General Bronze Casting Alloy Comparison
GUNMETAL / RED BRASS ALLOYS : | |||||||||||||||
Gunmetal, also known as red brass in the United States, is the most durable of all metals for the plumbing industry and commercial water pipe applications.. Originally used chiefly for making guns, it was eventually superseded in this department by steel. Gunmetal, which casts and machines well and is resistant to corrosion from steam and salt water, is used to make steam and hydraulic castings, valves, gears, statues and various small objects, such as buttons. |

TIN BRONZE ALLOYS : | |||||||||||||||
Copper tin alloys or tin bronzes are known for their corrosion resistance. Tin bronzes are stronger and more ductile than red and semi red brasses. They have high wear resistance and low friction coefficient against steel. The tin bronzes are used in bearings, gears, piston rings, valves and fittings. Lead is added to tin bronzes in order to improve machinability and pressure tightness. Lead decreases the tensile strength and ductility of the tin bronzes, but the composition can be adjusted to balance machinability and strength requirements. High leaded tin bronzes are primarily used for sleeve bearings. These alloys have a slow fail mechanism that temporarily prevents galling and seizing. The slow fail mechanism works by lead seeping out of the alloy and smearing over the surface of the journal. |

NICKEL ALUMINIUM BRONZE : | |||||||||||||||
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. |

MANGANESE BRONZE : | |||||||||||||||
Manganese bronzes are the strongest and one of the most wear resistant alloys with high tensile strength, high yield strength, hardness and ductility similar to steel. In addition to their excellent mechanical properties, manganese bronzes are also corrosion resistant. Manganese bronze contains small percentages of manganese, iron, and aluminum and lead for lubricity, anti-seizing and bonding. Like the aluminum bronzes, they combine high strength with excellent corrosion resistance. Manganese bronze bearings can operate at high speeds under heavy loads, but require high shaft hardness and nonabrasive operating conditions.
The various types of manganese bronze used in aerospace, fastener, marine, and oil and gas Industries. Typical applications in these industries include landing gear parts, lead screw nuts, strut bushings, screw machine parts, bearings, bushings, gears etc. |
