Farmers Copper Ltd. sustains a broad inventory of Manganese Bronze C67500 in rod form. C675 possesses good torsional properties and general corrosion resistance. Manganese bronze withstands exposure to dry gases, dilute alkalies, sulfides, and most organic solvents and acids. Though C675 has common resistance, contact with ammonia, mercury, and most chlorine gas should be avoided.
