Material Notes:
Information supplied by Ametek Specialty Metal Products.The material is available as finished parts with the following maximum dimensions:Width: 6 inches (152 mm)Thickness: 0.150 inches (3.8 mm)Length: 8 inches (203 mm)These composites of tungsten and copper have many applications in electronic devices. The excellent thermal conductivity and low thermal expansion makes them ideal for: chip mounting, heat sinks, circuit board cores, lids or covers, or thermal spreaders. The material can be machined into shapes and readily plated if required. AMETEK's wrought powder metallurgy composites have superior through-thickness thermal conductivity versus other products.
