Alloying elements in the composition of BrOCSN3-7-5-1 alloy increase fluidity and density of the material, as well as reduce its tendency to liquation. BrOOCSN3-7-5-1 bronze is rather difficult to work under pressure, but it easily resists corrosion and can be cut. Bronze is used to produce fittings for general purposes.
Useful information and properties:
Heat treatment: No heat treatment
Alloy hardness: HB 10 -1 = 60 MPa
