Aluminum alloy precision ring forgings take metal powder as raw material, and the production process of metal materials, composite materials and various products adopts mold forming and sintering. The following are the advantages and disadvantages of precision ring forgings:
advantage:
1. The utilization rate of materials is very high, reaching more than 98%;
2. Less or no cutting, low cost;
3. It is suitable for large-scale production, with high precision and good consistency of molded products;
4. Porosity, which can control porosity, can be used for porous materials and oil-bearing;
5. Special materials and products can be produced.
Disadvantages:
1. High cost of raw material powder;
2. It requires the use of molds, with large one-time investment;
3. Small batch size and high production cost;
4. The production equipment is expensive;
5. Due to the use of molds and pressure machinery, the size and shape of products are limited;
6. Affected by pores, the mechanical properties are worse than those of dense metal materials.
