When recycling brass scrap, understanding its main components is key to determining its value and best recycling practices. Brass is a widely used metal alloy composed primarily of copper and zinc, making it highly desirable in the scrap metal industry. At Botany Scrap Metal, we accept a variety of brass scrap which is then processed for reuse in manufacturing and industrial applications.

Copper: The Dominant Component

The primary element in brass scrap is copper. Typically, brass contains anywhere from 60% to 85% copper, depending on the type of brass and its intended use. Copper gives brass its excellent conductivity, corrosion resistance, and malleability, which makes it a preferred material in plumbing, electrical components, and musical instruments.

Zinc: The Secondary Metal

The second major component of brass is zinc, which typically makes up 15% to 40% of the alloy. Zinc enhances the strength and hardness of brass while lowering its melting point, making the alloy easier to cast and shape. The proportion of zinc affects the color and properties of the brass—higher zinc content often results in a lighter yellow appearance.

Minor Elements in Brass Scrap

In addition to copper and zinc, brass scrap may contain small amounts of other metals like lead, tin, or aluminum. These metals are added to improve specific characteristics such as machinability or corrosion resistance. For example, leaded brass is commonly used for precision components due to its ease of machining.

The Importance of Sorting Brass Scrap

At Botany Scrap Metal, sorting brass scrap based on its composition is essential to maximizing its value. Different types of brass, such as red brass (high copper content) and yellow brass (higher zinc content), are separated to ensure proper recycling and reintroduction into the manufacturing cycle.

Why Recycle Brass Scrap?

Brass is highly recyclable without losing its properties, making it a sustainable choice for industries. Recycling brass scrap reduces the need for new raw materials, saves energy, and minimizes environmental impact. At Botany Scrap Metal, we are committed to helping our customers recycle their brass scrap efficiently and responsibly.
