3102 air-conditioner aluminum foil is a core material for air-conditioning heat exchangers, mainly used in finned heat exchangers to enhance heat transfer efficiency. Aluminum foil stock generally refers to thick sheets or coils produced through casting, rolling, or hot rolling processes, serving as semi-finished products that are further rolled into thin foils as thin as 0.08mm for final applications.

3102 belongs to the Al-Mn series wrought aluminum alloy, containing manganese (Mn) and small amounts of silicon (Si) and iron (Fe). It is similar to 3003 alloy but with slightly lower Mn content. 3102 aluminum foil is high-strength, corrosion-resistant, oxidation-resistant, and dimensionally stable.

MC Aluminum offers thickness ranges from 0.008mm to 0.2mm and widths from 250mm to 1650mm. Available temper options include O/H22/H24/H18, each providing different hardness and strength characteristics to meet various air-conditioner manufacturing requirements.
