Aluminum fins have good electrical conductivity and heat dissipation properties, second only to copper among non-ferrous metals. Therefore, aluminum strips are currently used instead of copper strips as a commonly used material for fin radiators internationally.
Heat exchanger aluminum fins are a lightweight, formable and corrosion-resistant material used in everything from automotive radiators to heat shields. It can also be used in a variety of heating, ventilation and air conditioning (HVAC) equipment such as aluminum radiators, aluminum evaporators and aluminum condensers.
Aluminum fin blanks are primarily made from 1000, 3000 and 8000 series aluminum alloys. It is made by repeatedly rolling aluminum foil in a rolling mill into thin, flat sheets or coils. Aluminum fin stock is available in coil form or in specific alloys, temper conditions and thickness ranges. MC Aluminum looks forward to working with you to meet your fin inventory needs.
