First of all, Aluminum heat sinks are produced by die casting by a Die Casting Company, a process wherein molten metal is forced is forced into mold cavities. The die casting process is beneficial if you are producing large quantities of small to medium sized automotive parts with good details. Prior to the introduction of die casting, most heat sinks are made by welding several pieces together and drilling holes, if required, after. This process is time consuming, costly, and labor extensive. Die cast aluminum heat sinks are good as raw parts but they can be powder coated and anodized easily.
Second of all, Die Cast Aluminum heat sinks can be manufactured in a much faster rate—ranging from a few hundreds to a few thousands small to medium sized parts a day—because they can be produced in net shape and there are no welding and drilling methods needed after. Die casting saves time, money, and energy all together.
Thirdly, Die cast aluminum heat sinks are definitely lighter than their stainless steel counterparts, with a specific gravity of about 0.10 pounds per cubic inch. Because they are electrically conductive, aluminum heat sinks are used for radio frequency (RF) and electronic magnetic inductance (EMI) shields. This quality also allows them to be grounded easily.
Aluminum heat sinks are used in airplane parts, circuit boards, microwaves, cellular phones, satellite components, laser components, motor housings, automotive, lighting parts and many more.
