The extruded aluminum heatsink is a widely used material whether, for designing LED lights, computers, or other electronic parts, it comes in handy in a lot of ways. The main job of the heat sink is to absorb and dissipate the heat from the devices and helps them to stay cool.<\/p>\n

There are many materials used to manufacture heat sinks, but extruded aluminum heatsink is the most widely option. The aluminum heat sink offers benefits like low weight, low density, high strength, and various other benefits.<\/p>\n

So, let\u2019s find out why the extruded aluminum heatsink is the most preferred material for the heat sinks.<\/p>\n<\/div>

Why extruded aluminum heatsink is most preferred?<\/h2>\n<\/div>

The extruded aluminum heatsink is the widely used material for the heat sink because of its thermal conductive properties, natural electrical conductivity, and less weight of aluminum. Also, aluminum is the second most widely used metal in the world after iron.<\/p>\n

The heat sink made by the extruded aluminum comes with greater strength, and also when compared to the other metal, it shows higher thermal conductivity. Here are the properties lists that make aluminum the best metal for the heat sink:<\/p>\n

    \n
  1. Good thermal and electrical conductivity<\/li>\n
  2. Comes with a low density<\/li>\n
  3. One of the most important properties is aluminum is lightweight material<\/li>\n
  4. Offers high strength between 70 and 700MPa<\/li>\n
  5. Easy machining<\/li>\n
  6. Easy malleability<\/li>\n
  7. Offers high corrosion resistance<\/li>\n
  8. It is non-magnetic so it will avoid the interference of other magnetic fields<\/li>\n
  9. Eco-friendly as aluminum can be easily recycled<\/li>\n<\/ol>\n<\/div>

    Thermal conductivity is the most important performance in the choice of heat sink<\/a> material, and different materials have different thermal conductivity.<\/p>\n<\/div><\/div><\/div>

    Object<\/th>\nThermal conductivity = k = W \/(m k)<\/th>\n<\/tr>\n<\/thead>\n
    Diamond<\/td>\n1300-2400<\/td>\n<\/tr>\n
    Silver<\/td>\n429<\/td>\n<\/tr>\n

    Aluminum<\/td>\n240<\/td>\n<\/tr>\n
    Iron<\/td>\n84-90<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div><\/div>

    Obviously, the diamond has excellent thermal conductivity.\u00a0Diamond not only has ultra-high thermal conductivity but also it\u2019s excellent mechanical, optical, acoustic, electrical, and chemical properties, which makes it significantly superior to other materials in terms of heat dissipation of high-power optoelectronic devices. Of course, the cost of the diamond is extremely expensive, which makes it not the preferred material for ordinary heatsink products.<\/p>\n

    The metal with the best heat dissipation is silver, but it is very soft, which is not conducive to manufacturing high-density devices such as heat sinks. As a precious metal, gold is not a suitable heatsink material because of its expensive cost. The lowest cost material is iron, but its thermal conductivity is only one-third of that of aluminum, which is not a good heatsink material. But it is mostly used for radiators for homes because of good corrosion resistance.<\/p>\n

    These factors have led to the current use of copper or aluminum as popular heatsink materials.<\/b><\/strong><\/p>\n

    Copper has better thermal conductivity than aluminum. However, when considering thermal conductivity, the cost is another factor that cannot be ignored. The thermal conductivity of copper is twice that of aluminum, but its density is three times that of aluminum. This means that the weight of a heat sink that provides similar heat flow in copper will increase by about 50%. Actually, many copper heat sinks are overweight beyond design limits on weight. When calculating the cost per ton (copper is currently about 3.5 times the cost of aluminum), and you will find that the cost of copper will be much higher than that of aluminum solutions for the same heat sink design.<\/p>\n

    Aluminum, especially 6xxx-series aluminum alloy, can be simply extruded into various shapes, including complex heat sinks. Although copper can also be extruded, such as rods, it is very difficult to extrude into the shape of a heat sink, and the cost is also very expensive.<\/p>\n

    These factors make extruded aluminum heatsink most preferred.<\/b><\/strong><\/p>\n

    Depending on the design and shape of the heat sink, the aluminum can be designed. Other than the mechanical properties, the metal is easy to manufacture and customize.<\/p>\n<\/div>

    Is aluminum the right material for the heat sink?<\/h2>\n<\/div><\/div><\/div>

    The extruded aluminum heatsink is the most important material for the electronic components to prevent overheating. As, it offers high conductivity so it will carry the heat away and if you don\u2019t use an effective heat sink then your electronic components will get burnt.<\/p>\n

    The extruded aluminum heat sink is widely known for its excellent heat dissipation, so it is mostly used for heat sinks. You can find extruded aluminum heatsink in the automobile industry, winder power generation, construction machinery, railway locomotive industry, computers, household appliances, and others.<\/p>\n

    Without any doubt, the extruded aluminum heatsink can be used, as it is the trustable material of every industry. Even the extruded aluminum heat sink is available in different sizes, so depending on the needs the size can be customized.<\/p>\n

    So, here are a few reasons if you think why the extruded aluminum heatsink is used more when compared to the other materials:<\/p>\n
