Product  background Overview:

  With the rapid development of electronic products has brought great conveniences to our lives, but at the same time, it will also make us confront new challenges.Electronic products will face severe thermal  problems during operation. For example, in summer, using the computer for a long time, the CPU will generate plenty of heat and make the computer in high temperature .In order to avoid the electric devices shutting down due to high temperature, various types of heat sinks are designed to cool down the electronic components.

   It is very important to choose a good heat sink for the electronic products. Aluminum heat sink extrusion is a leading selection in thermal options, with it's beautiful appearance, strong metal texture, light weight, excellent heat dissipation effect and affordable price,  Aluminum heat sink extrusion is very popular in many industries.

   In order to absorb as much heat generated by the electronic components as possible in a short time,the heatsink  must have a high thermal conductivity. Aluminum 6063 alloy is a preferred selection for heat sink material, but why to choose 6063 aluminum alloy for extruded heat sink?

The benefits of 6063 aluminum alloy:

     First of all, the thermal conductivity of the aluminum 6063  alloy can reach to 201W/mk;It's strong thermal conductivity and can help electronic products dissipate heat well. There are several types of materials for heat sink manufacturing, the thermal conductivity of each material is different, and the thermal conductivity is listed from high to low, which are silver, copper, aluminum, and steel. However, silver  will be too expensive to build a heat sink, so the best solution is to use copper or aluminum, both of the materials have their own benefits.

      The commonly used heat sink materials are copper and aluminum alloys, both of which have their own advantages and disadvantages. Copper has good thermal conductivity, but it is expensive, difficult to process, too heavy in weight, small in heat capacity, and easy to oxidize; Pure aluminum is too soft to be used directly. Only the aluminum alloy used can provide sufficient hardness. The advantages of aluminum alloy are low price and light weight, but the thermal conductivity is relatively worse than copper. Some heatsinks take their own advantages and embed a copper plate on the aluminum alloy heat sink base. It can not only lower the price, but also ensure the efficiency of heat dissipation.

   Secondly, the 6063 aluminum is low-density and it is easier for manufacturing.Due to the low density of aluminum alloy, and it can be extruded to varieties of shapes and specifications, the extrusion section can be customized into plenty of geometric figures, the further dimensions can be easily machined by CNC, it's easy to produce a aluminum extruded heatsink, and production efficiency is very high.

    Thirdly, 6063 aluminum alloy has strong plasticity. The 6063 aluminum alloy heat sink extrusion can be subjected to various surface treatments, like sandblasting, anodizing, coating, etc. And the surface can be in various colors, strong decoration, beautiful and durable, and can meet customer's requirements.

Aluminum heat sink extrusions features

      Aluminum extruded aluminum profile heat sink has better thermal performance and it's energy-saving characteristics are very obvious, also it is a most cost effective heat sink type, and it is wildly used in plenty of industries such as LED, electricity appliances, electronical devices, computer, Server, etc.

     The aluminum extruded aluminum profile radiator has good oxidation and corrosion resistance and does not need to add any additives. The principle is that once aluminum encounters oxygen in the air, an oxide film is formed. This film is tough and dense, preventing further damage to the body.
