TL; DR: In this blog, you will learn which metals FormAlloy’s DED systems can process and why metal choice matters.
What metals can you work with? At FormAlloy, this is the first question nearly every engineer asks, and the answer is simple: our systems process stainless steels, titanium alloys, nickel superalloys such as Inconel 625 and 718, cobalt-chrome, copper alloys, tool steels, refractory metals, and aluminum. We can also blend powders mid-build to create one part with two distinct materials. Here’s why that flexibility matters, and what the science behind it actually shows.
Why Does Metal Choice Matter So Much
A bridge and a spoon do not share the same material, and neither should two very different parts. A rocket nozzle needs to survive heat that would melt a car engine in seconds. A surgical tool needs to resist corrosion inside the human body for years. A mining drill needs to withstand constant grinding without cracking.
This is the real reason people ask what metals you can work with. They are not asking out of curiosity; the wrong material means a failed part. Our DEDSmart platform solves this by giving engineers the freedom to choose the right metal instead of settling for whatever a machine happens to support.
How Do Alloys Handle Extreme Heat
Nickel superalloys like Inconel 625 and 718 are widely used in high-temperature applications because they can retain important mechanical properties under demanding thermal conditions.
A 2026 review in Materials Science in Additive Manufacturing examined how laser additive manufacturing affects nickel-based superalloys used in applications such as aerospace engines and gas turbines. The researchers highlighted how rapid solidification, repeated thermal cycles, microstructural changes, and thermal stresses can influence cracking and the final mechanical properties of these alloys. This shows why controlling heat input and deposition conditions matters when producing nickel superalloy parts. This same focus on controlled metal deposition supports our Manufacturing Solutions.
Is Titanium Really Worth the Cost
Titanium costs more than steel, yet aerospace, medical, and defense companies keep choosing it. Why? Because it offers high strength at a relatively low weight and strong corrosion resistance.
A 2025 Lawrence Livermore National Laboratory study, published in Advanced Engineering Materials, examined Ti-5553 titanium microlattices produced through laser powder processes. Using in-situ X-ray imaging and electron microscopy, the researchers showed how melt pool size and cooling behavior influence the microstructure and strength of printed titanium lattices. Titanium’s performance is not luck; it comes from tightly controlling how the metal solidifies, layer by layer. That same focus on controlled processing supports the titanium work handled by our Services team.
Why Blend Powders in One Build
Why settle for one metal when a part could use two? A component often needs a tough, wear-resistant surface on the outside and a lighter, cheaper core inside. Splitting that into two separate parts adds welds, bolts, and weak points.
Functionally graded parts solve this by blending powders mid-build, shifting smoothly from one alloy to another inside a single, solid piece. A valve might start as stainless steel at the base and transition into cobalt-chrome at the tip, where wear resistance matters most, with no seams and no joints. This capability sits at the core of FormAlloy’s work, and you can see real examples on our About Us page.
How Do Studies Prove This Works
Does any of this hold up outside a lab? The research above says yes. A 2026 review of nickel-based superalloys shows how thermal cycles, heat input, and microstructural changes can influence cracking and mechanical properties during additive manufacturing. Meanwhile, a 2025 study on Ti-5553 titanium showed how melt pool size and cooling behavior affect the microstructure and strength of printed lattices. Different metals, same lesson: control the process, and you have greater control over the final part.
That lesson is why our answer to what metals you can work with stays broad instead of narrow. Copper alloys, tool steels, and refractory metals each have their own processing requirements and sweet spots. We track developments in metal additive manufacturing and share findings through our Insights section and News page.
Is Your Metal Ready for DED
Not every metal behaves the same way under a laser. Some alloys crack easily; others oxidize the moment they hit air. Start by identifying the stress your part faces daily: heat, wear, corrosion, or weight limits. From there, our team maps your challenge to a proven alloy or a graded blend of several, based on real-world data.
Frequently Asked Questions
What metals can you work with for aerospace parts?
Aerospace components typically use titanium alloys and nickel superalloys like Inconel 625 and 718, since both hold strength at extreme heat while staying relatively light. These metals also resist fatigue, which matters for parts facing constant vibration and pressure changes.
Can you mix two different metals in one part?
Yes. Blending powders during a build creates functionally graded parts that shift gradually from one alloy to another, giving engineers strength exactly where they need it without adding extra joints.
Why choose cobalt-chrome over stainless steel?
Cobalt-chrome resists wear far better than most stainless steels, making it a strong pick for parts facing constant friction, like valve seats or cutting edges. Stainless steel remains the more affordable, easier-to-machine choice for parts facing less abuse.
Do refractory metals work well with directed energy deposition?
Refractory metals like tungsten and molybdenum handle deposition well because DED offers tight control over heat input, which matters since these metals have extremely high melting points and can crack under sloppy processing.
Is aluminum too soft for demanding industrial parts?
Aluminum is lighter and softer than steel or titanium. However, it still performs strongly in parts where weight savings matter more than raw hardness, such as certain automotive and aerospace brackets.
How do you decide which metal fits a repair job?
We look at what damaged the original part first. Wear calls for a hard coating like cobalt-chrome. Corrosion calls for stainless or nickel alloys. Matching the fix to the original failure is the whole strategy.
