What is the most prominent aspect of powder metallurgy?
1. Capable of manufacturing materials and products that cannot be made or difficult to be made by other processes at present, such as porous materials and products, sweat, shock absorption, sound insulation, refractory metal materials and products such as tungsten, aluminum, titanium, metal-plastic, bimetal and other composite materials and products.
2. Can directly produce products that meet or close to the size requirements of finished products, so as to reduce or cancel mechanical processing, the material utilization rate can be as high as 95%, it can also replace steel with iron in some products, so as to save material and energy.
