PROPERTIES
Density: 7,5–9,3 g/cm³,
Melting point: 940–1084 °C,
The most commonly used alloys: tin, aluminum, beryllium, silicon and lead. The name bronze comes from the main alloying additive.
Bronzes are divided into two groups, i.e. bronze for forming and foundry bronze.
Foundry bronzes are characterized by resistance to corrosion, abrasion and good machinability.
Molding bronzes are characterized by high durability, corrosion and abrasion resistance. Smaller amounts of alloying additives are used for foundry bronzes in order to obtain better plastic properties of alloys.
Foundry bronzes are often multi-component alloys containing, in addition to tin, other elements such as zinc, aluminum, lead and phosphorus.
Their structure consists of grains.
Foundry bronzes are known for resistance to corrosion, abrasion and good machinability.
