A few ways to tell common metals apart before you get to the yard:

MAGNET TEST — ferrous metals like steel and iron are magnetic. Non-ferrous metals like copper, aluminum, and brass are not. This is the quickest way to separate the two categories.
COLOR — copper is reddish-orange and distinct. Brass is yellow-gold. Aluminum is silver-gray and lightweight. Stainless steel is silver but heavier than aluminum.
WEIGHT — aluminum is notably light for its size. Cast iron and steel are dense and heavy. Copper is heavier than it looks.
FLEXIBILITY — aluminum sheet bends easily. Steel takes more force. Copper wire is pliable but has a distinct weight to it.

When in doubt, our team can help identify what you've got at the yard.

The US recycles about 80 million tons of it every year.

One of the biggest benefits of recycling steel is that it never loses its quality when it's recycled. It can be melted down and reformed indefinitely, and comes out just as strong every time.

Fall is a good time to go through the garage, shed, and yard before everything freezes over.

A few things worth pulling out for a trip to the yard:
- Old water heaters being replaced before winter�
- Aluminum window and door frames from renovation work�
- Lawn equipment done for the season — mowers, tillers, edgers�
- Auto parts, batteries, and vehicles not going back on the road�
- Leftover steel or aluminum from summer projects�
- Copper wire or plumbing from remodeling work�
- AC units being swapped out before storage

Not sure if something qualifies? Here's a list we've put together of what is acceptable
Some restrictions may apply to copper and appliances in some locations. Please call with any questions.

October 2nd is National Manufacturing Day.

A lot of what gets manufactured in this country starts as scrap. A significant portion of the raw steel, aluminum, and copper going into mills and manufacturers comes from recycled metal dropped off at yards like ours.

You bring it in, we process it, it goes to a mill, and it becomes something new. Alter has been that part of the chain since 1898.

50 new gondola railcars are now part of the Alter Trading fleet—strengthening our transportation network and supporting the movement of recycled metal back into steelmaking.

Built by The Greenbrier Companies using SSAB Zero™ steel, these railcars represent more than an investment in transportation capacity. They are a tangible example of the circular economy in action.

The recycled steel used to produce the SSAB Zero™ steel for these railcars came from high-quality recycled metal processed by Alter Trading. SSAB transformed that recycled metal into SSAB Zero™ steel, and Greenbrier used it to manufacture the railcars that will now help Alter move more recycled metal to steel producers.

Recycled by Alter. Transformed by SSAB. Manufactured by Greenbrier. Back in service with Alter.

That’s the circular economy in action—and a powerful example of what’s possible when recycling, steelmaking and manufacturing come together.

We’re proud to collaborate with SSAB and Greenbrier on this project and to showcase what’s possible when recycling, steelmaking, and manufacturing come together.

Copper, brass and aluminum can look pretty similar when they’re dirty or coated. Here’s a quick way to tell them apart:

• Copper: reddish-brown when scratched
• Brass: yellow-gold
• Aluminum: silver and lightweight

Scratching a small patch can help you figure out what you're working with and make it easier to sort your scrap before drop-off.

Today is National Crush a Can Day!

This day reminds us how important it is to recycle aluminum cans, one of the most recycled materials in the U.S. In fact, aluminum is 100% recyclable and takes 95% less energy to make a new can from an old one. Yet, over a million tons still end up in landfills every year.

Recycling our aluminum cans contributes positively to the world and our local economy.
