Choosing the Right TC11 Powder: Factors to Consider

Selecting the optimal TC11 powder is crucial for achieving the desired performance and functionality in your final product. Here are key factors to consider when choosing TC11 powder for your application:

• Tamaño y distribución de partículas de polvo: The particle size and distribution of the powder can influence the flowability of the powder, how well it spreads evenly during AM, packing density, how tightly the particles pack together during AM, and ultimately, the mechanical properties of the final part. Finer powders generally result in higher density parts with improved mechanical properties, leading to stronger and more reliable components.
• Pureza del polvo: The purity of the TC11 powder is critical for ensuring the desired mechanical properties and corrosion resistance. Impurities, even in small amounts, can weaken the material, make it more susceptible to corrosion, and compromise its performance. High-purity TC11 powder ensures the material performs as expected, providing the strength, durability, and corrosion resistance required for demanding applications.
• Morfología del polvo: Spherical powder particles are generally preferred for AM processes as they offer good flowability, meaning they flow smoothly and consistently during powder handling and deposition, and packing density, resulting in more consistent and higher-quality parts with fewer defects. The shape and surface characteristics of the powder particles can impact the final part’s properties, so choosing the right morphology is essential for achieving the desired outcomes.
