Overview of 12Cr12Al5 Alloy Spherical Powder
What is 12Cr12Al5 Alloy Spherical Powder?
12Cr12Al5 Alloy Spherical Powder is an iron-based alloy that contains approximately 12% chromium and 5% aluminum. This specific combination of elements allows the alloy to form a protective aluminum oxide (Al₂O₃) layer when exposed to high temperatures, which makes it highly resistant to oxidation and corrosion.
The spherical shape of the powder is achieved through advanced atomization techniques, such as gas atomization, which ensures consistent particle size, excellent flowability, and uniform distribution. These characteristics make it ideal for 3D printing, thermal spraying, and other precision manufacturing techniques.
