APD makes as well high resistance brasses or high tensile brasses. Addition of manganese, nickel or silicon has the effect of improving the mechanical properties and yield strength. These alloys offer a good friction characteristics and good marine corrosion resistance. Typical parts include bushes, rings, valves, hydrauling fittings,...
