Hafnium Metal (Hf)

Hafnium Metal Specifications

How to Select Hafnium Metal for Your Application

Select the Required Product Form

Choose the hafnium form according to your processing method and end use. Crystal bars or rods may be appropriate for further processing and specialized material applications, while granules or pellets can suit smaller-scale material use, and sputtering targets are designed for thin-film deposition.

Confirm Purity and Zirconium Content

Do not evaluate hafnium only by total purity. Because zirconium is closely associated with hafnium, confirm both the specified Hf + Zr purity and maximum Zr content when these parameters are important to your application.

Specify Dimensions

For rods, bars, targets, or other processed forms, provide the required diameter, length, thickness, shape and dimensional tolerance where applicable.

Define Quantity and Application

Providing the intended application and required quantity helps us evaluate the appropriate product form and specification more efficiently.

Confirm Documentation Requirements

If your procurement process requires a COA, material analysis, packaging requirements, or other documentation, include these requirements with your inquiry.

Hafnium vs Zirconium

Hafnium and zirconium frequently occur together in nature and have very similar chemical properties, making their separation technically challenging.

For this reason, a hafnium specification may state both the combined Hf + Zr purity and a separate maximum Zr content.

The appropriate zirconium limit depends on the product form and application. Buyers sourcing high-purity hafnium should therefore review the actual Zr specification rather than relying only on a general purity percentage.

Zhiyue provides different hafnium products with product-specific purity and zirconium specifications. Contact us if your application requires a particular Zr limit.
