What beneficial for cooling die-casting or extrusion and why?
A1: Extrusion is most beneficial than dye casting. Dye casting is used only in 25 – 30 % of Aluminum alloy and the rest carbons and other alloys. In dye cast always it happens for air gap area. In extrusion use 70 % – 80% 0f aluminum alloy and 20 % carbon and other alloys. Aluminum is extruded always in semi-solid form which is made of above mentioned specified material and it is stretched and pressurized by a heavy hydrolic pressing system and after all the same is provided for edging. Dye casting has 30% – 40% less transparency of heat than extrusion due to excessive quantity of carbon in the material. In the same way extruded aluminum heat sink has 30-40% more transparency due to purity of excessive existence of pure aluminum alloy.
