Aluminum alloys are often highly malleable, which makes the design of aluminum extruded profiles larger varieties. Because aluminum is a good conductor of heat and thermal reflectors, it is a great choice for heat exchange applications and thermal shields. Compared to other metals, aluminum alloys are made to make wider shapes at lower cost. In particular, aluminum can be molded into foil, fins, or slices, making it perfect for all kinds of thermal products.

The cooling mechanism usually requires high-strength material at light weight. Only aluminum, with its improved aluminum extrusion, provides the proper combination to affordable costs. Aluminum has been proven several times to have a higher weight ratio than steel, brass or copper. The conductivity of aluminum radiator is also an important consideration in many industries.

Another advantage of aluminum is its low melting temperature makes it easier to squeeze or cast, while also providing high levels of shape complexity, dimensional performance, and other high-capacity applications. In particular, the density of aluminum injection may be low, but its thermal conductivity is still very high.

Heat sink made of aluminum profile has a beautiful appearance, light weight, good heat dissipation performance, energy-saving effect, and so on.

The machined aluminum heat sink surface is treated by anodic oxidation to increase the corrosion resistance, abrasion resistance and appearance of aluminum alloy.

At present, commonly used heat sink aluminum profile types are: Electronics, electrical appliances, computers, power semiconductors and so on.

Aluminum heat sink, because of its superior performance has been widely used in: machinery, automobiles, wind power, engineering machinery, air compressors, railway locomotives, household appliances and other industries.
