What refers to the mechanical properties of aluminum foil?
The factors affecting the mechanical properties of the aluminum foil more processes are chemical composition and processing of the foil. On the strength and ductility for the aluminum foil by adjusting the chemical composition or change the machining process and parameters, or the strength of the plastic material in a certain range while maintaining a constant so that the other party has changed. That is, the value can be changed with the strength and ductility of aluminum foil limited by adjusting the chemical composition and processing technology.
Therefore, in practice, generally take the mechanical properties of intermediate values, and specific strength and ductility values ??but also with the heat transfer sheet punching mold machining related. Punching processing sheet heat exchanger is divided into general type and stretching unstretched two. Stretched punching processing plastic mold foil requirements better, that higher elongation, the relative intensity values ??may slightly lower; without drawing mold with higher strength aluminum foil, plastic belong secondary indicators.
Mechanical properties mainly refers to the tensile strength of aluminum foil, elongation and Erichsen value. From the use of perspective, I hope these three indicators, the higher the better, but on the material itself, these three indicators and mutually contradictory, that is, when the tensile strength of the aluminum foil is relatively high elongation index will decline; and when improving the elongation of the aluminum foil, it will cause a decline in tensile strength.
