High-strength aluminium bronze for the heaviest applications
CuAl11Fe6Ni6 is also known as Promet NiAp410 — in international standards, the material appears under the designation CC334G. The alloy offers higher strength properties than Promet NiAp210 and withstands greater surface pressures and loads. Typical applications include the same uses as NiAp210, plus the internal parts of high-pressure hydraulic fittings, drawing and bending tools, the stone-flange nuts of pulp-grinding machines, and other highly loaded components.
