It's weightier than you'd anticipate, surprisingly common, and can definitely add some decent weight for your haul if a person know what you're looking for.
The trick with zinc is usually that it usually hides in simple sight. It's rarely the "star" of the product; instead, it's usually the workhorse material behind the scenes.

How to Spot Zinc in a Pile of Rubbish
One of the funniest issues about zinc scrap metal is how often individuals mistake it regarding aluminum. At very first glance, they look pretty similar—both have got that silvery-gray end. But if a person pick them up, the difference is usually immediate. Zinc is usually significantly denser and heavier. If a person have two identical-looking brackets and one feels like a down while the other has its own real "heft" into it, you're most likely holding zinc.
Another dead giveaway could be the way it breaks. If you have a piece of die-cast zinc (often called "pot metal" within the trade) and you hit it with a hammer, it won't usually bend such as aluminum or copper mineral. Instead, it seems to shatter or snap with a crystalline, grainy glance at the split point. It's frail compared to other non-ferrous metals, that is a key characteristic to consider when you're sorting through a trash can of mystery parts.
Then there's the "magnet test. " Like almost all valuable scrap metals, zinc isn't magnet. If your magnet sticks, you're taking a look at steel or metal, probably with a thin zinc covering (galvanized). While galvanized steel is recyclable, it won't fetch exactly the same price since clean, solid zinc.

Construction sites are usually another prime place. Zinc is utilized heavily in roof covering and flashing because it's incredibly proof to corrosion. If you see a few gray, weathered metal strips coming off a roof that will don't rust yet have a gentle, matte finish, there's a great chance you've found some high-quality zinc.
Knowing the "Pot Metal" Confusion
In the scrap backyard, you'll often hear people use the term "pot metal. " This is usually basically a catch-all phrase for the combine of low-melting-point alloys, and zinc scrap metal is the primary ingredient. In the day, manufacturers might just throw what ever "pot" of leftover metals they had—zinc, lead, tin, aluminum—into a mold to generate cheap parts.
Today, while the alloys are more refined, the name stuck. If you take your zinc towards the yard, they may categorize it since die-cast or pot metal. It's essential to ask how they grade it because clean, real zinc sheets from a roofing project could be worth more compared to a mixed-alloy die cast part from a good old lawnmower engine. Knowing the distinction can help you negotiate the better price or even at least understand why your invoice says what does.
Cleaning Your own Scrap for Better Prices

If a backyard worker sees a lot of steel mixed into your zinc, they'll most likely "downgrade" your entire load to the price of iron or "dirty zinc, " which is a cheaper clean price. An easy screwdriver plus a pair of pliers may literally double your own profit on the heavy bucket associated with die-cast parts.
Also, watch out for lead. Sometimes old plumbing related or weights can look like zinc. Most yards check for this, but keeping your prospect separate from your zinc is just good practice. Lead is softer (you may scratch it with your fingernail) and even heavier than zinc.
