A heat sink is a device or fixture that transfers heat from a component, such as the CPU or processor, it acts like a radiator in which it transfers the heat into the air. Aluminum is shaped by the extrusion process which is like squeezing tooth paste out of a tube.

Cast aluminum strength versus extruded aluminum?
Cast aluminum has one third of the strength of extruded aluminum. As a result, cast aluminum has the potential to experience deformities due to its elasticity.
How to tell the difference between extruded aluminum and stainless?
stainless is steel. aluminum is aluminum
What is the difference between aluminum extruded bar and aluminum bar?
The extruded bar would be produced by pushing molten aluminum through a die. Where as the other option for making the bar would be to cast it in a mould. The extruded bar would probably have smoother sides and would be available in longer lengths.
What is the purpose of the copper or aluminum between a processor and the fan on a computer motherboard?
The heat sink absorbs the heat from the processor and then the fan disperses the heat.
Why is a computer heat sink made of copper?
Heat sink/s are made of copper and also aluminum because of its ability to quickly absorb and cool down heat. Copper is better then aluminum when it comes to heat transfer, however copper is heavier then aluminum as well as being more expensive.
What is the function of the heat sink?
A heat sink is a device that allows the transfer of heat away from the heat source. It can be in the form of a paste or jelly or a simplealuminum structure which is attached to the heat source. Virtually all microprocessors in computers utilize a heat sink to transfer the heat of the CPU to the aluminum which can 'shed' that heat into the air (air transfer method). Some CPUs are water cooled; one might say that this is a 'water heat sink' but that really isn't true.
What is extruded aluminum used for?
Extruded aluminum is used for a wide range of purposes from simple components like doors and components of computers, tents, trailers, power tools and kitchen appliances to components of the International Space Station.
Will a lump of aluminum sink or float?
Sink
What is the difference between extruded aluminum and powder coated aluminum and anodized aluminum?
Extruded aluminum is aluminum that is melted down and extruded, pushed through a certain 2d shaped hole. This can result in square tube, rectangular tube, an L shaped extrude, and an infinite array of other shapes. Powder coated aluminum is aluminum that could be extruded aluminum, that is cleaned, coated with a colored plastic powder, and then baked so that the plastic powder melts and forms a smooth, nice and even coat of colored plastic over the part. This is basically painting the part. Anodized aluminum is aluminum, again this could be extruded aluminum, but it couldn't be powder coated aluminum, that is put in a chemical solution, possibly sulfuric acid, and then a current is run through the aluminum. This causes a reaction to occur where a layer of aluminum oxide gathers on the surface of the part. The processes is then stop and the part can be colored if desired. Anodozing aluminum gives the part better corrosive resistance and makes the surface tougher and harder than it would have been if it had not been anodized. It does add thickness to the part which can be a downside, but it also is lighter than a powder coat if a paint job is desired.
Does a copper heat sink or an aluminum one with a base made of copper work any better than a pure aluminum one?
The thermal conductivity of copper is higher than that of aluminum, and silver is better than either copper or aluminum.
How do you know if your computer's heat sink needs to be replaced?
If you change the processor to one that generates more heat than the sink can dissipate you will need to put a larger sink in your computer, but if the processor is the same and you haven't overclocked or anything, the sink will last forever. It's made from cast aluminum and just sits there. It won't wear out.
Where might I find products made with aluminum die casting?
A few porducts of aluminium die casting are heat sink, and metal stamping. Distributors of foreign-made aluminum die castings are less expensive. You can find aluminum dye casting on the kitchen faucets of your sink. You can also find it on connector housings.
