This is a standard copper brazing alloy used extensively for brazing steel, stainless, and nickel alloys in a controlled atmosphere furnace. Offers exceptional strength and flow characteristics.

#110 is a free-flowing, high strength brazing alloy for the brazing of steel, stainless and nickel alloys. Brazing is performed in a controlled atmosphere environment without the use of flux. By controlling the moisture content (dew point) of the atmosphere, assembled parts exit the furnace clean and ready for shipment.

#110 is available in a variety of preform options and is well suited for tight fitted as well as press fit joints. From an economy standpoint, #110 is the least expensive brazing alloy available. With properly designed joints, it is also one of the strongest.
