Tungsten copper alloy is a composite of tungsten and copper. The coefficient of thermal expansion (CTE) of the composite can be designed by controlling the content of tungsten, matching that of the materials, such as Ceramics (Al2O3,BeO)、Semiconductors (Si)、Metals (Kovar),etc. The products are widely applicated in the fields such as radio frequency、microwave、high power diode packaging and optical communication system.

It is a composite made from Mo and Cu, Similar to W-Cu, CTE of Mo-Cu can also be tailored by adjusting the composition. But Mo - Cu is much lighter than W – Cu, So that it is more suitable for aeronautic and astronautic applications.

Cu/Mo/Cu (CMC) is a sandwich composite including a molybdenum core layer and two copper clad layers. It has tailorable CTE, high thermal conductivity and high strength. All types of Cu/Mo/Cu sheets can be stamped into components.

Cu/Mo70Cu/Cu is a sandwich composite like Cu/Mo/Cu including a Mo70-Cu alloy core layer and two copper clad layers. The ratio of the thickness in Cu:Mo70Cu:Cu is1:4:1. It has different CTE in X and Y direction, higher thermal conductivity than that of W(Mo)Cu、Cu/Mo/Cu and more cheap. All types of Cu/Mo70Cu/Cu sheets can be stamped into compoents.

Equivalent to GB 4J29, ASTM F15, UNS K94610);KOVAR is a hard glass iron base sealing alloy containing 29% nickel and 17% cobalt.

Oxygen free copper without hydrogen embrittlement, high conductivity, good machining and welding properties, corrosion resistance and low temperature performance.Different countries have different standards for oxygen content.Anaerobic copper is pure copper without oxygen and without any deoxidizer residue, with a density of 8.9(g/cm3).
