# Domestic Metal Powders Amaero Unveiled Its U.S. EIGA Alloy Powders Production By Adam Harrie | Written with AI assistance | Published 2026-08-29 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/alloy-powders References: [3dprint](https://3dprint.com/330970/amaero-builds-u-s-metal-powder-capacity-for-additive-manufacturing/) & [amaeroinc](https://amaeroinc.com/)  Amaero expanded metal powder manufacturing in the U.S., producing titanium and refractory alloy powders at its facility in McDonald, Tennessee. The operation uses Electrode Induction Gas Atomization systems to create highly spherical feedstock for [metal additive manufacturing](https://www.trendhunter.com/trends/Factory-scale-metal-printing) and other advanced manufacturing processes. Amaero now operates three EIGA atomizers, including two for titanium and one for refractory alloys, providing annual capacity of about 480 metric tons of titanium alloy powder and 200 metric tons of refractory alloy powder. The company has also supported America Makes-backed work through partner ADDMAN to qualify C103 niobium alloy powder for high-temperature applications and is working with ASTM International on Ti-6Al-4V powder production, including yield and recycling improvements. Beyond AM powders, Amaero uses [powder metallurgy hot isostatic pressing](https://www.trendhunter.com/trends/Solid-state-alloying) to produce dense components for [defense applications](https://www.trendhunter.com/trends/Defense-additive-manufacturing). For manufacturers and defense contractors, the expanded domestic capacity could strengthen access to critical materials and support more resilient supply chains as U.S. additive manufacturing adoption grows.
