Copper brazing alloys are known for their excellent corrosion resistance, high electrical conductivity and high thermal conductivity, and are commonly used for brazing carbon and alloy steels, stainless steels, nickel and copper-nickel alloys. Copper alloys are malleable, properly wet iron, and exhibit excellent joint penetration. These alloys are primarily used for furnace brazing using a protective reducing atmosphere in the absence of flux. For metals containing oxides that are difficult to reduce, a flux may be required.

Cu (w) Cu-based Brazing Paste
Solidus-liquidus°C: 1083-1083
Brazing temperature °C: 1093-1149
Description:
Cu-w is a combination of tungsten (W) with low thermal expansion and copper (Cu) with high thermal conductivity. Thermal expansion can be adjusted to surrounding materials such as alumina and cove alloys. In addition, due to its good machinability, it can make parts of small and complex shapes.
Storage and expiration date
When you receive the solder paste, please store it in the refrigerator asap, and the recommended storage temperature is 2℃-10℃.
● Too high temperature will shorten its service life and affect its characteristics accordingly.
● Too low temperature (below 0℃) will cause crystallization and deteriorate the characteristics.
Under normal conditions, the validity period is 6 months
Note: After being taken out of the refrigerator, the paste should be allowed to "warm up" at room temperature (about 4 hours) before opening the cap.
