Bronzes vs Brasses

Compared to bronze, brass is more malleable, making it ideal for applications that require a high level of formability. On the other hand, it also demonstrates a significantly lower melting point (900 degrees Celsius).

Other properties of brass include the following:

• Muted yellow/gold color (depending on the amount of zinc)
• High corrosion resistance (especially if it contains an above-average amount of manganese)
• Susceptibility to cracking from excessive stress
• Highly castable
• Above-average thermal conductivity
• Non-ferromagnetic (making it easier to separate for recycling)

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.

The Differences Between Bronze and Brass

The differences in material compositions between bronze and brass result in varying characteristics that make them suitable for different use cases. For instance, bronze’s higher level of resistance to saltwater corrosion makes it a better choice for ship components than brass, while brass’s exceptional workability and machinability make it more suitable for tubing and pole applications. Table 1 below outlines some of the major differences between the two materials.
