The development history of powder metallurgy
May 15, 2018

The method of powder metallurgy actually comes from Powder metallurgy bearing.

Already a long time.In the early stage of human being, the powder of gold, silver, copper and bronze was used for the decoration of pottery.

In the second half of the 18th century and the first half of the 19th century, Russia, Britain, Spain and other countries have with preparing platinum sponge factory scale, through hot pressing, forging and moulding and sintering process manufacturing COINS and precious artifacts.

In 1890, the United States of coliji invented the powder metallurgy method to make light bulb with tungsten wire, which laid the foundation of modern powder metallurgy.

Until around 1910, it has been made by powder metallurgy method of molybdenum products, hard alloy, bronze, porous filters, oil bearing set brush and so on, gradually formed a complete set of powder metallurgy technology.
