Why material Alu6063 popular used for extrusion products

Why material Alu6063 popular used for extrusion products?

First, the thermal conductivity of the 6063 Aluminum Heat Radiator is strong.

At present, the commonly used aluminum radiator materials are copper and aluminum alloy, both of which have their own advantages and disadvantages. Copper has good thermal conductivity, but it is expensive, difficult to process, has high density, small heat capacity, and also easy to oxidize. While the hardness of the aluminum alloy is suitable, also they are with low cost and light weight.
