This material isn’t just strong—it’s a workhorse with the ability to maintain its properties under extreme conditions, including high temperatures and stress.
In this comprehensive guide, we’ll explore every aspect of 18Ni15Co6.7Mo2Ti Spherical Alloy Powder, from its composition and properties to its applications, specifications, and pricing. Whether you’re an engineer, researcher, or manufacturer, this article will give you all the insights you need to make informed decisions about this incredible alloy.
What is 18Ni15Co6.7Mo2Ti Spherical Alloy Powder?
At its core, 18Ni15Co6.7Mo2Ti Spherical Alloy Powder is a maraging steel alloy that combines high-strength performance with ease of machinability. The name “maraging” comes from its strengthening mechanism—martensitic aging, which involves a heat treatment process to achieve exceptional mechanical properties. Its unique combination of nickel, cobalt, molybdenum, and titanium results in a material that is:
- Extremely strong and tough
- Corrosion-resistant in most environments
- Easily machinable pre-aging
- Highly stable, even under high stress or temperature
In its spherical powder form, this alloy becomes a versatile material for advanced manufacturing methods. Whether it’s being used to 3D-print aerospace components or create high-performance tooling, the flowability, uniform particle size, and high packing density of the powder ensure consistent results every time.
