Metal powder is a tiny granular substance made of metal elements or alloys. Metal powder has high specific surface area, good physical and chemical properties and a wide range of applications. The following are some common types of metal powders and their characteristics.

1. Aluminum powder
Aluminum powder is an important metal powder with good conductivity, strength, corrosion resistance and high specific surface area. Aluminum powder can be used to make automotive parts, electronic components, fireworks, fuel, etc.

2. Copper powder
Copper powder is another common metal powder with excellent performance. It can be used to make electrical equipment, electrical components, metal paint, photographic equipment and consumables, friction materials and smelting, etc.

3. Iron powder
Iron powder is an important metal powder. Iron powder is usually used to produce powder metallurgy parts, metal injection molding parts, soft magnetic materials, etc. In addition, iron powder can also be used to make electromagnets, motors, generators, batteries, controllers, etc.

4. Tungsten powder
Tungsten powder is an excellent metal powder. It is a yellow tiny particle that can be used to make electronic parts, thermal reactors, tungsten alloy materials, high-temperature thermal imaging devices, etc.

5. Nickel powder
Nickel powder is a common metal powder with high corrosion resistance and oxidation resistance. Nickel powder is usually used to make fireworks, magnetic equipment, optical films, catalysts, etc.

6. Zinc powder
Zinc powder is a metal powder with good physical and chemical properties. It can be used to make galvanized steel plates, zinc alloys, optical films, batteries, etc.

7. Silver powder
Silver powder is a precious metal powder with excellent electrical conductivity, thermal conductivity and chemical stability. Silver powder can be used to make circuit boards, electronic devices, solar cells, gas-sensitive materials, etc.

8. Titanium powder

9. Zirconium powder Zirconium powder is a high-temperature stable metal powder with good corrosion resistance and mechanical properties. Zirconium powder can be used to make aircraft engine parts, petrochemical anti-corrosion and other fields.

In short, there are many types of metal powders, each with its own unique physical and chemical properties and application fields. For different production processes and application requirements, different types of metal powders can be selected for processing or application,
