Powder metallurgy products are forming and sintering process of metal powder (or metal powder and non-metallic powder mixture) made of materials and products of the technology. It is a branch of metallurgy and materials science.

Powder metallurgy products from a wide range of applications, from general machinery manufacturing to precision instruments; from hardware to large machinery; from the electronics industry to the motor manufacturing; from the civilian industry to the military industry; from the general technology to cutting-edge high-tech, can see Powder metallurgy process of the figure.

Powder metallurgy development history:

Powder metallurgy method originated in three thousand years BC. The first method of making iron is essentially a powder metallurgy method.

The development of modern powder metallurgy technology has three important signs:

1, to overcome the refractory metal casting process of the difficulties. 1903 manufacturing tungsten wire, to promote the development of powder metallurgy; 1923 powder metallurgy carbide appears as the revolution in mechanical processing.

2, the thirties successful preparation of porous oil bearing; then powder metallurgy iron-based mechanical parts development, give full play to the powder metallurgy less cutting or even no cutting advantages.

3, to the more advanced new materials, new technology development. In the late 1940s, powder high-speed steel and powder superalloys appeared in the late 1960s and early 1970s.
