The Advantages of Tungsten Copper Heat Sinks:

Tungsten copper alloys are widely used in electric, semiconductor, Machinery, metallurgy and other industries. Especially in semiconductor industries, the low coefficient of thermal expansion (CTE) and high thermal conductivity make these alloys the first choice for high power LD modules.

The Properties of Tungsten Copper Alloys:

Materials	Density (g/cm3)	CTE (ppm/K)	Conductivity (MS/m)	TC (W/mk)	Applications
W85Cu15	16.0~16.5	7.2	19	195~210	Contact/ Packaging/ Cathode
W80Cu20	15.1~15.5	8.2	23	200~220	Contact/ Packaging/ Electrospark
W70Cu30	13.7~14.2	9.4	25	220~240	Contact/ Packaging/ Electrospark/ Electrode
