From the price point of view, the price of natural diamond wire drawing dies must be a bit more expensive, but there is a reason for it to be expensive, because this type of wire drawing die itself is more complicated in processing. Of that kind. The natural diamond wire drawing die has very high-quality hardness, but it is easy to cause friction, so this type of wire drawing die can only be used on some materials with a relatively small diameter, but its wear resistance is the best.

There is also a cemented carbide die. The hardness of this film is relatively low, and the surface is not very rough, but its wear resistance is relatively poor, and its hardness is relatively low, usually it is not recommended to buy of. Choosing a wire drawing die is like choosing an explosion-proof electric heater. You have to be very careful. Only if you pay attention to it, it will return you a piece of peace of mind.
