AEROSPACE

Superalloys are critical materials for high-temperature, high-pressure industrial environments. Composed mainly of nickel (Ni), cobalt (Co), and iron (Fe), they also contain strategic metals such as chromium (Cr), molybdenum (Mo), aluminum (Al), titanium (Ti), tungsten (W), and tantalum (Ta). These elements stabilize microstructures and enhance performance under thermal stress.


Superalloy Applications in Extreme Environments

Thanks to their excellent strength, corrosion resistance, and oxidation resistance, superalloys are used in aviation engines, gas turbines, nuclear reactors, and petrochemical plants. These sectors demand materials that perform reliably under extreme conditions.

However, producing superalloys is costly. Raw material prices remain high, and the process is complex. Many of the core metals—especially nickel, cobalt, molybdenum, and tantalum—have limited global reserves and are mined in politically unstable regions. This puts pressure on the supply chain and increases reliance on imports.


Why Superalloy Recycling Matters

Superalloys hold immense resource value. Their rare metal content makes them ideal candidates for recycling. Dong-A Special Metals, Inc. recognizes this opportunity and leads the way with advanced recycling technology. Our processes recover high-purity metals from scrap and return them to the supply chain without further alloying. This saves energy, reduces emissions, and lowers costs.

The aviation and power generation sectors frequently replace high-performance components. This results in a steady flow of high-grade superalloy scrap. Recycling this scrap is faster and more cost-effective than refining virgin ore. In fact, studies show that recycling nickel and cobalt can reduce carbon emissions by up to 80%.

Environmental impact is another major factor. Mining new ores requires massive energy, water, and chemical use. Recycling reduces waste and conserves natural resources. Dong-A Special Metals supports this sustainable approach and supplies eco-friendly remelt materials to domestic manufacturers.


The Circular Future of Superalloy Use

Recycling is not just about cost—it’s a strategic necessity. It stabilizes supply, reduces reliance on volatile markets, and aligns with national goals for carbon neutrality. As demand grows for hydrogen turbines, EV components, and next-gen power systems, secure access to high-quality superalloys becomes crucial.

Dong-A Special Metals actively partners with domestic industries to provide a stable, high-quality source of recycled superalloys. Our work supports carbon reduction, resource circulation, and domestic manufacturing.
