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.
- Crom (CR): Provides corrosion resistance and improves oxidation resistance.
- Niken (NI): Enhances toughness, ductility, Và corrosion resistance.
- Nhôm (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, Và more reliable than many conventional alloys. The spherical shape of the powder ensures that it is ideal for sản xuất phụ gia processes, where flowability and packing density are critical for producing high-quality parts.
