A kind of 3003 aluminum alloy for aluminum alloy heat sink

Abstract

The invention provides a 3003 aluminum alloy for aluminum alloy cooling fin. The 3003 aluminum alloy can effectively improve yield strength of the cooling fin after brazing, enhance overall strength of a radiator core body, and prolong service life. The 3003 aluminum alloy is characterized by containing the following materials in a total weight part of 100:0.7-1 part of silicon (Si), no more than 0.3 part of iron (Fe), no more than 0.05 part of copper (Cu), 0.8-1.2 parts of manganese (Mn), no more than 0.3-0.6 part of magnesium (Mg), 1.2-1.8 parts of zinc (Zn), 0.1-0.2 part of zirconium (Zr) and the balance of aluminum (Al) and inevitable impurities.

[0002] An aluminum alloy heat sink made of 3003 standard aluminum alloy, which is brazed with the radiator water pipe to form a radiator core, wherein the 3003 standard aluminum alloy contains the following materials with a total mass fraction of 100 parts: silicon ( Si) ≤ 0.6 parts, iron (Fe) ≤ 0.7 parts, copper (Cu) 0.05-0.2 parts, manganese (Mn) 1-1.5 parts, magnesium (Mg) ≤ 0.05 parts, zinc (Zn) ≤ 0.1 parts , and the rest are aluminum and unavoidable impurity elements. During the use of the aluminum alloy heat sink, due to the low yield strength after brazing, the radiator core is easy to collapse during the brazing process. At the same time, the core body after brazing is resistant to The compressive strength is not high, and it is easy to deform during use
