Applied Nanotech, a nanotechnology company, has introduced an advanced version of CarbAl, which is a passive thermal management material.
The carbon-based material, CarbAl combines low thermal expansion coefficient, high thermal diffusivity and low density. The exceptional qualities of CarbAl will surpass the potential of traditional thermal management materials such as aluminum and copper. The functionality and durability of CarbAl has been enhanced by surface coatings and electroplating. This material can help electronics manufacturers for maintaining the temperature within specified limits.
CarbAl is a lightweight material and its thermal performance is increased, when compared to its counterparts. The density of CarbAl is 1.75 g/cm3. CarbAl has lower thermal conductivity of 350 W/mK, when compared to copper with 390 W/mK. The thermal diffusivity of CarbAl is around 2.9 cm2/sec. CarbAl material has a higher CTE.
This carbon-based material is honored by R&D Magazine as one of the important product innovations. The company has included functional surface coatings like dielectric layers and metal plating to its CarbAl, which can be electroplated using nickel, copper, gold and nickel boron. Addition of aluminum plates and soldered copper increases the stability and strength. CarbAl has full circuit trace functionality and a dielectric layer.
CarbAl material is available in custom shapes and dimensions, according to the applications specified by the customer.
