6061 6063 aluminum extrusion heat sink

6061 6063 aluminum extrusion heat sink.Technical:Extrusion aluminum,could custom to CNC work.Custom according to heat sink samples or drawings.Aluminum extrusion (Extruded) technology: as containing the highest amount of metal in the crust, the low cost is its main features, and because of the aluminum extrusion technology and equipment costs are relatively low. So the aluminum have long been used in the heat sink market. Simply put, aluminum extrusion technology is to heat aluminum ingots to about 520~540℃ at high temperature, under high pressure to let the aluminum liquid flow through the extrusion mold with grooves, to make the first heat sink. Then, after cutting and cutting the first heat sink, the heat sink we often see is made.AA6063, which has good thermal conductivity (about 160~180W/m.K) and processability, is the most commonly used aluminum extrusion material. However, due to the limitation of its own material, the ratio of fin thickness and length cannot exceed 1:18, so i…
