| 简介 |
One embodiment of the present invention comprises : 0.1-2.0 wt% of misch metal; 0.3 wt% or less of silicon (Si); 0.7 wt% or less of iron (Fe); 0.5 wt% or less of copper (Cu); 0.3 wt% or less of zinc (Zn); 0.1-2.5 wt% of manganese (Mn); and the balance of aluminum and extra inevitable impurities. According to one embodiment of the present invention, an aluminum alloy has improved corrosion resistance and strength by addition of the misch metal and content relationship of elements such as the misch metal, the silicon (Si), the iron (Fe), the copper (Cu), the zinc (Zn), and the manganese (Mn). Therefore, the aluminum alloy can be used as a component of a heat exchanger, and more specifically, an extrusion molding material of a microchannel-tube or a header pipe.(AA) Commercial alloy 1100COPYRIGHT KIPO 2017 |
