Among these, CoCrNiAlTi Spherical HEA Powder stands out as a versatile and high-strength material designed for the most demanding applications. This alloy, composed of Cobalt (Co), Chromium (Cr), Nickel (Ni), Aluminum (Al), and Titanium (Ti), offers outstanding mechanical properties, excellent corrosion resistance, and high-temperature stability.
The spherical form of this powder is particularly suited for additive manufacturing and powder metallurgy, where flowability and packing density play critical roles in ensuring part integrity and performance. Whether you’re in the aerospace industry looking for materials that can withstand extreme environments or a manufacturer aiming to produce parts with high precision and durability, CoCrNiAlTi Spherical HEA Powder is the answer.
In this article, we’ll cover everything you need to know about CoCrNiAlTi Spherical HEA Powder—from its composition and properties to its applications, pricing, and more. We’ll also compare it with other materials to help you understand why this alloy might be the best choice for your high-performance needs.
What is CoCrNiAlTi Spherical HEA Powder?
Understanding High-Entropy Alloys (HEAs)
Let’s start with the basics. High-Entropy Alloys (HEAs) are a relatively new class of materials made from a mixture of five or more elements in near-equal proportions. This is different from traditional alloys, which typically have one or two primary elements. The result? A material with higher stability, improved mechanical properties, and an ability to withstand extreme conditions.
Composition of CoCrNiAlTi Spherical HEA Powder
The CoCrNiAlTi Spherical HEA Powder is made up of five key elements, each contributing specific properties to the alloy:
- Cobalt (Co): Adds magnetic properties and increases wear resistance.
- Chromium (Cr): Provides corrosion resistance and improves oxidation resistance.
- Nickel (Ni): Enhances toughness, ductility, and corrosion resistance.
- Aluminum (Al): Reduces the density of the alloy and adds oxidation resistance.
- Titanium (Ti): Contributes to strength and hardness, making the alloy more resistant to deformation.
The combination of these elements results in a material that is stronger, more durable, and more reliable than many conventional alloys. The spherical shape of the powder ensures that it is ideal for additive manufacturing processes, where flowability and packing density are critical for producing high-quality parts.
Key Properties of CoCrNiAlTi Spherical HEA Powder

Why the Spherical Shape Matters
The spherical shape of the powder is not just a manufacturing convenience—it’s a game-changer when it comes to additive manufacturing and powder metallurgy. Spherical powders have better flowability, which means they can be evenly spread in thin layers, improving the final product’s surface finish and mechanical properties. Additionally, these powders pack more densely, which results in stronger, more reliable parts.
