FAQ
Why use 0.7-grain size tungsten carbide powder to make helix carbide rods instead of 0.6?
1. Enhanced Toughness: The larger 0.7 grain size can also lead to improved toughness of the tungsten carbide material. This enhanced toughness can make the helix carbide rods more resistant to cracking or breaking under high stress or impact loads.
2. Better Machinability: The 0.7-grain size may offer slightly better machinability compared to the finer 0.6-grain size. This can make it easier to shape and form the helix carbide rods during the manufacturing process.
3. Application-specific Requirements: Depending on the specific application and performance requirements of the helix carbide rods, the 0.7-grain size may be better suited to meet the desired properties, such as strength, wear resistance, or thermal conductivity.
