Carbon and low-alloy steels fit structural applications, stainless grades deliver corrosion resistance, while tungsten and copper address density and conductivity.
Superalloys offer high-temperature and creep resistance, benefiting aerospace and medical applications.
Feedstock customization
AMT tunes powder, binder, and process windows to project needs, studying particle morphology, rheology, and debinding behavior to hit targets for strength, magnetism, and thermal performance.
Resulting properties
The result is dense, reliable parts with tuned tensile, magnetic, and thermal properties. Alloy choice and heat treatment refine corrosion resistance and long-term durability.
Testing & consistency
Each batch is verified via microscopy, density checks, and mechanical testing to meet specifications and standards.
Material selection support
AMT engineers help choose between carbon steels, stainless, tungsten, superalloys, or custom mixes, balancing cost, manufacturability, and long-term performance.
