Ferrous vs. Non-Ferrous Scrap Metal Recycling

In recycling, metal items are processed differently depending on whether they are made of ferrous or non-ferrous metal. While many waste disposal services will sort your scrap metal for you, understanding the difference between these types of metals as well as where they can be found can help you maximize the value of discarded materials.

In this article, we delve into ferrous vs. non-ferrous scrap metal recycling, exploring the unique properties and characteristics of each metal type as well as how they’re recycled.

What are ferrous metals?

Ferrous metals contain iron and are highly regarded for their tensile strength and exceptional durability. Their inherent strength and reliability make them indispensable in various demanding applications, from construction to cookware.

Examples of ferrous metals

While there are many different types of ferrous metals, the most abundant, valuable and commonly recycled ferrous metals include:

Steel: Widely recycled for its strength and versatility, steel is used in various industries such as automotive and construction.

Cast Iron: With its heat retention and wear resistance, cast iron is often recycled from sources such as pipes, machinery and cookware.

Wrought Iron: Known for its malleability and decorative appeal, wrought iron can be recycled from fences, gates, railings and other similar ornamental structures.

Characteristics of ferrous metals

Ferrous metals possess certain characteristics that make them well-suited for the recycling process, such as:

Magnetic Properties: One of the distinguishing features of ferrous metals is their magnetic nature, which allows for efficient separation and sorting.

High Density: Ferrous metals, such as steel and cast iron, have relatively high densities. This distinctive trait aids in sorting and separating ferrous metals from lighter, non-ferrous materials like aluminum.

High Carbon: Due to their high carbon content, most ferrous metals — with a few exceptions — are more susceptible to rusting. Wrought iron, however, contains a significantly high amount of iron, making it more resistant to corrosion, while stainless steel contains chromium to protect it from rusting.

Commonly recycled ferrous metal sources

Ferrous metals can be found in a variety of common appliances and sources, including:

Automobiles: Junked vehicles are a significant source of ferrous metals. The frames, engine blocks, suspension components and other parts of cars can contain valuable steel and cast iron.

Construction Sites: Ferrous structural steel beams, rebar, pipes and other metal components used in buildings and infrastructure projects can also often be recycled.
Household Appliances: Refrigerators, washing machines, dryers, stoves and dishwashers often have steel or cast iron components that can be recycled.
Industrial Machinery: Various types of industrial machinery, such as manufacturing equipment, conveyor systems and machine parts contain ferrous metals. When these machines reach the end of their life cycle or undergo upgrades, the ferrous components can be recycled.

Demolition Materials: When buildings or structures are demolished, the resulting debris can often be recycled, such as steel beams, columns and pipes.

What are non-ferrous metals?

Non-ferrous metals do not contain iron. These metals are valued for their malleability and light weight, making them helpful in a variety of industries, including aerospace engineering and electronics.

Examples of non-ferrous metals

There are plenty of non-ferrous metals, but some of the most common you’ll find are:

Aluminum: A lightweight and corrosion-resistant metal that can be recycled repeatedly without degrading its quality.

Copper: Commonly used in electrical wiring, plumbing systems and electronic components.

Brass: Commonly used in musical instruments, plumbing fixtures, decorative items and electrical connectors.

Characteristics of non-ferrous metals

Non-ferrous metals have a few highly beneficial qualities, including:

Corrosion Resistance: Non-ferrous metals such as aluminum, copper and zinc have excellent corrosion resistance. This property contributes to their durability and longevity, making them highly desirable for recycling.

Conductivity: Many non-ferrous metals including copper and aluminum are known for their electrical and thermal conductivity. The high conductivity of these metals enhances energy efficiency and allows these materials to be recycled for sustainable use.
Lightweight: Metals such as aluminum and titanium are significantly lighter than ferrous metals. This characteristic makes them valuable in industries like aerospace and automotive engineering that require lightweight materials.

Commonly recycled non-ferrous metal sources

Non-ferrous metals can be found in a wide range of sources that are commonly recycled, including:

Beverage Cans: Aluminum beverage cans are widely recycled due to the high demand for recycled aluminum. These cans are collected and processed to recover the valuable aluminum content, which can then be used to produce new cans or other aluminum products.

Electrical Wiring and Components: Copper is a highly sought-after metal often found in the electrical wiring, cables and components of motors and transformers.
Plumbing Fixtures: Plumbing systems and fixtures, such as pipes, faucets and valves, often contain copper and brass.

Automotive Parts: Non-ferrous metals can be found in various automotive parts, including radiators, catalytic converters and aluminum wheels. Recycling these parts helps recover materials and reduces the demand for new production.
Electronics: Electronic devices, such as smartphones, computers and circuit boards, contain non-ferrous metals like copper, gold and silver. Recycling electronic waste (e-waste) ensures the extraction of valuable metals and reduces environmental pollution caused by improper disposal.

Industrial Scrap: Industrial manufacturing processes generate a significant amount of metal scrap. This includes scrap from machining operations, metal fabrication and metalworking industries.

What is the difference between ferrous and non-ferrous metal scrap?

While there are notable differences between ferrous and non-ferrous metal scrap, including their value and how they’re processed, the most crucial aspect is that both types are recyclable.

Recycling metal scrap, whether ferrous or non-ferrous, reduces the demand for raw materials, conserves energy and minimizes the environmental impact associated with metal extraction and production. According to the Bureau of International Recycling, steel scrap recycling rates reached approximately 630 million metric tons worldwide in 2019.

Embracing efficient and sustainable metal recycling practices is crucial for those that value resource preservation and environmental responsibility.

How are ferrous and non-ferrous metals processed for recycling?

Whether you’re looking to recycle small or bulky items, the metal recycling process at Txalloy begins by separating the scrap metal into ferrous and non-ferrous types.

Reusable parts are then sorted and sold, while the remaining metals are cleaned to remove impurities.

The metals are then either crushed and baled or shipped to the mill, where they are melted in a furnace and transformed into metal sheets, rebar or cast into molds.

Selling your scrap metal: What is worth more, ferrous or non-ferrous metals?

The value of scrap metal, whether ferrous or non-ferrous, depends on various factors, such as location, market demand, quantity and current market conditions. In general, non-ferrous metals tend to have a higher value than ferrous metals due to their unique properties and higher market demand. Metals like copper, aluminum and brass are often more valuable due to their higher recycling rates and widespread use in the construction, tech, and automotive industries.

To get a better idea of current market prices, it’s recommended to contact local scrap yards or recycling centers and ask about their pricing structure for ferrous and non-ferrous metals.

Additionally, keeping an eye on commodity market trends and metal price indexes can provide insights into the overall direction of metal values.
