CuZn39Sn

Category 
type 
Universal brass brazing alloy with good strenght
applications 
Brazing: Steels, Copper, Cast iron, Copper alloys, Nickel and for welding Brass and Bronze. This alloy is mainly used in the furniture and the bicycle industry for joining steels, also this alloy can be used for rebuilding Brass- ship propellers by flame welding.
Properties 

Easy to use brass alloy for brazing with separate flux or by using gasflux (flux transported by the flame), good mechanical properties and high corrosion resistance. Due to the components Fe, Mn and Sn. this type is the so cold “low fuming bronze”
