2.Standards:

China: GB/T 4423-1992 (TAg0.1)

USA: ASTM C10400

Germany: DIN CuAg0.1

Japan: JIS C10400

International: ISO CuAg0.1

3.Performance Characteristics:

（1）Physical Properties:

• CuAg0.1 has a metallic copper appearance, with a slight silvery sheen.

• Its density is approximately 8.9 g/cm³, falling between that of pure copper and pure silver.

• The melting point is lower than that of pure copper and pure silver due to the atomic interactions between copper and silver, disrupting the pure metal crystal structure and lowering the melting point.

（2）Chemical Properties:

CuAg0.1 exhibits good corrosion resistance and remains stable under typical atmospheric conditions.

（3）Mechanical Properties:

• Tensile strength: ≥275 MPa

• Elongation (δ10%): ≥5

• Elongation (δ5%): ≥10

• Compared to pure copper, CuAg0.1 has higher strength and hardness, improved wear resistance, and better fatigue resistance.

（4）Electrical Properties:

Copper is already an excellent conductor of electricity, and the addition of silver further enhances the conductivity of CuAg0.1. This alloy has an extremely low resistivity, enabling highly efficient electrical current transmission, making it highly advantageous in electrical and electronic applications.

4.Preparation Methods:

（1）Melting Method:

High-purity copper and silver are proportioned and placed in a furnace, heated above 1083°C (the melting point of copper) to melt the metals. The mixture is stirred thoroughly, and then solidified at a controlled cooling rate. During the melting process, precise control over temperature, time, and raw material proportions is essential to ensure the alloy's composition and properties meet the required standards.

（2）Powder Metallurgy:

Copper and silver powders are mixed thoroughly in the correct proportion and pressed into the desired shape under pressure. The pressed compacts are then sintered in a high-temperature furnace. During sintering, diffusion and fusion occur between the powder particles, forming a dense alloy material. This method allows precise control over the alloy's composition and microstructure, ensuring the creation of high-performance CuAg0.1.

（3）Heat Treatment Specifications:

• Hot working temperature: 900-1050°C

• Annealing temperature: 500-700°C

• Recrystallization temperature for cold-worked copper: 200-300°C

• Proper heat treatment can further optimize the microstructure and properties of CuAg0.1, making it suitable for a variety of application requirements.

5.Performance Advantages:

• High Electrical and Thermal Conductivity:

With a conductivity of 97%-99% IACS (International Annealed Copper Standard), CuAg0.1 is suitable for applications requiring high electrical conductivity.

• High Temperature Softening Resistance:

CuAg0.1 is more resistant to softening under high temperatures compared to pure copper, maintaining mechanical strength over extended periods.

• Enhanced Mechanical Strength:

The addition of silver increases hardness and tensile strength, improving wear resistance and fatigue resistance.
