Preparation an alloy with a composite structure was prepared using metallic technology (60 percent nickel, 25 percent silver, 15 percent iron and other materials). The dried ingot was stored under 6 tons of cold pressure at room temperature for 30 minutes, and the curing process was carried out at different heat treatment energies (0, 20, 60, 100) mJ for the purpose of studying the effect of heat treatment on the values of density, porosity, water absorption and magnetism and stiffness (Vickers method). The effect of heat treatment on corrosion resistance was examined by immersing the samples for different periods in a solution (3.5% NaCl). It is (2,4,6,8,12) days. The results showed that the porosity and water absorption rate decreased after treatment with an increase in the hardness value. In addition, the wear resistance decreases with an increase in heat treatment energy and a decrease in magnetism with an increase in heat.
