Base on different application of the users, tungsten carbide bushes are usually made of different tungsten carbide grades. The major two series of tungsten carbide grade is YG series and YN series. Generally speaking, YG series tungsten carbide bushes have higher transverse rupture strength, while YN series tungsten carbide bush resist corrosion better than the former one. For its specific uses, tungsten carbide bushes are often made with high accuracy, and owing to their perfect finish, precise dimension, durability and corrosion resistance, these are highly appreciated by the clients all around the world. And the followings are the finished tungsten carbide bush and blank ones: RenQiu HengRui Tungsten Carbide can make as per your request, once detailed application and drawing can be provided.
