What metals are part of bronze

Are you interested in what metals enter into the composition of bronze? Supplier KMZ offers to buy bronze any brand at economical price. Supplier guaranteed timely delivery at any address specified by the consumer.

The composition of the bronze

The chemical composition of the bronze is quite complex, but the main component is always tin. This gives the bronzes strength and resistance to atmospheric corrosion. Any bronze has a relatively low melting point. To change the color, improve finish and improve casting characteristics fluidity, linear and volumetric shrinkage, to bronze add metals such as lead, gold or silver.

Bronze consisted of copper, tin and small quantities of other metals such as lead, iron, aluminum, chromium and others. The amount of tin can reach 40 percent, but classic bronze alloy includes 10% Sn and 90% Cu. Alloys with plenty of tin are technically alloys. Manganese is added to bronze, used for propellers of ships because it resists the corrosion of salt water. Iron, Nickel, silicon and aluminum added for strength tools, because bronze does not spark when you experience shock loads.

The effect of different metals on the properties of bronze

This influence is manifested in the change of strength, thermal and electric conductivity bronze. If the alloy added tin the metal becomes more technological. Zinc improves the thermal conductivity, and is more effective than tin. Aluminium, manganese, Nickel and silicon in the composition enhance the strength characteristics of the alloy. The best way to increase electrical and thermal conductivity of bronze is to reduce the level of impurities. The presence of impurities and all common alloying elements, except for silver, reduces these indicators. Cadmium has the least impact on the electrical conductivity of the resulting alloy, with a consequent increase in exposure to zinc, tin, Nickel, aluminum, manganese. Although the thermal conductivity involves a variety of mechanisms, the addition of increasing amounts of the listed metals also reduce the conductivity. Zinc has very minor effect on the thermal conductivity of the alloy.
