Powder metallurgy is a manufacturing process that involves creating metal parts from powdered materials. The process typically includes mixing metal powders, compacting them into a desired shape, and then heating them in a furnace to bond the particles together. This method allows for precise control over the material properties and shapes of the final product. One of the main advantages of powder metallurgy is its ability to produce complex shapes that would be difficult or costly to achieve with traditional machining methods. Additionally, it can minimize waste, as excess material can often be recycled back into the process, making it a more sustainable option for producing metal components.
