Advantages and disadvantages of metal powder metallurgy

Metal powder metallurgy is an industrial technology that uses metal powder as raw material, through forming and sintering, to produce metal materials, composite materials and various types of products. Metal powder metallurgy technology has been widely used in transportation, machinery, electronics, aerospace, weapons, biology, new energy, information and nuclear industries. Powder metallurgy technology has a series of advantages, such as significant energy saving, material saving, excellent performance, high product accuracy and good stability, and is very suitable for mass production, so it has attracted the attention of the industry. What are the advantages and disadvantages of metal powder metallurgy? The following is a detailed introduction of the Zhongwei Precision Editor:

Advantages of metal powder metallurgy process:

1. The vast majority of refractory metals and their compounds, pseudoalloys, and porous materials can only be manufactured by powder metallurgy.

2. As powder metallurgy can be pressed into compacts of different sizes without or with little need for subsequent machining, it can greatly save metal and reduce product costs. When products are made by powder metallurgy, the metal loss is only 1-5%, while when products are made by general casting, the metal loss may reach 80%.

3. As the powder metallurgy process does not melt the material in the material production process, it is not afraid of mixing impurities brought by crucibles and deoxidizers. Sintering is generally carried out in vacuum and reducing atmosphere, and it is not afraid of oxidation and will not pollute the material, so it is possible to produce high-purity materials.

4. The powder metallurgy method can ensure the correctness and uniformity of the material composition ratio.

5. Powder metallurgy is suitable for the production of many products with the same shape, especially the products with high processing costs such as gears. The production cost can be greatly reduced by using the powder metallurgy method.

Disadvantages of metal powder metallurgy process:

1. The size of parts shall be considered when there is no batch.

2. The mold cost is relatively higher than the casting mold.

The above is the introduction of the advantages and disadvantages of metal powder metallurgy, hoping to help you better understand the metal powder metallurgy process
