Ceramic materials, for example, have the advantages of high hardness, wear resistance, high-temperature resistance, and corrosion resistance, making them ideal materials for high-precision parts in harsh environments such as aerospace and high-temperature equipment. Precision ceramic bearings used in aircraft engines can withstand high temperatures above 1000℃ and maintain stable rotation accuracy, greatly improving the reliability and service life of the engine. Composite materials, such as carbon fiber-reinforced composites, have the characteristics of light weight, high strength, and good toughness, which are widely used in the production of precision parts for new energy vehicles and aerospace equipment, helping to reduce the weight of equipment and improve energy efficiency. High-purity alloys, with their uniform composition and stable performance, ensure the ultra-high precision of parts, making them suitable for precision instruments and electronic products that require strict dimensional control.
