The  aluminum is the preferred material to make the extruded heat sink, because aluminum is an excellent conductor of heat with light weight and low price, and it is the most widely used material for the thermal industry. As the pure aluminum is too soft, so usually the we will use the aluminum alloy to manufacture the heat sinks with specific requirements or higher hardness requirements. electronic products have been developing rapidly in recent years. Taking mobile phones as an example, it has become a trend to replace them every two years or even once a year. The design of electronic products is becoming more and more refined, and there are also new requirements for heat dissipation. It is more energy efficient and lighter at the same time.

The market demand is the research direction of aluminum heat sink manufacturers. How to innovate in the process, material and design of the heat sinks is the consideration that the experts of heat sink manufacturing should think about. Sinda Thermal has increased their investment in research and development of aluminum heat sinks, and increased their cooperation with scientific research institutions and universities to research the innovations of new aluminum heat sink technologies.

Aluminum heat sinks are also widely used in the field of LEDs. LED heat sink have also made great innovations in recent years. The combination of new materials such as thermomagnets, graphene, and aluminum extrusions and aluminum materials, and then through the internal structure or external The optimization of the shape can provide the heat dissipation efficiency of the LED very well. In the field of new energy, the combination of aluminum heat sink, heat pipe and water-cooling pipe, the heat pipe heat sink and liquid cooling plate heat sinkr are often used for high-power thermal solution, and can also be applied on new energy vehicles, photovoltaic inverters, etc. 

Why does the aluminum heat sink extrusion need anodizing?

As we all know that aluminum is a material with good thermal conductivity, so it is mostly used in the production of varieties of heat sinks. Aluminum heat sinks are not made of pure aluminum. the material of aluminum is soft and has poor corrosion resistance, so usually the aluminum alloy such as AL 6063 alloy is the most common material and  some necessary surface finish will be treated on the aluminum heat sink. Anodizing is a common surface treatment method.

Anodizing usually refers to sulfuric acid anodizing, which is the process of forming an oxide layer on the aluminum product (anode) under the action of an applied current under the corresponding electrolyte and specific process conditions. The performance of the alloy surface hardness and wear resistance has been improved, thereby expanding the application range and prolonging the service life of the aluminum heat sink.

In addition, the color of the aluminum heat sink can be customized  after anodizing, but the most common color is black, so anodizing is also called black anodizing, or black oxidation. The anodization of the aluminum heat sink can also increase the aesthetics of the product. Many electronic product substrate boxes are black. If the heat sink is black, it can form a uniform color tone and increase the aesthetics. Some customers' water-cooled plate heat sinks will also undergo anodizing surface treatment, especially for liquid cooling  plates on optical instruments such as lasers.
