Thick Household Aluminum Foil Roll Coil
Thick foil ("heavy gaugefoil"): foil with a thickness of 0.1 to 0.2 mm.One of the uses of aluminum foil:Air-conditioning foil is used in the manufacture of air-conditioning and is an important part of air-conditioning - a special manufacturing material for heat exchangers. Air-conditioning foil is an aluminum foil with less metallurgical defects and good ductility, so it has good formability during processing, and the aluminum foil material is very uniform. After post-corrosion and other processing, the air-conditioning foil also has good surface properties. Generally speaking, the thickness of the air-conditioning foil is between 0.10-0.15 mm, but due to the gradual exquisite processing technology, the thickness of the air-conditioning foil tends to decrease. For example, the thickness of the air-conditioning foil produced in Japan can reach only 0.09 mm.
The mechanical properties of aluminum foil mainly include tensile strength, elongation, crack strength, etc. The mechanical properties of aluminum foils are mainly determined by the thickness. The national standard GB/T3189-2003 "Aluminum and Aluminum Alloy Foils" stipulates the longitudinal mechanical properties of aluminum foils in my country.In general, aluminum foil is light in weight, good in ductility, thin in thickness, unit. Small area quality. But the strength is low, easy to tear, easy to break when folded cracks and holes, so it is generally not used for packaging products alone. In many cases, it is compounded with other plastic films and papers to overcome its shortcomings.
