Nejčastější dotazy
What’s the difference between zirconium and zirconium alloy powder?
Pure zirconium powder consists of only zirconium metal, while zirconium alloy powder combines zirconium with other alloying elements like nickel to enhance properties.
What particle size is best for 3D printing zirconium nickel alloy powder?
A particle size range of 10-45 microns is typical for powder bed fusion 3D printing with zirconium nickel alloys.
Is zirconium nickel alloy powder radioactive?
No, zirconium nickel alloy powder contains stable isotopes and is non-radioactive, unlike some zirconium products used in nuclear applications.
What precautions should be taken when handling zirconium nickel alloy powder?
Avoid contact with skin and eyes. Wear PPE including gloves, safety glasses, and masks to minimize exposure and inhalation during handling. Use spark-proof tools and equipments. Powder may be flammable.
Can you 3D print zirconium nickel alloy parts without hot isostatic pressing?
Yes, but properties are enhanced with post-processing via HIP to fully densify any internal porosity and improve mechanical performance.
