Properties: 

High temperature resistance, corrosion resistance, oxidation resistance, easy processing, 

rapid heat absorption and heat release and other properties.

Main uses:

1. Excellent corrosion resistance

Hafnium powder has excellent corrosion resistance and can be compatible with a wide 

range of chemicals. It resists corrosion in acidic and alkaline environments and remains 

stable under high temperature and pressure conditions. Therefore, hafnium powder is 

often used to prepare materials and coatings with high corrosion resistance requirements.

2. High strength and low density

Hafnium powder is a material with high strength and low density, which makes it an 

ideal raw material for the preparation of lightweight, high-strength alloys. For example, 

hafnium powder can be mixed with metals such as titanium and magnesium alloys to 

increase the strength and hardness of the alloy and reduce the overall weight. This is 

particularly widespread in the aerospace and automotive industries.

3. Good thermal and electrical conductivity

Hafnium powder has good thermal and electrical conductivity, making it an important 

raw material for the preparation of thermal conductive devices and conductive materials. 

Hafnium powder can be used to prepare efficient devices such as heat sinks, heat exchangers 

and sensors to meet the needs of different fields. In addition, hafnium powder has a relatively 

low refractive index and transparency to electromagnetic waves, so it can also be used to 

prepare electromagnetic shielding materials.

4. Biocompatibility

Hafnium powder has good biocompatibility and does not cause significant toxicity and 

allergic reactions to the human body. This makes it widely used in the medical field. Hafnium 

powder can be prepared to corrosion resistant artificial joints, dental implants and vascular 

stents, etc., to help people restore health.

5. High temperature stability

Hafnium powder has good high temperature stability and can maintain stable mechanical 

properties and chemical stability in high temperature environment. This makes hafnium 

powder widely used in aviation, aerospace and energy. For example, hafnium powder can 

be used to prepare superalloy materials and refractories to meet the requirements of use 

under extreme conditions.
