Metal Powders

Metal powders are commonly used in practical applications such as printing, painting, powder metallurgy, additive manufacturing, and surface coating. The characteristics of the base powder determine how the finished products perform in any given application. To ensure the repeatable manufacture of metal parts, metal powders must exhibit consistent powder characteristics. Therefore, it is essential to accurately measure size and shape of metal particles.

 

1. Particle shape

Particle shape influences powder packing, powder flowability and, indirectly, the sintering of compacts made from these powders.

 

2. Particle size and size distribution

Particle size and particle size distribution are key indicators for certifying and monitoring the quality of metal powders before first use and during powder recycling.

In addition, the powders’ properties (bulk density, flowability, surface area, compressibility) and the potential applications are also affected by these characteristics. Therefore, it is necessary to adequately elucidate these characteristics.
