This is the heat dissipation data commonly used in modern heat dissipation. Most of the industry uses 6063t5 high-quality aluminum material. Its purity can reach more than 98%. Its heat conduction ability is strong, its density is small, and its price is cheap, so it has won the love of major manufacturers.

According to the thermal resistance of Intel and AMD CPU and the consideration of its fever, the aluminum extrusion manufacturer formulates the corresponding mold, heats the aluminum ingot to a certain temperature, so that its physical shape can be changed, and then comes out of the mold to obtain all kinds of heat sink raw materials we want; then it can be applied by cutting, trenching, grinding, deburring, cleaning and surface treatment.

As for the material of aluminum extruded heat sink, the heat conduction function of each material is different. According to the heat conduction function displayed from high to low, it can be distinguished as silver, copper, aluminum and steel. However, if silver is used as heat sink, it will be too expensive, so copper is recommended. Although aluminum is much cheaper, its apparent thermal conductivity is not as good as copper (about 50% of copper).

At present, copper and aluminum alloy are the common materials of extruded fins for aluminum shell, which have their own advantages and disadvantages. Copper has good thermal conductivity, but the price is expensive, the processing difficulty is high, the component is too large (many pure copper radiators have exceeded the CPU's limit on the component), the heat capacity is small, and it is easy to oxidize. But pure aluminum is too soft to be used directly. Only the aluminum alloy can supply enough hardness. The advantage of aluminum alloy is its low price.

Taishan zhiyahui Hardware Products Co., Ltd. was founded in 2016. Its predecessor is Foshan Jianxing aluminum products factory. It specializes in the production of all kinds of aluminum alloy shells and industrial aluminum materials. The company has a number of advanced equipment to undertake all kinds of aluminum deep processing.
