Nickel Aluminum bronze alloys typically contain 9-11% aluminum and up to 6% iron and nickel. Increasing the aluminum content of bronze results in higher strength. The various types of nickel aluminum bronze alloys are a popular choice for industrial applications such as landing gear bushings and bearings for the aerospace industry, propeller hubs, wear rings, and hardware for the marine industry, a piping for vertical pump columns, firefighting and fire suppression systems, and seawater lift pumps for the oil and gas industry,hydraulic bushings for earth moving equipment, as well as many other applications. This is due specifically to the addition of nickel which improves the corrosion resistance of the already versatile aluminum bronze alloys. Iron acts as a grain refiner and increases tensile strength without diminishing its excellent ductility and toughness.
Typical Uses This alloy is used in parts that come in contact with salt water such as blades, propellers etc. C95800 / AB-2 offers superior salt water corrosion resistance. It also is resistant to cavitation and erosion. Along with the advantage of pressure tightness, this high strength alloy is excellent for welding. Common applications for such alloys are Marine Propellers, Covers for Marine Hardware, Ship Building, Marine Hardware, Bearings, Bushings, Valve Balls, Forming Dies for Roll Bearings, Hydraulic Bushings for Earth Moving Equipment, Valve Parts – Cryogenic, Piping for Vertical Pump Columns, Firefighting and Fire Suppression Systems, Seawater Lift Pumps, Piping Layout, Flanges and Fittings, Discharge Elbows, Cooling Loops for Power Plants, Bronze Valve Bodies, Piping Systems, Desalination Equipment, Tube Sheets, Circulating Pumps and Pump Shafts, Fasteners, Hardware for Cooling towers, Pickling Equipment, Valve Guides, Piston Guides, Valve Seats, Pump Fluid Ends, Glands, Worms, Worms Wheels, Hot Mill Guides, Hand Gun Recoil Mechanisms, Landing Gear Parts, Air Craft Components, Wear Plates, Welding Jaws, Landing Gear Parts, Glass Molds, Machine Parts, Sewage Treatment Applications, Valve Components, Bearings, Bushings, Valve Bodies, Gears, Piping for Vertical Pump Columns, Firefighting and Fire Suppression Systems, Seawater Lift Pumps, Piping Layout, Flanges and Fittings, Discharge Elbows, Cooling Loops for Power Plants, Bronze Valve Bodies, Piping Systems, Desalination Equipment, Tube Sheets, Circulating Pumps and Pump Shafts, Fasteners and Hardware for Cooling towers.
