WCu Copper Tungsten AlloyTungsten Copper Heat Sink with 20 wt.% Cu

Description:

Tungsten copper heat sink is a composite of tungsten and copper, so both the thermal advantages of copper and the very low expansion characteristics of tungsten can be adjusted to meet different requirements.

Advantages:

1. Excellent flatness, surface finish, and size control

2. Semi-finished or finished (Ni/Au plated) products available

Product Properties:

Grade	W Content	Density g/cm³	Coefficient of thermal Expansion ×10^-6(20℃)	Thermal conductivity W/(M·K)
90WCu	90±2%	17.0	6.5	180 (25℃) /176 (100℃)
85WCu	85±2%	16.4	7.2	190 (25℃) / 183 (100℃)
80WCu	80±2%	15.65	8.3	200 (25℃) / 197 (100℃)
75WCu	75±2%	14.9	9.0	230 (25℃) / 220 (100℃)
50WCu	50±2%	12.2	12.5	340 (25℃) / 310 (100℃)

Application:

They are extensively used as thermal mounting plates, chip carriers, tungsten copper flanges, and frames for RF, light emitting diodes and detectors, laser diode packages like pulse, single emitter, bars and complex carriers for optoelectronics amplifiers, receivers, transmitters, tunable lasers, etc.
