What Is Bronze?

Bronze is a metal alloy that primarily contains copper and 12% tin. Other elements—such as aluminum, arsenic, manganese, phosphorus, and silicon—are also added to yield different properties. These mixtures form some of the common bronze alloys, including:

·Leaded bronze

·Phosphor bronze

·Aluminum bronze

·Silicon bronze

·Manganese bronze

Properties of Bronze

Bronze contains several unique properties that make it highly suitable for applications ranging from works of art to computer electronics. Characteristics of bronze include:

·Reddish-brown color

·Hardness and brittleness (although typically it is less brittle than cast iron)

·Melting point of 950 degrees Celsius

·High resistance to corrosion from saltwater

·Exhibits low metal-to-metal friction

Applications of Bronze

Bronze’s characteristics make it suitable for use in functional and aesthetic applications, such as:

·Marine and fishing. Many boats and ships employ bronze fittings and propellers due to the material’s high corrosion resistance.

·Sculptures and musical instruments. Bronze’s dull-gold tone makes it a popular source material for sculptures and other artistic endeavors, such as bells and cymbals.

·Electrical connectors and springs. Some bronze alloys are particularly suitable for electrical applications due to their excellent electrical conductivity.

·Bushings and bearings. The material’s low metal-to-metal friction makes it suitable for high-stress environments, such as those experienced by bushings and bearings.
