Does the power conductive "copper-aluminum composite plate" deform when heated?
2024-04-30
Copper aluminum composite plate is made of copper and aluminum two kinds of metal through a certain process of composite materials. Both copper and aluminum are metals, and metals usually undergo thermal expansion when heated, which is an inherent property of metal materials. Thermal expansion refers to a phenomenon in which the average distance between atoms increases when the temperature of an object increases, resulting in an increase in the volume of the object.
Specific to copper-aluminum composite panels, due to the different thermal expansion coefficients of copper and aluminum, their degree of expansion when heated will also be different. This different degree of expansion may lead to internal stresses in the composite plate, which may lead to deformation of the composite plate if these stresses exceed the bearing limit of the material.
Ningbo, Zhejiang: East-West Industrial Collaboration Hatches "Golden Phoenix"
Just after the Spring Festival, in the heavy Industrial Park in Xingren Baling Town, Guizhou, as one of the industrial cooperation projects in the Yangtze River Delta region and the western region, a new production line built by a group in Ningbo has attracted much attention. "This production line will produce a new product called'copper-aluminum eutectic plat', which will be independently developed by our team for more than two years." Xu Yinchang, the person in charge of the enterprise, introduced.
