Two Types of Metal, Ferrous and Non-Ferrous

When you talk about scrap metal, you will find two different types that are regularly known; Ferrous, and Non-Ferrous metals. In this article you'll understand the basic differences among these metals, how to determine right after for yourself, and some resources where to find them.

Ferrous Metals

We'll first discuss ferrous metal. Ferrous metal is mostly used for things like machinery, cars, engines, farm implements, and other uses for example appliances, like stoves refrigerators, washers, dryers, and freezers. Lawn mowers are usually made from a combination of both metallic and non-ferrous metals. Most of your own smaller push type mowers, generally speaking, the motors are usually made from aluminium (a non-ferrous metal); however , the deck and handle assembly are manufactured from ferrous metals.

How to Determine if the particular Metal You Are Looking at is Ferrous or Not

Two of the best ways to discern in case a piece of metal you are looking at is made of metallic metals or not are these: Really does a magnet stick to it? And, if it's an older piece of metal, is there any kind of rust on it?

Does a magnets stick to it?

The biggest ingredient in ferrous metal is iron, or metal ore, which is a very magnetic material. Therefore , if you always carry a magnet around with you, you'll know immediately if the piece of metal will be ferrous or not. Of course , there are exclusions to every rule, and stainless steel (another non-ferrous metal) is one of those conditions. Even though the main component for making steel itself is iron, high quality stainless steel has a high amount of nickel in it (another non-ferrous metal) and, therefore , a magnet will not stick to it.

Will there be any rust on it?

The second plus usually more common way to determine whether the particular metal you have just found is ferrous or not is if you can noticeably see any rust anywhere in the item. Rust will especially be more prevalent on any areas which were touching the ground. Obviously, if a well used piece of ferrous metal has been left out in the elements, it's usually covered in rust, as a rule. Non-ferrous metals do not rust. They do, however , sometimes oxidize. We'll discuss that later in this article.

Scrap Metal Buyers Should Always Have a Magnet

Non-ferrous metals (and there quite a few to discuss here) tend not to contain any, or only little traces, of iron, and thus aren't magnetic. If you are into scrap steel recycling or are thinking or starting a scrap metal business, your very best friends should be a magnet. I recommend using one that is on a chain, and one that has VERY strong magnetic cost, because that is what you'll see all the people at the scrap yards making use of. A weak magnet can sometimes mislead you, because you are strong, as well as the magnet is weak, you can contact it quickly and pull this away quickly, and think that there is a piece of non-ferrous metal when in fact the metal you just found is in fact ferrous metal. That is also the main reason that I recommend that your magnet should dangle from a chain, simply waving the magnet in front of a metallic piece of metal will cause the magnet to "sway" or be "influenced" by the ferrous metal in some way.

Non-Ferrous Metals

As opposed to its ferrous counter-top parts, non-ferrous metals, as mentioned previously, do not rust. However , some non-ferrous metals do oxidize. Oxidation could be the process where there is a layer created on the outside of a piece of metal. Aluminum is one metal in particular that tends to oxidize rather than rust. Interestingly enough, it is roughly the same process; nevertheless , with the lack of iron contained in the metal, the oxidation looks white and flaky as opposed to reddish and porous looking.

Here is a list of non-ferrous metallic that are the most commonly found:

Copper
Aluminum
Stainless Steel
Brass
Lead
Platinum
Where do You Find Copper?

As a rule, you'll usually find copper within plumbing and refrigeration type applications, like air conditioners, refrigerators, freezers. Even in like the small window type air conditioning units there is a fair amount of copper tubes there as well.

In approximately 2009, when the economy was really in a bad way, there was a rash of thefts, particularly large commercial air conditioning units. I was told one doctor's office got their air conditioning units stolen twice. Just as soon as the new units had been installed and replaced after being stolen the first time, they were stolen again! It became such a big problem that will scrap yards were required by law to stop taking aluminum/copper radiators (ACR's) all together without written proof of exactly where they came from, and how you came by them, if you were trying to take them in as scrap metal.

Where to Find Aluminum...

When it comes to aluminum, some of the very first things people think about is aluminum cans, siding from homes, plus door and window trim. Back in the 1960's and 70's aluminum it was popular to utilize for replacements windows, until the home window manufactures starting using vinyl. Nowadays there are people who still have aluminum doors and windows being replaced, so be on the lookout with regard to opportunities to take advantage of when it comes to getting that will sort of scrap aluminum.

There are many additional applications where aluminum is used, but one of the greatest resources I can advise a person to find it is motors. There are many components under the hood of a car which are made from aluminum. Most radiators and air conditioning condensers are made of aluminum. The particular casings for the alternator are made of light weight aluminum, and many intake manifolds are made of light weight aluminum, as well as anchoring hardware attached to the particular engine.

Another rich source for locating aluminum is lawn mower motors. Not all the parts on an electric motor are made from aluminum, therefore , that sort of a mix of both ferrous metals and aluminum in scrap metal terms is called "irony aluminum. "

Lately, there are some car manufactures that are furthermore using aluminum to make cars parts like hoods, doors, and vehicle tailgates from. When you bring in an automobile for scrap metal recycling, it would be a good practice to put a magnet to those various parts and see if sticks or not, because there is no sense in getting paid ferrous scrap metallic prices for non-ferrous scrap alloys.

What Are Good Sources to Find Stainless Steel?

The best resource that I have actually found for finding stainless steel is restaurants and the food industry. Health requirements require that restaurants use stainless-steel because of how it cleans up so well, and it is usually the germ-free environment. The health care business is another source where you'll find stainless-steel in high demand.

In the early part of this year, I had the fortune of being selected to haul off scrap steel for about 90 Burger King locations across North Carolina, they were installing a new drink fountains. We were hired to haul off the old soda fountain devices. In those machines and other various scrap metal items we delivered off were loads of copper and brass, and massive amounts of stainless-steel!

You must exercise some caution, however , when you're dealing with stainless steel. Sometimes the metal looks exactly like stainless steel, yet there is not enough nickel content inside it to make it stainless steel, so a magnet will stick to it. That is one greatest reasons for making sure that if you are going to be buying scrap metal, or trying to sell this to a scrap yard, you MUST have a magnet, or you'll pay a lot of for it, or make yourself look silly, not knowing your metal product.

Brass Resources...

When it comes to finding brass, the most typical application is going to be plumbing fixtures; things such as faucets, drains, and some plumbing plumbing. Valves and pumps are other good sources for finding brass. Mentioning back to the Burger King jobs all of us did, there were a lot of brass fixtures, valves and pumps that we introduced to the scrap yard.

How Do You Discover Lead?

The number one source that I know for finding lead is batteries.

Car batteries
Golf cart batteries
Backup computer batteries
Batteries from fork lifts
Large diesel truck batteries
I think you get the picture. The particular batteries contain large quantities of lead.

You must be cautious when working with batteries because there is "battery acid" in most electric batteries. Many scrap yards are cautious with accepting batteries. For example , where I bring my scrap cars, the particular battery must be removed before you can accept the car in; no exceptions!

I think Platinum Was Used for Jewelry?

Whilst that is true, platinum is used intended for jewelry, it is not exclusive to becoming utilized for jewelry. The most common place to find platinum eagle is actually in catalytic converters.

Once again, the law makers had to step up and put into place laws governing who are able to recycle or scrap catalytic converters. For a while there were car dealerships that were getting catalytic converters cut off their particular automobiles, dozens at a time, right on the particular dealership car lot!

The law observance agencies and law makers had to move quickly before more vehicle lots were hit. Now there are usually laws is place prohibiting scrap yards from buying catalytic converters unless the person bringing them in has documented proof of how the catalytic converter was obtained. Sometimes even the documented proof is not even good enough. In this case, the law makers were extremely proactive to try to protect business owners through would-be criminals because catalytic converters are very expensive to replace. Furthermore, they will bring a pretty penny at the scrap yard, if you have the right documentation which is.

So there you have it, a full report on scrap metal and the differences between ferrous and non-ferrous metals; how to tell them apart as well as some sources to find the most valuable types.
