Metal powders requirement for particle size control
The metal powders strength means Fine degree of powder, The original standard is the metal particles through the course of a square inch , the greater numbers, the smaller particles. Binding surface with objects will be better.
Generally speaking, the smaller particle size, sintering or cast products is more exquisite, the quality is also higher, but the smaller particle size, sintering temperature and time are available to the strict, otherwise there will be burnt metal particles and oxidation, will affect the quality of products.
So particle size measurement and control is a very important point for improving metal powder products quality.
For example, when use laser particle size analyzer test, because the copper powder is with a large proportion, without ultrasonic testing, need to complete the test as soon as possible, In case that cooper powders precipitation in pipe effect particle size distribution accuracy.
