How to Tell What Type of Scrap Metal You Have Before You Sell

One of the biggest questions people have before bringing in scrap metal is whether they actually know what they have. It is common to have a mix of materials collected from a garage, jobsite, or renovation project, and without a clear understanding of the types of metals, it is easy to miss out on value. At Scrap Mart Metals, we help customers identify their materials every day, but having a basic idea before you arrive can make the process smoother and more rewarding.

A simple starting point is using a magnet. This is one of the easiest ways to separate ferrous metals from non ferrous metals. If a magnet sticks, the material likely contains iron and falls into the ferrous category, such as steel or cast iron. If it does not stick, you are likely dealing with a non ferrous metal like aluminum, copper, or brass, which typically brings higher value.

Color and weight can also give you clues. Copper has a reddish tone and is heavier than it looks. Brass has a yellow or gold appearance and is often found in plumbing fixtures. Aluminum is lighter and has a more silver color. Stainless steel can sometimes look similar to regular steel but does not rust as easily and often feels slightly heavier.

Where the material came from is another helpful indicator. Electrical wiring is usually copper. Plumbing materials often include copper or brass. Window frames and siding are commonly aluminum. Appliances and structural materials are often steel. Thinking about the original use of the item can point you in the right direction.

While these guidelines help, you do not need to be an expert before bringing in your scrap. At Scrap Mart Metals, our team will help you identify and sort your materials so you get the most value possible. The goal is to make the process simple while ensuring you are paid accurately for what you have.
