Problems solved by technology

However, there is a small selection of reinforcements, and only reinforced metal matrix composites with a low content of reinforcement particles can be produced. When the content of reinforcement particles is large (> 15%), the fluidity of the melt is poor, the casting performance is poor, and molding is difficult.
