AEROSPACE

In today's rapidly advancing defense and aerospace industries, materials that withstand high temperatures, pressures, and mechanical loads are essential. Ordinary metals no longer meet the stringent performance standards required in these fields. That is why high-performance nickel-based superalloys, especially those in the Inconel series, have become critical components in modern military and aviation systems.


Inconel 625 and 718: Advanced Materials for Extreme Conditions


Inconel 625 is a nickel-chromium-molybdenum-niobium alloy known for its outstanding resistance to oxidation and corrosion. It performs exceptionally well in harsh environments such as marine structures, aircraft exhaust systems, and rocket nozzles. Thanks to its excellent weldability and strength retention without heat treatment, Inconel 625 is widely used in both defense and industrial sectors.

Inconel 718, another nickel-based superalloy, features precipitation-hardening properties. Made from a blend of nickel, chromium, iron, niobium, molybdenum, titanium, and aluminum, it maintains superior mechanical strength and creep resistance at temperatures exceeding 650℃. This makes it ideal for use in turbine blades, jet engine discs, and missile structures where both thermal and mechanical stress are extreme.


Growing Strategic Importance of Superalloys in Korea


As advanced weapons systems like hypersonic missiles and sixth-generation fighter jets evolve, the role of superalloys becomes even more prominent. Korea, aiming for self-reliance in defense technology, is focusing on the localization of high-performance alloys like Inconel 625 and 718. However, current dependence on imports creates vulnerabilities in supply stability and cost management.

Dong-A Special Metals is leading the way by recycling titanium and nickel scrap to produce high-quality alloy materials. These recycled superalloys contribute to Korea’s material independence and resource circulation, supporting carbon neutrality goals while ensuring material availability for key industries.

Nickel-based superalloys must be treated as both technological assets and strategic resources. Sustainable competitiveness in defense and aerospace will depend on continued investment in recycling technologies and policy support for domestic alloy production.

If your company requires reliable, eco-conscious supply of nickel and titanium superalloys, contact Dong-A Special Metals. We proudly serve both Korean and global partners with sustainable, high-performance solutions.
