Nuclear power has the characteristics of less pollution and close to zero emissions of greenhouse gases. It is a typical high-efficiency clean new energy source and is the preferred choice for optimizing energy structure in China. The safety performance of nuclear power equipment is extremely high, and the quality requirements are very strict. The key materials of nuclear power are roughly classified into carbon aluminum, low alloy aluminum, stainless aluminum, nickel-based alloy, titanium and its alloy, and zirconium alloy. As the country began to vigorously develop nuclear power, the company further increased its supply capacity and is making important contributions to the localization of China's nuclear power key materials and equipment manufacturing.
