Lucas-Milhaupt BRAZE 505 Carbide Brazing Alloy

Subcategory: Silver Alloy; Copper Alloy; Zinc Alloy; Nonferrous Metal; Solder/Braze Alloy

Material Notes:

Applications: Braze 505 readily wets nickel and iron base alloys. It is recommended for joining 300 Series stainless steel and will retard interface corrosion in most exposures for which the base metals are suitable. However, for joints on cupro-nickel exposed to salt water at elevated temperatures, zinc-free alloys such as Braze 559, 603, or 630 should be used to avoid joint failure by dezincification.

Because this alloy is cadmium-free, it can be safely used on food handling equipment and hospital utensils.

The presence of nickel in Braze 505 aids in the joining of small tungsten carbide inserts in cutting tools. In addition, it offsets joint interface brittleness caused by diffusion of aluminum into the brazing alloy, when joining aluminum-bronze to steel.

Characteristics:Braze 505 is very fluid at its flow point and will quickly fill long, narrow joints. Because it has the tendency to liquate (i.e., separate into low and high melting constituents) when heated slowly, this alloy should be heated quickly through its melting range.

Specifications:This filler metal conforms to the following specification-AWS A5.8 BAg-24, SAE AMS 4788
