The theoretical MIM powder: powder size is 2～8μm;bulk density is 40%-50%;tap density is more than 50%;powder particles is nearly globose, larger than the surface.
micro structure of metal powder(1*2500)
At present,MIM metal raw material including iron, nickel,titanium,stainless steel and etc.And also it has development for diversification,such as structure material, function material,magnetic material and so on.
The way of production MIM powder mainly have Carbonyl method , ultra-high pressure water atomization method, high pressure gas atomization, plasma atomization, and laminar atomization.The different technology of manufacture powder have different influence to powder size,particle structure,micro structure,chemical property,manufacture cost and so on.
