When it comes to heat sinks, manufacturers have a range of options to choose from depending on the application's requirements. Two of the most popular types of heat sinks are skived and extruded. In this article, we'll explore the differences between these two types of heat sinks and consider their benefits and drawbacks.1. What are Skived Heat Sinks?Skived heat sinks, also known as folded-fin heat sinks or cold-forged heat sinks, are made by slicing a block of aluminum into thin, flat plates that are then bent, folded, and bonded together to form the desired shape and size.2. What are Extruded Heat Sinks?Extruded heat sinks, on the other hand, are made using an extrusion process whereby a heated aluminum billet is forced through a die to create the desired cross-sectional shape. The extruded piece is then cut to the desired length and machined as required.3. Manufacturing DifferencesOne of the primary differences between skived and extruded heat sinks is the manufacturing process. Skived heat sinks are made using a cutting and folding process, while extruded heat sinks are made using a shaping process. The cutting and folding process used in manufacturing skived heat sinks is more precise, which can result in higher performance. However, it's also more expensive and time-consuming than the extrusion process used for manufacturing extruded heat sinks.4. Performance DifferencesSkived heat sinks have a higher surface area to volume ratio than extruded heat sinks, which means they can dissipate heat faster and more efficiently. However, this doesn't necessarily mean that skived heat sinks are always better than extruded heat sinks. The performance of a heat sink depends on a range of factors, including the application's requirements, size, shape, and the materials used.5. Design DifferencesAnother difference between skived and extruded heat sinks is the design possibilities. Skived heat sinks can be made in more complex shapes than extruded heat sinks because of the cutting and folding process used in their manufacture. This means that they can be more effective in dissipating heat from complex components and surfaces. Extruded heat sinks are typically simpler in design, but they can be produced in larger quantities and are more customizable in terms of length and width.6. Cost DifferencesAs mentioned earlier, skived heat sinks are more expensive to manufacture than extruded heat sinks. This is because the manufacturing process for skived heat sinks is more precise and requires more labor-intensive work. Skived heat sinks also require more machining and finishing work than extruded heat sinks, which adds to the Total Cost of Ownership.7. Application DifferencesThe type of heat sink that is best suited for an application depends on the application's specific requirements, including the size, shape, and heat dissipation needs. Skived heat sinks are often used in applications where higher cooling performance is required, such as LED lighting and audio amplifiers. Extruded heat sinks, on the other hand, are often used in applications that require a large heat dissipation area, such as computer power supplies and industrial equipment.8. Material DifferencesBoth skived and extruded heat sinks are commonly made from aluminum due to its high thermal conductivity and lightweight, making it an excellent heat dissipater. Other materials may also be used depending on the application's requirements, such as copper and graphite. Copper has a higher thermal conductivity than aluminum and is often used in applications where the heat source is very concentrated. Graphite is a good thermal conductor but is also brittle and less durable than aluminum and copper.9. Maintenance and Durability DifferencesSkived heat sinks are more prone to damage and require more frequent maintenance than extruded heat sinks. This is because the cutting and folding process used in the manufacture of skived heat sinks can create stress points that can break or fracture over time. Extruded heat sinks, on the other hand, have a more uniform structure and are less prone to damage over time.10. Selection DifferencesWhen selecting between skived and extruded heat sinks, it's important to consider the application's specific requirements and the desired performance levels. Skived heat sinks offer high-performance cooling but are more expensive to manufacture and maintain. Extruded heat sinks are more affordable and customizable in terms of size and shape, making them ideal for applications that require large heat dissipation areas.skived heat sinks, extruded heat sinks, heat dissipation, heat sink design, manufacturing process, material differences, maintenance, application differences, copper heat sinks, graphite heat sinksSkived vs Extruded Heat Sinks: What's the Difference?Discover the differences between skived and extruded heat sinks, including manufacturing techniques, performance, design, material, cost, and application use.

Why are heat sinks made of aluminum and not copper??When it comes to heat transfer, heat sinks are an integral part of any electronic device. With the increasing demand for faster and more powerful devices, the need for efficient cooling mechanisms has become even more crucial. Heat sinks are one such mechanism that helps dissipate heat from the device. Heat sinks can be made of various materials, including aluminum and copper. However, aluminum is the preferred choice for most heat sinks. In this article, we will explore the reasons why heat sinks are made of aluminum and not copper.1. Thermal ConductivityThe primary reason why aluminum is used instead of copper for heat sinks is its thermal conductivity. Thermal conductivity is the ability of a material to transfer heat. Aluminum has a thermal conductivity of 205 watts per meter Kelvin (W/mK), while copper has a thermal conductivity of only 385 W/mK. Although copper has a higher thermal conductivity, aluminum has enough thermal conductivity to make it an ideal choice for heat sinks.2. CostThe cost of production is another factor that makes aluminum a better choice than copper for heat sinks. Copper is a more expensive material compared to aluminum. Also, copper is denser than aluminum, which makes it a heavier material. Therefore, the production cost of a copper heat sink is higher than that of an aluminum heat sink.3. Corrosion ResistanceAnother reason for the popularity of aluminum in heat sinks is its corrosion resistance. Aluminum naturally forms a thin layer of oxide on its surface that protects it from corrosion. Copper, on the other hand, is prone to corrosion and needs to be plated or treated to prevent corrosion. The corrosion-resistant nature of aluminum makes it a better choice for heat sinks.4. Ease of ManufacturingAluminum is an easy material to manufacture, compared to copper.

The ease of manufacturing makes aluminum more accessible, which translates to lower production costs.5. WeightHeat sinks need to be lightweight to avoid putting additional pressure on the device. Aluminum is a lightweight material, and it does not add much weight to the overall device. Copper, on the other hand, is dense and heavy, which makes it unsuitable for heat sinks in lightweight devices. The weight factor also contributes to the cost of production, as copper requires more energy and resources to transport compared to aluminum.6. CustomizabilityAnother advantage of aluminum heat sinks is their customizability. Aluminum heat sinks can be easily designed and customized to fit the specific needs of the device. Copper, on the other hand, is harder to customize, and it may not fit into all device designs. The customizability of aluminum allows manufacturers to create heat sinks that fit the design and functionality of each device correctly.7. AvailabilityAluminum is the most abundant metal in the earth's crust, making it a readily available material for manufacturers. Copper, on the other hand, is rarer, and it is more expensive to mine and extract. The abundance of aluminum makes it a popular choice for heat sinks.8. DurabilityAluminum is a durable material that can withstand high temperatures without melting or deforming. Copper, on the other hand, is prone to melting at high temperatures, which makes it unsuitable for heat sink applications. The durability of aluminum makes it a reliable choice for heat sinks that need to perform under high-temperature conditions.9. Environmental ConcernsAluminum is a more environmentally friendly material than copper. Aluminum is easier to recycle than copper, and it requires less energy to recycle. Using aluminum heat sinks in electronic devices reduces the environmental impact of the production and disposal of these devices.10. AestheticsAluminum has a more appealing appearance compared to copper. Aluminum can be anodized to create a variety of colors and finishes. The aesthetic appeal of aluminum makes it an ideal choice for devices that require a sleek and modern look.ConclusionAluminum is the preferred choice for heat sinks due to its thermal conductivity, cost, corrosion-resistant properties, ease of manufacturing, weight, customizability, availability, durability, environmental concerns, and aesthetics.
