It’s important to understand why Mallory and Elkonite® scrap often go unnoticed. These materials rarely appear as obvious bulk metal—they’re usually embedded in small components, worn parts, or electrical assemblies. Because of that, they’re easy to overlook or toss into mixed scrap.
The good news: you don’t need lab testing or deep material expertise to spot them—just a few practical cues.
Key Takeaways
- Mallory and Elkonite® are tungsten-based composite metals commonly used in electrical contacts and electrodes.
- They are typically dense, heavy, and silver-gray, often with a slightly matte or grainy finish.
- You’ll most often find them in contacts, welding electrodes, EDM components, and high-wear tooling.
- You don’t need lab testing—visual clues, application context, and weight are usually enough to flag them for recycling.
- If unsure, set it aside—don’t throw it out. These materials carry significant value.
What Are Mallory and Elkonite® Materials?
Mallory and Elkonite® are trade names for tungsten-heavy alloys, typically made from:
- Tungsten (W) – extremely dense, heat-resistant metal
- Combined with copper or silver for conductivity
Because of this, they’re used in electrical and industrial applications where standard metals would fail.
What Do Mallory or Elkonite® Look Like?
Are there visual clues you can rely on? Yes—and they’re surprisingly consistent.
Look for:
- Color: Silver-gray (not shiny like aluminum, not dark like steel)
- Finish: Slightly dull or matte, sometimes grainy
- Weight: Very heavy for their size (this is one of the biggest giveaways)
- Edges/Wear: May show pitting or wear from electrical contact
They often feel denser than steel when picked up—this is usually the fastest field test.
What Forms Do They Commonly Come In?
What shapes should you be looking for? Mallory and Elkonite® scrap rarely shows up as raw stock. Instead, they appear as finished components or worn parts.
Common forms include1:
- Electrical Contacts
- Small blocks, buttons, or inserts
- Found in switches, breakers, and relays
- Often attached to copper backings
- Electrodes
- Used in resistance welding or EDM (Electrical Discharge Machining)2
- Cylindrical, squared, or custom-shaped
- May show burn marks or erosion
- Tooling Inserts
- Wear-resistant tips or components
- Found in high-friction or high-heat tooling environments
- Contact Tips & Holders
- Used in industrial electrical systems
- Often brazed or mounted into assemblies
Where Are These Materials Found in a Facility?
Where should you look in your plant? These materials are usually tied to electrical or high-heat operations, not general machining scrap bins.
Check areas like:
- Maintenance departments (old contacts, spare parts)
- Welding stations (resistance welding electrodes)
- EDM machining areas
- Electrical panels or switchgear replacements
- Tooling storage or worn insert bins
They’re often overlooked because they don’t look like traditional “scrap metal.”
What Should You NOT Worry About Identifying?
Do you need exact grades or composition? No—and this is where many facilities overthink things.
You do NOT need to:
- Know the exact alloy percentage
- Separate Mallory vs. Elkonite® precisely
- Perform chemical or lab testing
- Clean or process the material
For recycling purposes, the key is simply:
Recognizing that it’s a dense, tungsten-based contact material and keeping it separate. Even mixed lots are valuable when properly identified.
How Can You Quickly Tell If It’s Worth Saving?
Ask yourself:
- Is it unusually heavy for its size?
- Did it come from an electrical or heat-intensive application?
- Does it look like a contact, electrode, or insert?
If the answer is yes to any of these:
👉 Set it aside. You can sell it to specialty buyers for a premium
Why Proper Identification Matters
Mallory and Elkonite® materials contain tungsten and other high-value metals, which:
- Command higher prices than standard scrap
- Are often missed or discarded unintentionally
- Can open the door to broader rare metal recycling programs
For many facilities, identifying even a small stream of this material can become a new revenue source with zero additional production effort.
When in Doubt, Separate It
You don’t need to be perfect—you just need to be aware.
The biggest missed opportunity isn’t misidentifying Mallory or Elkonite®…it’s throwing it away without realizing what it is.
If something feels dense, looks like a contact, and came from a high-heat or electrical process, it’s worth a second look.
