What is Dairy Metal?

C97600 Nickel Silver Bronze, also referred to as dairy metal or dairy bronze, is a cast bronze alloy with a high machinability rating of 70. C976 Dairy Bronze contains 63-67% Cu, 3.5-4.5 % Sn, 3-5% Pb, 3-9% Zn, 1.5% Fe, 19-21.5% Ni, 1% Mn, and 0.15% Si. Since C97600 is heavily used in the manufacturing of valves fittings and gears for the dairy industry, it has become known as the dairy metal. The alloy was once called ASTM Alloy 11A, but that name is now discouraged.
