Into the 20th century, the rapid development of casting, one of its important factors is the progress of product technology, requiring castings of various mechanical and physical properties better, while still having good machinability; another reason is the development of the machinery industry itself and other industries such as chemicals, instruments, etc., to create favorable material conditions for the casting industry. Such as the development of detection means to ensure the improvement and stability of the quality of castings, and to the development of casting theory provides the conditions; electron microscope and other inventions to help people delve into the microscopic world of metals, to explore the mysteries of metal crystallization, the study of the theory of metal solidification, to guide the casting production.

 

Within this period developed a large number of superior performance, rich variety of new casting metal materials, such as ductile iron, weldable cast iron, ultra-low carbon stainless steel, aluminum-copper, aluminum-silicon, aluminum-magnesium alloy, titanium-based, nickel-based alloys, etc., and the invention of a new process of inoculation treatment of gray cast iron, so that the adaptability of castings more widely.
