1100 Aluminum Sheet VS 3003 Aluminum
Brazing is a joining method in which the molten filler material (solder) whose melting point is lower than the workpiece to be welded is heated to it and has sufficient fluidity to fully fill the gap between the two workpieces by capillary action. After solidification, the two workpieces are joined.
Those with a temperature higher than 427 °C are called brazing, and vice versa. The solder of aluminum-based brazing process has the advantage of low density. The raw material of heat exchanger is 1100 aluminum tube and 3003 aluminum. They like to use this brazing for making heat exchanger.
According to the reverse T-shaped fluidity test, it was impossible to join at 590 °C. Because the temperature was too low, the fluidity was not good, and the melting amount was not enough for the material to be joined. The critical condition for successful brazing is 610°C heating for 45 minutes.
In addition, according to the tensile test results of 3003 aluminum sheet, it is found that the heat treatment temperature is 610°C for 45 minutes or 60 minutes, the properties of the fins are stable, and the strength is only slightly lower than before heating. It is not that the heat treatment causes the strength of the fins to decrease, but the weld bead has higher strength.
1100 aluminum sheet is an ordinary non-heat treatment strengthening with 99.0% aluminum content. It has low strength but good ductility, formability, weldability and corrosion resistance. After anodizing, the corrosion resistance can be further improved while obtaining a beautiful surface.
