What is Bronze?

Bronze is made by smelting both copper and tin together. When bronze is used for casting statues, it contains approximately between two and 20% tin, while bells use a higher percentage of tin: 15-20%.

Additives are usually included when the bronze needs to be more workable, harder, or easier to cast. For example, phosphorous is added to harden bronze for use in tubing and other various machine parts, while lead is included to make bronze take more readily to casting.

Bronze has often been confused with brass, an alloy of copper and zinc, but the two alloys have different properties and are used for different things. Furthermore, bronze is much harder than brass.

Today's bronze composition may vary significantly, and contemporary bronzes are typically copper alloys which may contain silicon (Si), manganese (Mn), aluminium (Al), zinc (Zn), lead (Pb), iron (Fe) and other elements, either with or without tin (Sn).

The variations in bronze (both in proportion and elemental composition) can significantly effect its characteristics, whether it is providing a higher resistance to wear, better machinability, less corrosion in water, etc.

Since ancient times, bronze has been the most popular metal for casting statues and other art objects. It is preferred because of the uniqueness in which molten bronze becomes a solid. After the molten bronze is poured into a mold, it will expand as it cools and fills every small detail of the mold.

When it solidifies and cools further, it shrinks slightly so the final piece of art does not stick to the mold. With time, the bronze takes on a range of colours caused by oxidation of the surface, an effect that is called a patina.

All of the bronze emblems on our website are cast by one of the best manufacturer's in bronze products. Their quality and craftsmanship is detailed in every aspect. Our customers have been pleasantly pleased with the orders they have placed with us.
