Copper Alloy 25, also known as C17200 or BeCu 25, is a special type of copper alloy that contains beryllium. This alloy is renowned for its unique combination of high mechanical strength, excellent hardness, and good electrical and thermal conductivity. These characteristics make Copper Alloy 25 an ideal choice for various industrial applications requiring high-performance materials.

Key characteristics of Copper Alloy 25:

- Chemical Composition:
- C17200 primarily consists of copper (Cu) with about 1.8-2% beryllium (Be), and a small amount of cobalt (Co) or nickel (Ni) to enhance strength and mechanical properties.

- Physical Properties:
- High Strength and Hardness: Copper Alloy 25 offers high tensile strength and exceptional hardness, making it resistant to deformation under heavy loads.
- Good Electrical and Thermal Conductivity: Although not as high as pure copper, this alloy still maintains good electrical and thermal conductivity.
- Corrosion Resistance: The alloy provides good resistance to corrosion, even in harsh environments.

- Applications:
- Electronics and Telecommunications: Used in electrical connectors, contacts, springs, and components that require high strength and good conductivity.
- Aerospace and Defense: Employed in aircraft components, military equipment, and applications that demand high load-bearing and heat resistance.
- Mold Making: Used in the manufacture of plastic injection molds and tools requiring high durability and good wear resistance.

- Shape and Size:
- Copper Alloy 25 is typically available in forms such as rods, plates, tubes, and other product forms depending on specific application requirements.

Manufacturing and Processing:
- C17200 is produced through casting and hot working processes. It is easily machinable and weldable, but care must be taken due to the health risks associated with beryllium inhalation.
