Product Description
High activity composite powder prepared by our company is characterized by its high sintering shrinkage performance. It is often used to produce two types of heat sink materials with significantly different melting points, such as mixed powder blank pressing of tungsten copper and molybdenum copper metal powders, injection molding, and other production processes.
Production information
| | | |
| Highly active composite W-Cu powder | Traditional process W-Cu powder | The morphology of the spherical powder under 1000 times scanning electron microscope | The morphology under 200 times scanning electron microscope. |
Unlike traditional powders, our composite powders which closely fitting their molecules at the compound stage, spherical oxide powder of two-phase metal is obtained.
After reduction, the spherical structure is broken, forming a particle size of 0.8-1.3 μ M of irregular powder.
Taking W80-Cu20 as an example, when using this powder to directly press and prepare billets, compared to traditional processes, there is no need for burn-in and infiltration. After molding, it can be directly degummed and sintered in one step in a chain furnace, with a sintering density of over 99.5%. It has great advantages in saving energy, time, and improving production efficiency.
Our company can customize W-Cu, Mo-Cu and other multiple metal composite powders with different compositions and proportions according to customer needs.
