Inconel 625 (EOS IN625)
What is it?
Inconel 625 (EOS IN625) is a metal alloy selected for particular strength, temperature, weight or manufacturing needs.
Why would someone print it?
Printing may help create complex shapes or low-volume parts, but the complete finishing and inspection route still matters.
What should a beginner know?
- Confirm the exact machine, material settings and acceptance requirements.
- A material listing does not by itself qualify a production part.
What happens after printing?
Printed parts may need heat treatment, support removal, machining, finishing and inspection before they are accepted. Powder feedstock is often the largest consumable in LPBF economics — public powder price evidence, where records exist, is collected by alloy on its own page.
What is an alloy?
What does this mean? An alloy is a defined metal composition. Why does it matter? Composition, process settings and post-processing affect the finished part.

Technical material evidence
A solid-solution-strengthened nickel-chromium-molybdenum alloy chosen when the problem is chemistry, not temperature: it resists pitting, crevice corrosion and oxidizing salts far beyond stainless steels, which puts it in marine, chemical-processing and exhaust-adjacent service. Unlike 718 it needs no aging treatment to reach its rated strength, so as-printed behavior is closer to final behavior. The AM-specific catch: it is printable but powder-hungry (reactive, fine powder), and cost per kilogram dominates part economics — verify powder reuse policy in the quote, not just the machine.

Manufacturing considerations
- strong weldability
- work-hardens during machining
- corrosion-critical apps need solution anneal
