The chemical composition of bronze alloys

The main components of bronze alloys: tin, aluminum, manganese, silicon, beryllium, iron, and a number of other elements. Tin bronzes mandatory alloying element is tin, tin — copper, aluminum, iron, manganese, chromium or Nickel. See a table:

The operational properties of bronzes

The main advantage of bronze is its high corrosion resistance, wear resistance, low coefficient of friction, good thermal and electrical conductivity. Bronze does not lose its consumer qualities at temperatures to -25°C cast tin bronze, produced products, working at very high pressure and in conditions of high friction.

Application

The casting of these bronzes have high strength, excellent anti-friction properties and good corrosion properties. These bronzes possess qualities such as high electrical conductivity, thermal conductivity and heat resistance. They are used in the manufacture of parts for work in particularly difficult conditions: gears, hubs, valves, gears for cranes and turbines, conveyor augers, bearings under high specific pressure and load. Due to its special characteristics (a large volumetric shrinkage, high oxidation during melting and pouring), these bronze are mainly used for casting parts with simple shapes.

Aluminum bronze

This is the most common of anhydrous bronzes. Such bronzes have good corrosion resistance in water, good resistance to damage under conditions of cavitation, as compared to the tin bronzes have reduced friction wear.
