Efficient conductivity and oxidation resistance, the application field of flake silver coated copper powder continues to expand

Sheet shaped silver foil copper powderIt is a metal powder material commonly used in the preparation of electronic packaging materials, conductive pastes, high-temperature lubricating materials, etc. Due to the good conductivity and weak oxidation of silver, while the addition of copper can improve the mechanical strength and corrosion resistance of the material, this composite material has been widely used in the electronics industry, aerospace and other fields. In addition, sheet-like silver coated copper powder can also be used for preparationConductive adhesiveHigh temperature ceramics and other materials.

1、 Silver foil copper powder is widely used in daily products. Here are some examples:

1. Electronic products: Sheet silver coated copper powder can be used for preparationConductive pasteConductive adhesives and films used in electronic products such as mobile phone screens, LCD displays, capacitors, etc.

   
   

2. Automotive industry: Sheet silver coated copper powder is used to prepare high-temperature lubricating materials, such as engine crankshaft bearings, gear transmissions, etc., playing an important role in the automotive industry.

   
   

3. Aerospace: Sheet silver coated copper powder can be used to prepare high-temperature ceramic materials, packaging materials, etc., and has a wide range of applications in the aerospace field.

   
   

4. Medical and health: Sheet silver coated copper powder can be used to prepare antibacterial materials, such as medical dressings, masks, etc., and has a wide range of applications in the medical and health field.

   
   

5. Other fields: Sheet silver coated copper powder can also be used in the preparation of lithium-ion batteries, solar cells, and other fields, as well as the preparation of some special materials.

2、 The use of flake silver foil copper powder may encounter the following problems:

1. Agglomeration: Due to the electrostatic attraction between the particles of silver coated copper powder, it is easy to form clumps, which affects the dispersion and properties of the material.

   
   

2. Oxidation: Silver is a metal with weak oxidation properties, but it is easily oxidized and loses its conductivity when exposed to air for a long time.

   
   

3. Precipitation: Flake silver coated copper powder contains relatively large particles, which are prone to precipitation. In the preparation processConductive pasteIt is necessary to stir or add dispersants to maintain the dispersed state.

   
   

4. Uneven particle size distribution: The uneven particle size distribution of flake silver coated copper powder may affect the performance and stability of the material.

   
   

To avoid the above problems, it can be solved by selecting appropriate production processes, adding surface modifiers, and other methods.

3、 When purchasing silver foil copper powder, the following precautions should be taken:

1. Confirm whether the product specifications and usage meet the requirements.

   
   

2. Choose legitimate suppliers or manufacturers to ensure reliable product quality and possess relevant production qualifications and certifications.

   
   

3. It is necessary to understand the ingredients, content, and packaging information of the product in order to use and store it correctly.

   
   

4. Understand market prices before purchasing to avoid being scammed by high prices.

   
   

5. Pay attention to storage conditions and avoid being affected by moisture, oxidation, and other factors.
