Abstract
A study is performed of the effect additives containing chromium, zirconium, silicocalcium, and carbon nanotubes have on the physical and mechanical properties of copper obtained by casting. The tensile strength increased to 10.5%, and Young’s modulus increased by 11.6–106.2%. The resistance to heat of samples modified with SiCa and Cu-Zr is enhanced by 1.9 and 1.5 times, respectively, while modifying samples with nanotubes reduces their resistance to heat by 1.2–1.8 times.
