Extruded metal heat sinks are among the lowest cost, widest used heat spreaders in electronics thermal management. As an Aluminium Profile Manufacturer, I will share with you some information of extruded aluminium heatsink.
Most extruded heat sinks are made from aluminum alloys, mainly from the 6000 alloy series, where aluminum dominates. Trace amounts of other elements are added, including magnesium and silicon. These alloys are easy to extrude and machine, are weldable, and can be hardened.

Aluminum alloys are popular for extruding as heat sinks because they provide both malleability and formability. They can be easily machined and are as little as one-third the density of steel. This results in extrusions that are both strong and stable, at a reduced cost relative to other materials.Compared with the others, aluminium heat sink has its own characteristics: the distance between the heat sink is short, between two adjacent heat sink to form a trough, and its large aspect ratio; differential wall thickness, heat sink teeth thin, and its roots in the bottom thick. The mold design, manufacturing, and production are very difficult for the complexity of the shape of radiator extruded sections.
The extruded heatsink provides effective cooling for LED (Light Emitting Diode) sources.
Hoonly aluminum heat sinks extrusion can provide a highly effective heat management process for circuit boards & PCB by providing a precise combination of vertical and horizontal cooling. Various thicknesses and customized forms are also easily achievable.
Hoonly manufactures heat sinks that are essential equipment for the electric appliance that can effectively dissipate output transistor heat.
The heat sinks for automotive electronic equipment that enables high-density components to operate at stable temperatures over a wide spectrum of ambient conditions.

An extruded heat sink is used mainly to increase the surface area available for heat transfer from high-power semiconductor devices, thus reducing a given semiconductor’s external case temperature, as well as its internal junction temperature.This allows the semiconductor devices to perform at their highest level, with maximum reliability. Such semiconductor devices include (but are not limited to) RF power transistors, RF power amplifiers and so on.In some power conversion circuit applications, large diodes, rectifiers, diode modules and even high-power resistors (thick film, etc.) can also require thermal contact with an extruded heat sink.
The purpose of heat sinks are specially designed to extract heat from components in the electronic devices. Usually, the heat sinks are mill finish, and more, they can be anodized or powder coated to improve the surface protection and corrosion resistance.Besides their affordability, extruded heat sinks are lightweight, readily cut to size and shape, and capable of high levels of cooling.
