What Is Tungsten Copper Brick?

Tungsten Copper alloy brick, is also called tungsten copper brick (tungsten-copper, Cu-W, or W-Cu) is a pseudo alloy of copper and tungsten. As copper and tungsten are not mutually soluble, the tungsten copper alloy brick material is composed of distinct particles of one metal dispersed in a matrix of the other one. The microstructure of tungsten copper brick is therefore rather a metal matrix composite than a true alloy.

Tungsten copper brick combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, highly thermally and electrically conductive, and easy to machine.Tungsten copper brick offered by us is high quality.

Parts are made from the Cu-W alloy by pressing the tungsten particles into a desired shape, sintering the compacted part, and then infiltrating with molten copper. Sheets, rods and bars of the alloy are available as well.

Commonly used tungsten copper brick alloy contains 10 to 50 wt. % of copper, the remaining portion being substantially tungsten. The typical properties of the tungsten copper brick alloy depend on its composition. The tungsten copper brick with less wt. % of copper has higher density, higher hardness and higher resistivity. The typical density of CuW90 alloy, with 10% of copper, is 16.75g/cm3 and 11.85g/cm3 for CuW50 alloy. CuW90 has higher hardness and resistivity of 260 HB kgf/mm2 and 6.5 µΩ.cm than CuW50.

Chinatungsten Online provides tungsten copper brick composites to be used extensively in thermal mounting plates, chip carriers, flanges, and frames for high-powered electronic devices. With the thermal advantages of tungsten copper brick with the very low expansion characteristics of tungsten, tungsten copper brick has properties similar to those of silicone carbide, aluminum oxide, and beryllium oxide. The thermal conductivity and low expansion also make tungsten copper brick an excellent choice even for extremely dense circuits. Tungsten copper brick can be widely used in many fields, we can provide different sizes of tungsten copper brick according to your requirements.
