Features and uses
1. Traditional powder metallurgy and injection molding:
For high specific gravity alloys in traditional powder metallurgy, it is necessary to select more active iron powder as the liquid phase in sintering to form a more continuous binder phase, suppress the generation of brittle phases, and then obtain high-density or fully-fine high-function products . The primary use in military projects is to replace the now banned depleted uranium materials to produce armor-piercing projectile cores. In the injection molding process, the maximum powder filling amount is very high. Therefore, the loose density requirements in the powder specification are very high. However, the smaller the particle size of the powder, the more prone to arching phenomenon and the lower the loose density. In this case, it is very important that the particles do not stick. It was not until the German BASF company developed a proprietary brand that injection molding was truly used in industry.
2. Iron powder core:
Because of its small particle size (below 10um), large activity, and irregular shape (onion head layered structure), carbonyl iron powder has a high magnetic flux rate under high frequency and ultra high frequency, and is also widely used in the manufacture of magnetic materials. It has an irreplaceable effect in the manufacture of high-frequency iron powder cores. The American Micrometals company is the specification maker in this category. Many of the company's products are manufactured based on the carbonyl iron powder provided by the German BASF company.
3. Diamond tools:
Traditional high-performance diamond tools use expensive cobalt powder as the matrix. Recent research and production indicate that the use of carbonyl iron powder to reduce the amount of Co powder can also achieve a reasonably high function. In addition, for traditional iron-based diamond tools, the use of carbonyl iron powder can improve the manipulation force of the matrix on the diamond and improve the wear resistance of the matrix.
4. Diamond catalyst:
There is no market in my country for the catalysts that make up diamonds.
5. Nutrient iron supplementation:
The carbonyl iron powder produced by American ISP has been officially approved by the U.S. Drug Administration and can be directly added to food as an iron supplement. The current data indicate that the absorption rate of carbonyl iron powder by the human body exceeds 80%, which is far beyond the currently used compound iron supplements. At the same time, the use of carbonyl iron powder will not cause excessive iron poisoning. There is no domestic information indicating that the government has allowed carbonyl iron powder to be used as a nutrient iron supplement.
6. Microwave absorption data:
The application of carbonyl iron powder in the field of national defense. According to the data, the research on carbonyl iron powder absorption data in the 1990s is very quick.
