For many years, Shanghai Bocote has focused on material research and continuously introduced new materials to solve the problems that arise in the user's use process from the root cause. For example, because drill-based alloys contain wear-resistant elements such as dock drills, they have high wear-resistant properties to fluid erosion such as mud. They are mostly used in high-end military technology fields such as aviation engines. We use them to manufacture turbine blade parts that are severely corroded by underground mud. Now the machining technology is mature, mold design, precision casting and processing of super hard materials have been independent, and the cost is controllable.
