Application of powder metallurgy material for iron powder

In powder metallurgy industry, high purity iron powder is dosage is the biggest, the most widely used metal powder, accounting for the powder metallurgy injection with 70% of the amount of powder can be said of high-purity iron powder production technology, scale, variety and quality in a certain extent, reflect the overall development of powder metallurgy industry.

Compared with tiejingfen, regardless of price, market performance, high performance materials, metal powders have the incomparable advantages. Emerging metal materials are made from metal powder, powder metallurgy make its performance has been greatly changed. For example, molten steel and molten iron at high temperature is difficult to mix together, but the two are easy to mix together, and the metal structure will be changed, the more resistant to high temperature, resistance to cold.

At present, the high-purity iron powder production method mainly [reduction method, spraying method, electrolysis and carbonyl]. The reductive method is low cost, large output, low energy consumption, and has porous morphology, irregular, good formability and green strength is high pressure, in the production of auto parts, compressor parts, sintered bearing, electric tool parts and electronic components such as become irreplaceable raw materials, so the reduction method is one of the main production technique of high purity iron, reduced iron powder has been powder metallurgy industry the main raw materials.
