In order to increase the mechanical properties of brass, nickel, manganese, iron, tin or silicon elements can be added to copper, apart from zinc.
In these alloys called special brass, the total amount of additional elements does not exceed 5%.
CW111C, A copper nickel silicon alloy, Low alloyed copper alloyCuproNSS is a copper alloy developed by Tough Copper AlloySuitable for applications requiring high mechanical properties along with good electrical and thermal conductivity.
