Personlized Products Hastelloy Material - Tungsten Copper WCu Heat Sink – Fotma
Personlized Products Hastelloy Material - Tungsten Copper WCu Heat Sink – Fotma Detail:
Description
Tungsten copper electronic packaging material has both the low expansion properties of tungsten and the high thermal conductivity properties of copper. What is particularly valuable is that its thermal expansion coefficient and thermal conductivity can be designed by adjusting the composition of the material brought great convenience.
FOTMA uses high-purity and high-quality raw materials, and obtains WCu electronic packaging materials and heat sink materials with excellent performance after pressing, high-temperature sintering and infiltration.
Advantages of Tungsten Copper (WCu) Electronic Packaging Materials
1. The tungsten copper electronic packaging material has an adjustable thermal expansion coefficient, which can be matched with different substrates (such as: stainless steel, valve alloy, silicon, gallium arsenide, gallium nitride, aluminum oxide, etc.);
2. No sintering activation elements are added to maintain good thermal conductivity;
3. Low porosity and good air tightness;
4. Good size control, surface finish and flatness.
5. Provide sheet, formed parts, also can meet the needs of electroplating.
