High purity copper brazing alloy for furnace and vacuum brazing. Provides outstanding strength on steel, stainless, and nickel alloys. This brazing alloy provides high liquidity so it works great with tight fitting parts.

#102 is an oxygen-free, highly liquid brazing alloy. It is ideal for steel, stainless and nickel alloys. Brazing is performed in either a controlled atmosphere or a vacuum. #102 delivers superior strength (in excess of 75,000 PSI for properly designed joints) and is very ductile. Available in a variety of brazing preform options, #102 is best suited for press-fit joints. This makes it possible to produce high strength components with a minimum amount of braze alloy.
