One of the most common types of metal surface treatments such as steel and aluminum composite panel used is heat treatment. It is designed to increase the strength and hardness of the metal in question. As for the heat treatment of aluminum and its alloys, three basic steps are all that is needed. The result is a piece of metal as it was much harder and stronger at the beginning, making it much more suitable for its application. Read on to learn more about the different stages of the process:



The first step of heat treatment of aluminum composite panel is to soften the metal. This softening can be totally or partially, and requires that the aluminum is heated somewhere 300-410 degrees Celsius. This step can last between half an hour and three hours, depending on whether it is an alloy or pure metal and the size of the piece is.


Annealed solution

The second stage of the heat treatment of aluminum composite panel is known that the heat treatment in solution, in which the soluble parts of the metal or alloy of dissolution are dissolved. The time required for this step depends on the substance and the furnace charge, as the time for melting the alloy to the solution form is different.



This is the third step in the heat treatment of aluminum composite panel, but since it actually occurs during the solution heat treatment step, it is often included as a second step. Tempering (or super saturation) is The method that is used to ensure that each of the melt substances in step 2 retains its shape.
