What is C95500 Nickel Aluminum Bronze?
C95500 nickel aluminum bronze is a high-strength cast bronze alloy used for demanding wear, bearing, marine, and industrial service. It is commonly called 955 bronze, 9D nickel aluminum bronze, or NAB in U.S. supplier catalogs.
C95500 is selected when standard bearing bronze does not provide enough strength, pressure tightness, corrosion resistance, or resistance to shock and wear. It is often reviewed for heavy bushings, gears, marine hardware, valve components, and pump parts.
