PropertyBrief IntroductionW-Cu heat sink material is a composite of tungsten and copper, with both tungsten low expansion characteristics, but also has copper of high thermal conductivity properties, and the tungsten and copper in the thermal expansion coefficient and thermal conductivity can be adjusted with the W-Cu composition, also the composite can be machined to various shape, these features make the application of this composite with great convenience.1) high melting point, high strength,2) smooth and clean surface,3) good conductions, small linear expansion coefficient and goodheat-resistance3.Chemical compositionMaterialWCu%Tungsten ContentHardnessHBg/Density at 20ºCW/M.KThermal conductivity at 25ºC(10-6/k)Coefficient of thermal expansion at 20ºCW90Cu109026017.0180-1906.5W85Cu158524016.4190-2007.0W80Cu208022015.6200-2108.3W75Cu257519514.9220-2309.0W50Cu505012512.2310-34012.54.Property of high tungsten alloy WNiCu, WNiFeAMST 21014 class 190%WNiFe, 90%WNiCuDensity : 17.0Hardness: 32HRC maxElongation: 5-20%AMST 21014 class 292.5%WNiFe, 92.5%WNiCuDensity : 17.2Hardness: 33HRC maxElongation: 5-15%AMST 21014 class 395%WNiFe, W95NiCuDensity : 18.0Hardness: 34HRC maxElongation: 3-10%AMST 21014 class 497.5%WNiFe, W97.5NiCuDensity : 18.85Hardness: 35HRC maxElongation: 1-8%5.
