1. Chemical composition:
2. Mechanical properties:
Mechanical properties mainly refer to the tensile strength, elongation and cupping value of aluminum foil. From the perspective of use, it is hoped that the higher the three indicators are, the better. As for the material itself, these three indicators are contradictory. That is, when the tensile strength of aluminum foil is relatively high, the elongation index will decrease; and when the elongation of aluminum foil is increased, the tensile strength will decrease. Therefore, in practical application, the intermediate value of mechanical properties is generally taken, and the specific strength and plasticity values are related to the punching die in the processing of heat exchanger plate. Generally, the punching process of heat exchanger sheet is divided into drawing type and non drawing type.
Drawing die requires better plasticity of aluminum foil, i.e. higher elongation and lower relative strength value; while non drawing die requires higher strength of aluminum foil, and plasticity belongs to secondary index. There are many factors affecting the mechanical properties of aluminum foil, mainly chemical composition and processing technology. As for the strength and plasticity of aluminum foil, the plasticity or strength of one side can be changed within a certain range by adjusting the chemical composition or changing the processing process and parameters. In other words, the combination value of strength and plasticity of aluminum foil can be changed by adjusting chemical composition and processing technology.
According to the different requirements of heat exchanger for mechanical properties, there are three kinds of aluminum foil: H22, H24, H26. Each state corresponds to a certain range of strength and plasticity.
