As India races towards becoming a global aerospace powerhouse, CUMI is proud to be at the forefront of driving innovation in advanced materials for the aerospace industry. With the country’s ambitious goal to develop its indigenous fifth-generation fighter jet engine and establish itself as a global MRO (Maintenance, Repair, and Overhaul) hub, one thing is clear: India’s aerospace sector needs indigenous solutions that deliver both performance and reliability—at scale.
If you are a part of the aerospace industry, whether in manufacturing, maintenance, or operations, CUMI offers materials science solutions that address key challenges—reducing costs, enhancing efficiency, while ensuring long-lasting performance. And it all starts with advanced ceramic coatings for critical engine components.

Why Thermal Spray Powders Are Critical For Aerospace
For any aircraft, the engine is the most crucial component—and it faces the harshest conditions. Operating at temperatures over 1500°C, with constant mechanical stress and wear, engine components need special protection. This is where thermal spray powders (TSPs) come into play.
But here’s the problem: Yttria stabilized Zirconia, the key material for engine-protective coatings, is currently 100% import-dependent in India. This not only puts pressure on cost and supply chain reliability but can also delay your ability to access cutting-edge solutions when needed.
How CUMI’s Advanced Ceramic Coatings Solve Your Challenges

At CUMI, we understand your challenges.
That’s why we’ve spent over 7 decades perfecting our high-purity ceramic powders, designed to withstand the extreme environments of aerospace engines.
