At high temperatures, copper forgings undergo some characteristic changes, and understanding these changes is important to ensure product stability and reliability. The following is the characteristics of copper forgings under high temperature environment: Melting point: The melting point of copper is low, about 1083°C. In high-temperature environments, copper forgings may soften or melt when the temperature approaches or exceeds the melting point of copper. Therefore, when designing and selecting copper forgings, it is necessary to consider the operating temperature at high temperatures and the high temperature resistance of copper. Coefficient of thermal expansion: The coefficient of thermal expansion of copper is relatively large, and when heated, copper forgings will expand. In high temperature environment, due to the influence of thermal expansion, copper forgings may be deformed or stress concentrated, which will affect its stability and reliability. Therefore, in the design and installation process, it is necessary to reasonably consider the thermal expansion characteristics of copper forgings, and take corresponding measures to reduce deformation and stress concentration. Oxidation and corrosion: In high temperature environments, copper forgings may react with oxygen, moisture or other chemicals for oxidation and corrosion. This leads to the formation of oxides on the surface of copper forgings, affecting their appearance and performance, and can lead to shortened life. Therefore, in order to ensure the stability and reliability of the product, anti-oxidation and anti-corrosion measures need to be taken in the high temperature environment, such as protective coating, alloy modification. Strength and toughness: In a high temperature environment, the strength and toughness of copper will decrease, which is easy to cause deformation and fracture. Therefore, in the design and selection of copper forgings, it is necessary to consider the load and stress in the high temperature environment, select the appropriate material and processing technology to improve the strength and toughness of copper forgings, and ensure its stability and reliability in the high temperature environment. In short, for copper forgings in high temperature environments, it is necessary to pay attention to the melting point of copper, coefficient of thermal expansion, oxidation and corrosion problems, as well as changes in strength and toughness. Through reasonable design and selection of materials, processing technology and protective measures, copper forgings can be ensured to have good stability and reliability in high temperature environment.
