Aluminum strips for fin radiator alloy

Aluminum strips for fin radiator usually use 6061 and 6101 aluminum alloy for the hardness and better processing ability. The aluminium strip for radiator is generally made of aluminum alloy 6000 series, due to the insufficient hardness of pure aluminum, it is not inconvenient to carry out a series of processing and technical improvement, although there are some manufacturers have already developed it, but it is also very expensive. Because of the processability and surface treatment of 6061 aluminium strips alloy are quite easy and simple, and the cost is quite low.

Some friends may ask, copper is the best one in today's radiator materials, and why not use it for fin radiator? Although the heat transfer coefficient of copper is almost twice that of aluminum, this does not mean that the heat dissipation effect of the copper heat sink can be twice that of the aluminium strip for fin radiator (the heat dissipation performance of the radiator is not only affected by the thermal conductivity of the material). Disadvantages of copper are higher price, higher quality, higher density, higher static gravity or a certain quality by controlling the volume of the radiator, unsatisfactory hardness, etc. Excellent plasticity of aluminium strips makes it possible to extrude the process of manufacturing radiators. Aluminum can be used to manufacture almost any shape of radiator, mature technology, cheap, high processing performance. Therefore, some of the radiators are manufactured using a combination of aluminum strips for fin radiator.
