Nickel bronze is Wade's name for C99700 white manganese brass. Its tensile strength ranges from 40,000 to 60,000 pounds per square inch. This particular material maintains its appearance despite abuse or exposure. Nickel bronze is preferred to chromium plated brass whenever lasting appearance is required and should be used in all finished floor applications. Loading is applied slowly so that point of failure can be observed.
Point of failure is established for cast iron or ductile iron when the first fracture appears.
