Product Name: MetGraf™ Thermal Management Products

Product Description

Overview Electronics thermal management technology is revolutionizing the way the world communicates and conducts business. Today’s products, from cellular phones to sophisticated imaging satellites require innovative composite materials that provide more functionality in less volume. Electronic systems must dump large amounts of waste heat more effectively and balance thermal stresses created by dissimilar materials. MetGraf composites are lightweight, high thermal conductivity, low thermal expansion graphite fiber reinforced aluminum and copper alloys ideally suited for heat sinks, base plates, carrier plates, and thermal spreaders. Aluminum Graphite Composites MetGraf composites are cast as plate, machined to print and plated with Ni, Au, or Ag. MetGraf is a high speed machining material into complex shapes to tight tolerances and surface finish. MetGraf is in production for military and commercial applications, including wireless communications, power semiconductor, satellite, and semiconductor equipment. MetGraf is a candidate for matched thermal expansion (CTE) applications that require high thermal conductivity. MetGraf can be designed into new systems or used to replace traditional thermal management materials like molybdenum, iron-nickel alloys (Kovar), aluminum silicon carbide, aluminum silicon, copper tungsten, copper moly, aluminum, or copper. MMCC offers four "standard" aluminum graphite products for thermal management based on the CTE required (2-10 ppm/C). Custom products can be made (and have been made) for special requirements. Copper Graphite Composites MMCC now offers Cu MetGraf 7-300 copper graphite composites for thermal management. Copper graphite has excellent thermal conductivity and is 62% lighter than Cu/W. Copper graphite is a high speed machining material to tight tolerances and surface finish. Plating specs: Electroless Ni - MIL-C-26074E , Electrodeposited Au - MIL-G-45204C.
