As we all know, lightning is enormously destructive, it produces a powerful current. According to research, the most common linear lightning has a current intensity of tens of thousands to 200,000 amps. Lightning can also cause extreme high temperatures, which can easily lead to forest and house fires. Therefore, in thunderstorms, we often see some towering trees being knocked down by lightning, and some buildings were damaged by lightning. But there are also some buildings that are safe and sound.…
Except Rockwell hardness (HRB) of detection, it is essential that electrical conductivity measuring in tungsten copper composite materials as heat sink materials. Electrical conductivity is an important indicator to measure ability to conduct electricity of tungsten copper heat sink, which directly affects the final properties of products. The stronger ability to conduct electricity, the smaller electrical resistance, on the contrary, electrical resistance is greater. For hardness testing, if tungsten copper material over-burning, the inside Cu phase will exude and lead…
After material preparation and injection, the following steps are degreasing and sintering. Degreasing process is also known as forming agent or binder removal, which is the use of physical or chemical methods the added binder (such as alcohol, paraffin and the like) were removed. It needs the longest time of PIM and is the most difficult to control. Improper operation will cause the deformation or uneven component defects of tungsten copper blank, which will affect the final properties of tungsten…
Based on conventional molding process and combines plastic molding industry technology, PIM (Powder Injection Molding) has excellent applicability in some tungsten copper products with small size and complex shape or structure. So we study from mixing, injection, degreasing, sintering and several key process of tungsten copper powder injection molding, and analyze and summarize the advantages of the process and the defects. The first is the selection of the binder and the preparation of mixture. Binders can reduce caking of the…
Tungsten-copper composite sintered body directly affects the comprehensive performance of final product so that the determination of the relative aspects of density, hardness, conductivity, shrinkage, scanning electron microscopy and crushing strength becomes essential. Next, we will combine the experience of some relevant theoretical principles and production practices as summarized in one by one analysis of the test method. Relative Density Test: It usually uses Archimedes drainage method, which weighs tungsten copper sintered in the air and in distilled water separately…
