Copper content of the iron - copper compound powder and its production

摘要

In the mixed powder of the copper coating iron powder or the copper coating iron powder and the electrolytic copper powder, copper content is 45 - 70wt%, apparent density above 2.2g/cm3, plates the copper in the iron - copper compound powder, and the iron powder which for metal ceramic, designate the copper coating iron powder which features that fluidity is below 25s/50g as the main component mixes this copper coating iron powder independence or the copper coating iron powder and the electrolytic copper powder, you sinter and the copper coating iron powder which features that pulverize the powder where copper content is 45 - 70wt% the main componentProduction method of the iron - copper compound powder for metal ceramic which it does. It improves the flowability and apparent density of the sinterring raw materials powder at the time of the production of the raw materials powder for metal ceramic which designates the copper coating iron of business such as oil-impregnated sintered bearing as the main component, improves sinterring quality such as pressure ring strength, furthermore cost it designates that it reduces as topic.
