Development of Naval Alloy by Casting Process

Abstract This research paper focuses on the development of naval alloy by using typical casting process. Copper, nickel and chromium are the alloying elements in this new alloy. Copper is acting as a base metal whereas nickel and chromium are the main alloying elements. Chromium is used in a very small amount as it is so much costlier. All the properties of these metals are analyzed and then only they are chosen for the preparation of the alloy. After selecting the material the design and dimensions of the desired casting of the alloy are finalized and according to this design, the casting of the naval alloy is done. Typical sand casting technique is used for the preparation of the naval alloy which involves melting of the metal in the furnace and pouring the molten metal in the mould of desired shape of the casting. The specimen of the naval alloy obtained from the casting directly will not have good surface finish and so machining is done on this casted specimen to improve its surface finish. This machined specimen is the desired Naval alloy. Keywords: Naval, alloy, chromium, casting, copper base.
