v slot extrusion

In my opinion, no.

But is there a new substance that dissipates heat more effectively than aluminum?

The thermal conductivity coefficient's size is a measure of aluminum extrusion cnc a material's capacity to conduct heat; the higher the thermal conductivity coefficient, the lower the value of thermal resistance will be, and vice versa for the thermal conductivity of the capacity to increase.

Silver has the highest thermal conductivity of all metallic materials (table), yet it is expensive;

The next is pure copper, but processing is difficult.

Many individuals are always looking into the extrusion profiles greatest thermal conductivity of the best new materials to satisfy the electronic equipment, high power, and compact volume of the product design trend due to the improvement of heat dissipation demands.

Metal thermal conductive materials and non-metallic thermal conductive materials make up the majority of the existing categorization of thermal conductive materials.

The finest thermal conductivity materials are metals, of which gold and v slot extrusion silver are among the best. However, because of their high price, they are not practical for widespread usage.

The thermal performance of pure copper is second, but has been regarded as having very good qualities. However, copper sheets have their own drawbacks, including high cost, weight, poor molding, and corrosion resistance.

Additionally, the major problem of copper itself is its susceptibility to oxidize. The thermal conductivity and heat dissipation of copper in its previously oxidized state will be significantly decreased. As a result, aluminum alloy, which has the greatest thermal conductivity of all aluminum alloys, is currently used to make the majority of heatsinks. This means that high-quality CPU air-cooled heatsinks are often built of aluminum alloy.

The market is currently seeing the emergence of a brand-new process: integrated radiators made of copper and aluminum.

The so-called combination of copper and aluminum is the ideal combination of copper and aluminum general specific process to a piece, so that the copper rapidly transfers heat to the aluminum, followed by a large area of the aluminum to the heat dissipation, which not only increases the thermal conductivity of the aluminum is not as good as copper, but also compensates for the copper heat dissipation is not as good as the aluminum, the combination of the organic to achieve

Additionally, many non-metallic thermal conductivity materials are now used to meet the stringent insulation requirements of electronic products. These materials' thermal conductivity is not only tens of thousands of times higher than that of comparable metal materials.

The ones that are currently most often used are:

Initial, graphene

A single layer of carbon atoms in a hexagonal pattern densely packed in the shape of a honeycomb two-dimensional planar structure, graphene is a single layer of carbon atoms made from graphite by a unique method of peeling off the surface material. In the thermal conductivity material sector, single-layer suspended graphene with a room temperature thermal conductivity of 3000–5300W.m-1.K-1 is regarded as having the best thermal conductivity of emerging materials. Cell phones, tablets, electrical equipment, and other high-end electronic consumer goods have all made extensive use of graphene in their design and production.


Graphite is a very high thermal conductivity substance made of elemental carbon. A high directional cleavage of graphite in the direction of thermal conductivity is capable of reaching 2000W.m-1.K-1, according to study estimates, and graphite in the direction of the crystal layer parallel to the thermal conductivity theory can reach 4180W.m-1.K-1. Today, the two main categories of graphite thermal conductivity materials from the substrate are artificial graphite and natural graphite.

Third, materials made of carbon fiber and carbon/carbon

By carbonizing and high-temperature graphitizing organic fibers or low molecular hydrocarbon gas raw materials in an inert gas, carbon fiber is produced. A high degree of preferred alignment of the graphite lattice in the axial direction of the fiber will result in extremely high thermal conductivity. Ultra-high thermal conductivity materials made of carbon fiber and C/C composites use high thermal conductivity carbon fibers as their raw material. These materials have excellent performance in a number of areas, including high temperature strength, low coefficient of thermal expansion, good self-lubrication, and thermal conductivity.

In actuality, the greatest material's thermal conductivity isn't always the best material's thermal conductivity.

The product's structure, heat dissipation needs, product performance needs, and other factors should all fall under the area of thermal conductivity material selection.

You just need the thermal conductivity material that is best suited to your product, not the best thermal conductivity material available.
