|Title: Development, Properties, and Applications for a High Thermal Conductivity Sintered Aluminum Material New advancements in Powder Metal (PM) sintered aluminum have raised the bar for thermal conductivity in heat sink design. A new PM alloy, TC-2000, relies on a low level of alloying and sinters close to theoretical density yielding a high thermal conductivity. This sintered material possesses a thermal conductivity exceeding 240 w/m-k, which makes it unique in the marketplace where cast, extruded, and forged aluminum materials range from 80 – 205 w/m-k. Another advantage with powder metal sintered aluminum is the elimination of machining due to the near net shape capabilities of PM manufacturing, minimizing cost. This unique combination of low cost and high thermal conductivity makes this material an attractive alternative to higher cost materials such as copper. Properties and application for this material will be presented.|
