The Differences Between Copper, Bronze, & Brass

Copper, bronze, and brass are all valuable metals when sold to a scrap metal recycling facility. These metals are used in various applications, from industrial machinery to home decor. Despite their similarities, there are some significant differences between these metals that are important to understand. In this article, we’ll explore the differences between copper, bronze, and brass, including their properties, composition, and applications. If you’re looking to sell scrap metal in the Greater Boston area, contact our team at Second Street Iron & Metal in Everett!

Appearance 

Although all these metals have a red/brown/orange color, they do have some distinctions. Copper always has a reddish-brown color, while brass can vary from yellow to red depending on the amount of zinc in the alloy. Bronze, on the other hand, has a darker, more brownish color than brass and can also have a slightly greenish hue due to the presence of copper oxide.

Strength

Bronze is the strongest of the three metals due to its tin constituent. It is frequently used in high-strength applications, including ship propellers, gears, and bearings. Brass is sturdy but less durable than bronze, making it ideal for musical instruments and plumbing fittings. Copper is the most malleable of the three metals and is frequently used for decorative items and electrical wiring because of its softness.

Composition

Copper is composed of pure metal, while brass is an alloy made from copper and zinc. Bronze is also an alloy, but it is made from copper and tin, with small amounts of other metals often added for additional strength and durability.

Corrosion Resistance

All three of these metals have good corrosion resistance, but bronze is the most resistant due to the tin it contains, which helps protect against rust and other forms of corrosion. Brass is also highly resistant to corrosion, making it a popular choice for plumbing and marine applications. Copper is less corrosion-resistant than bronze and brass, but it is still suitable for many applications without exposure to harsh environments.

Cost 

Copper is the most expensive of the three metals due to its relative scarcity and high demand in the electronics industry. Brass is typically less costly than copper but more expensive than bronze due to the higher cost of zinc. Bronze is the most affordable of the three metals, making it a popular choice for various applications.
