Step-by-Step Guide to Sorting Scrap Metal

Now, let’s get down to the nitty-gritty of sorting scrap metal. Follow these steps for optimal results:

**Step 1: Preparation and Safety**

* **Gear Up:** Put on your gloves, safety glasses, and work boots. Safety first!
* **Prepare Your Workspace:** Clear your designated work area and organize your tools and storage containers.
* **Assess Your Scrap:** Take a quick inventory of the scrap metal you have to get an idea of the volume and types of materials you’ll be sorting.

**Step 2: Initial Separation – Ferrous vs. Non-Ferrous**

This is the most basic and important separation. Ferrous metals contain iron and are magnetic. Non-ferrous metals do not contain iron and are not magnetic.

* **Use Your Magnet:** Hold your magnet over each piece of scrap metal. If it sticks, it’s ferrous. If it doesn’t, it’s non-ferrous.
* **Categorize:** Place ferrous metals in one container and non-ferrous metals in another.

**Examples:**

* **Ferrous:** Steel pipes, iron railings, car rotors, appliances (most parts are steel), nuts and bolts.
* **Non-Ferrous:** Copper pipes, aluminum cans, brass fixtures, stainless steel sinks, wires (usually copper inside).

**Step 3: Sorting Ferrous Metals**

Even within the ferrous category, there are different types of steel and iron that fetch different prices.

* **Steel vs. Cast Iron:** Cast iron is typically heavier and more brittle than steel. It often has a rougher surface. Look for markings or stamps that indicate the type of metal.
* **Light Iron:** This includes thin-gauge steel, such as sheet metal from appliances or car bodies. It usually fetches a lower price than heavier steel.
* **Heavy Steel (HMS – Heavy Melting Steel):** This is thicker, heavier steel from structural beams, pipes, and machinery. It commands a higher price.
* **Stainless Steel:** While containing iron, stainless steel is a valuable alloy due to its corrosion resistance. It is usually non-magnetic or only weakly magnetic. Test with a magnet; if it barely sticks, it’s likely stainless steel. Look for markings like “304” or “316.”

**Step 4: Sorting Non-Ferrous Metals**

This is where the real money is! Non-ferrous metals generally fetch significantly higher prices than ferrous metals.

* **Copper:** Copper is one of the most valuable scrap metals. It’s easily identifiable by its reddish-brown color. Common sources include pipes, wiring, and electrical components.
* **Bare Bright Copper:** This is the cleanest and most valuable type of copper. It’s uninsulated, uncoated, and at least 1/16 inch thick.
* **#1 Copper:** This includes clean copper pipe, tubing, and other copper pieces that are free of solder, paint, and other contaminants.
* **#2 Copper:** This includes copper pipe and tubing with solder, paint, or other minor contaminants.
* **Copper Wire (Insulated):** The price of insulated copper wire depends on the gauge (thickness) and the insulation material. Thicker wire with less insulation is more valuable. You can strip the insulation yourself to get a higher price for the bare copper, but factor in the time and effort involved.
* **Aluminum:** Aluminum is lightweight and silver-colored. Common sources include aluminum cans, siding, window frames, and car parts.
* **Aluminum Cans:** These are the most common and easily recyclable form of aluminum. Crush them to save space.
* **Aluminum Siding:** Clean aluminum siding fetches a good price.
* **Aluminum Wheels:** Car and truck wheels are typically made of aluminum alloy and are valuable.
* **Cast Aluminum:** This is a heavier, less flexible form of aluminum found in engine blocks and other automotive parts.
* **Brass:** Brass is an alloy of copper and zinc. It has a yellowish color and is often used in plumbing fixtures, hardware, and musical instruments.
* **Bronze:** Bronze is an alloy of copper and tin. It has a reddish-brown color and is often used in bearings, bushings, and sculptures.
* **Lead:** Lead is a heavy, soft, and malleable metal. It’s often found in batteries, weights, and plumbing. Handle lead with extreme care, as it is toxic. Wear gloves and a respirator when handling lead, and wash your hands thoroughly afterward.
* **Stainless Steel (Again):** As mentioned earlier, stainless steel is valuable even though it contains iron. Ensure it’s properly separated from other ferrous metals.
* **Zinc:** Zinc is a bluish-white metal often used for galvanizing steel. It’s found in gutters, downspouts, and die-cast parts.

**Step 5: Further Sorting and Preparation**

Once you’ve separated the main metal types, you can further refine your sorting to maximize your profits.

* **Remove Attachments:** Remove any non-metallic attachments from your scrap metal, such as plastic handles, rubber hoses, and electrical components. These attachments can lower the value of your scrap.
* **Strip Insulation from Copper Wire:** Stripping the insulation from copper wire can significantly increase its value. You can use a wire stripper tool or carefully cut the insulation with a utility knife. Be careful not to damage the copper wire.
* **Separate Alloys:** If you encounter alloys (mixtures of different metals), try to identify the components and separate them if possible. This can be challenging, but it can be worth the effort for valuable alloys like brass and bronze.
* **Clean Your Scrap:** Remove any dirt, grease, or other contaminants from your scrap metal. Clean metal fetches a higher price.
* **Crush Aluminum Cans:** Crushing aluminum cans saves space and makes them easier to handle.

**Step 6: Identifying Uncommon Metals**

Sometimes you might encounter metals that are less common and harder to identify. Here are a few examples:

* **Titanium:** Titanium is a lightweight, strong, and corrosion-resistant metal. It’s often used in aerospace and medical applications. It’s non-magnetic and has a dull gray color.
* **Nickel:** Nickel is a hard, silvery-white metal that is often used in alloys. It’s magnetic and has a high melting point.
* **Tungsten:** Tungsten is a very hard, dense, and heat-resistant metal. It’s often used in light bulb filaments and cutting tools. It’s very heavy for its size.
* **Precious Metals (Gold, Silver, Platinum):** These metals are extremely valuable and should be handled with the utmost care. They are often found in electronics, jewelry, and dental scrap. If you suspect you have precious metals, consult with a reputable precious metal refiner.
