the Specifications of Pó de Inconel

The properties of Inconel powder vary depending on the specific alloy composition, particle size, and manufacturing process. Here’s a deeper dive into the nitty-gritty details:

Tamanho e distribuição de partículas:

The size and distribution of Inconel powder particles significantly impact the quality and properties of the final 3D printed part. Generally, finer powders (in the range of 15-45 microns) produce smoother surfaces and intricate details, but they can also be more challenging to flow freely during the printing process. Conversely, coarser powders (45-100 microns) offer better flow characteristics but might result in a slightly rougher surface finish. The ideal particle size depends on the specific 3D printing technology and the desired outcome.

Spherical Shape:

As mentioned earlier, the near-perfect spherical shape of Inconel powder particles is crucial for optimal performance. This shape ensures consistent flow during printing, minimizes voids within the finished product, and contributes to its overall strength.

Fluidez:

Flowability refers to the ease with which powder particles move and pack together. Good flowability is essential for achieving a uniform and dense layer during the 3D printing process. Factors like particle size distribution, surface texture, and moisture content can all influence flowability.

Densidade Aparente:

Apparent density refers to the weight of powder per unit volume, taking into account the spaces between particles. It’s a crucial parameter for determining the amount of powder needed for a specific 3D printing job. The apparent density of Inconel powder can vary depending on the alloy composition and particle size.
