Skiving machine producing copper heat sink fins. Skiving is also used for the manufacturing of heat sinks for PC cooling products. A PC cooler created by skiving has the benefit that the heat sink base and fins are created from a single piece of material (copper or aluminum), providing improved heat dissipation and heat transfer from base to fins.
Mill finish is the surface texture (or finish) of metal after it exits a rolling mill, extrusion die, or drawing processes, including sheet, bar, plate, or structural shapes. ...
Usually plain carbon steel is extruded, but alloy steel and stainless steel can also be extruded. Titanium (1100 to 1825 °F (600 to 1000 °C)) aircraft components including seat tracks, engine rings, and other structural parts. Magnesium and aluminium alloys usually have a 0.75 μm (30 μin) RMS or better surface finish. Titanium and steel can ...
Commercial extruded aluminium heat sinks have a thermal resistance (heat sink to ambient air) ranging from 0.4 °C/W for a large sink meant for TO-3 devices, up to as high as 85 °C/W for a clip-on heat sink for a TO-92 small plastic case. [3]
It can also be moulded, extruded, skived, stamped, and hot and cold formed. Below is a table of properties pertaining to Rulon AR, but note that the other types of Rulon have similar properties.

Fins are extensions on exterior surfaces of objects that increase the rate of heat transfer to or from the object by increasing convection.This is achieved by increasing the surface area of the body, which in turn increases the heat transfer rate by a sufficient degree.
Material of the profile to be extruded plays an essential role in determining process parameters and potential limitations of a process. For example, minimum thickness of extruded carbon steel sheet is 3mm whereas same sheet of aluminium can be extruded into minimum sheet thicknesses of 1mm.
T-slot structural framing is a framing system consisting of lengths of square or rectangular extruded aluminium, typically 6105-T5 aluminium alloy, with a T-slot down the centerline of one or more sides.
