Cryogenic Engine development is our success in space technology. It is used in low and high temperatures because fuels such as liquid oxygen or liquid hydrogen are involved. It is made up of special alloys and great care is taken for the materials used. Cryogenic engine help to launch 2.5 tone satellites and put them into geostationary transfer orbit at 36,000 km from Earth’s Surface. This paper aims to discuss the material super alloy and its properties. This paper gives a brief overview about the one of the material used and its properties, characteristics and further uses in aerospace. Now we realize the need for research on this subject that determines the quality, safety, and durability of aerospace materials. This paper brings out the above need and describes super alloys and its requirement in these fields.
