In this article, research on smelting technology of elastomeric copper alloy of Cu-Ni-Sn system grade C72500 in vacuum induction furnace and some results of studying the structure and mechanical properties of C72500 alloy were shown. The C72500 alloy was smelted in a vacuum medium frequency furnace with a small burning rate and high cleanliness. Some methods to evaluate by determining structure, mechanical properties as: EDX spectroscopy analyzes element content, Optical microscope equipment to determine microscopic structure, ultrasonic equipment to evaluate defects and equipment to test mechanical properties. The after-casting alloy has a chemical composition and mechanical properties equivalent to imported copper alloys according to ASTM B122/B122M-20 standards, single α phase structure, good ductility but low strength, elongation 62.2%, tensile limit 301.43 MPa, yield limit 171 MPa and hardness distributed along the sample, high on the outside (82.4 HV) and low in the center (73.4 HV), is used in manufacturing elastic, abrasion and corrosion resistant parts.
