The invention belongs to the technical field of novel materials, in particular to a high strength nanoscale silicon carbide copper-based alloy novel material for marine engineering. The high strengthnanoscale silicon carbide copper-based alloy novel material for marine engineering comprises the following components in parts by weight: 1-2 parts of nanoscale silicon carbide and 90-95 parts of a copper-based alloy, wherein the copper-based alloy comprises the following components: copper, rare earth elements, aluminum, zinc, nickel, manganese, tin, cobalt, zirconium and chromium. According to the high strength nanoscale silicon carbide copper-based alloy novel material for marine engineering provided by the invention, by adding a nano microcrystal material which is high in hardness, high insmelting point, high in heat conductivity and oxidization-resistant into the copper-based alloy, not only are the impact strength and arc-burning resistance of the copper-based copper improved, but also the corrosion resistance and the oxidization resistance of the copper-based alloy are improved. The novel material meets the using demands.
