Product Description

ungsten-copper electronic packaging material has both the low expansion characteristics of tungsten and the high thermal conductivity of copper. What is particularly valuable is that its coefficient of thermal expansion and thermal conductivity can be designed by adjusting the composition of the material, thus giving the material its application Brings great convenience.

Our company uses high-purity and high-quality raw materials, after pressing and forming, high-temperature sintering and infiltration, WCu electronic packaging materials and heat sink materials with excellent performance are obtained.

Tungsten Copper (WCu) electronic packaging material advantages:

1. Tungsten copper electronic packaging materials have adjustable thermal expansion coefficients, 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, maintaining good thermal conductivity;

3. Low porosity and good air tightness of the product;

4. Good size control, surface finish and flatness.

5. Provide sheets and molded parts, which can also meet electroplating needs.
