 is a copper-tin filler metal used for brazing ferrous alloys, such as steel. This alloy is typically used in furnace brazing of steels where use of pure copper is no permissible.
- CDA 521 has good wetting characteristics on ferrous based materials, particular steel in furnace brazing applications. Maximum strength and joint integrity are obtained where joint clearance falls within the range of 0.003in. – 0.005in. per side.

X-55
X-55 is a brazing filler metal with excellent gap filling capability and plasticity when in the molten condition. The alloy exhibits excellent strength and ductility while cooling from the liquid stage. The improved strength and ductility at elevated temperatures gives it the added advantage over nickel silvers in joining materials with dissimilar coefficient of expansion. The primary application is in the joining of carbides to steel holders.
Some of the key properties of Prince & Izant's high-temperature bronze alloys include excellent resistance to oxidation and corrosion, high melting points, good thermal conductivity, and excellent strength at high temperatures. These alloys are used in a variety of applications, including turbine blades, heat exchangers, and exhaust systems.
