Thermal conductivity - Import export

Extruded section, aluminium EN AW6060. Version Hard anodised aluminium, 50 µm. Hardness 500 HV. Note The aluminium guide rail has good thermal conductivity and importantly heats only at continuously very high speeds. ** lengths L2 = 20 mm * and L = 500 mm included L2 and L only available in full mm.

Centrifugally cast composite parts made up with a matrix in silicon-aluminum alloy and SiC reinforcement elements: Silicon Carbide particles. Characteristics of an ALUSiC® piece: - SiC reinforcement ratio ranging from 30 to 60% (in volume) depending on the application. - Perfect volume distribution of the SiC particles. Physical properties: - Low density (d ≤ 2.95). - Very low expansion coefficient (alpha < 8x10-6 with 60% SiC). - High thermal conductivity (> 150W/m/°K). Mechanical properties: - Very high stiffness (Proof stress > 185x10-6 N/mm² with 60% SiC). - Exceptional wear resistance. - Good mechanical properties under hot conditions (up to 300° C / 572° F). The non-reinforced zone has the characteristics of basic alloy.

Aluminium nitride is mostly used for its outstanding ability to dissipate heat, and together with its excellent electrical and mechanical properties, it is an advanced ceramic of choice for power electronics and microelectronics applications where heat must be dissipated. Selection of materials Microcertec offers two types of sintered alumininium nitride with a thermal conductivity of 180 W/m.K minimum : tape cast AlN (substrate), pressed AlN. A machinable aluminium nitride offering a thermal conductivity of 90 W/m.K is also available : ALN Shapal M –Soft™ Properties The main features of sintered aluminium nitride (AlN) are : excellent thermal conductivity low coefficient of thermal expansion good electrical insulation and resistivity low dielectric constant mechanical strength under compression load corrosion resistance (gas) Our typical applications Aluminium nitride is a ceramic material widely used in the following applications : heat sinks for uncooled high-power...
