Bronze powder is an important raw material for the production and use of powder metallurgy. International production of bronze powder began at 20 century. The production methods used at that time are restoring copper oxidation and electrolysis. After 1950s, there are new production methods for bronze powder: replacement precipitation and hydrometallurgy method. Then the atomization method emerges.

In 1958 China began the process of bronze powder (FCu 663). The production time of bronze powder electrolytic test. In mid 1960, the successful experience of electrolytic bronze powder and small-scale production. Mid-1970, China has established a production line for the bronze powder electrolytic before. 1980 and 1990, with the rapid development of China's economy grew bronze powder. In order to market demand, a number of large companies with the potential for innovation and technological change, the production of bronze powder, respectively. We also created and developed more than l0 manufacturer of bronze powder, bronze powder 4000T household, the average annual production of about 1400T.

An alternative to electrolysis for the production of brass powder, when the grinding weakened sputtering. Experience has shown that no spraying of the powder bulk density of bronze and the lack of low plasticity in practice replaced by a bronze powder electrolyte. Therefore developed the use of sprinklers, in combination with additional treatment, such as environmental requirements oxidation-reduction under conditions of low bulk density powder, bronze.

The industrialization process, the fine mist spray powder bronze method of water and gas. Experience has shown that the production affects the production of water spray of gas atomization. The size of the particles and the particle size distribution of the water jet, bronze powder, and the sputtering gas, is that the same treatment conditions, the effects of oxidation and the apparent density of the final product is different. Have studied the causes of water spray in the form of dust particles as an irregular spray of powder, and therefore more favorable to the oxidation rate higher.

Oxidation in the production of high performance and a low density set of brass powder without a great size. He claims that the oxidation time, oxidation and oxidation of the powder oxidative effect has a significant impact on production. In particular, the time-temperature oxidation and the oxidation of the addition, the oxidation relates in particular to the oxidizing power. The oxidation process is divided into static and dynamic in two ways. Static oxidation of the oxidation of metal powder is very slow and subject to agglomeration, the oxidation is not dynamic, so that the effect of oxidation is very good. As part of the state 5000C/3h, oxidation resistance static oxidation of the dynamics of bronze powder in 7.5% oxygen, the density 3.80g/cm3, the dynamic stability against oxidation, the oxygen content of bronze powder is 18.7%, density of 2.32 g / cm3.

AOR method for the manufacture of bronze powder, due to the irregular shape of a microscope, hypoxia, good flexibility, and productivity of the process stability, and may be replaced by a powder of electrolytic copper. Requires more friction materials based on products of iron and green are the resistance of carbon powder metallurgy of coal more reliable companies that use electrical use and spread, the effect is very satisfactory.

AOR bronze powder with antioxidant effects of electrolytic copper powder under the same conditions, an antioxidant effect AOR bronze powder 1 times the electrolytic copper powder. This diamond tool manufacturing company is particularly important, since these are bronze powder, a small amount, which requires a long period of dust.
