Beryllium Copper With High Conductivity

Product Description

Beryllium copper alloy is a composite material created by blending beryllium with copper in specific proportions. Thanks to beryllium's outstanding conductive properties, this combination results in an alloy with exceptional electrical conductivity. Typically, beryllium copper alloys can achieve conductivity levels exceeding 90% of pure copper, and in some cases even higher, making them highly sought after in the electronics sector.

 

The superior conductivity of beryllium copper alloys has led to their widespread adoption in the electronics industry. These alloys are primarily utilized in the production of electrical appliances, electronic components, and communication devices. Additionally, beryllium copper alloys offer notable strength and corrosion resistance, enabling them to perform reliably under challenging conditions such as high temperatures and pressures.

 

Among the various grades, C17200, C17000, C17510, and C17500 beryllium copper alloys are particularly favored in electronic applications due to their high conductivity. These materials are commonly processed into forms like strips, foils, and wires to meet the diverse needs of the industry.

Properties

• High Electrical Conductivity: Beryllium copper alloys, particularly those with lower beryllium content (e.g., C17200), exhibit high electrical conductivity, often around 22-60% IACS (International Annealed Copper Standard). This makes them suitable for electrical and electronic applications.
• High Thermal Conductivity: The alloy also has good thermal conductivity, which is beneficial in applications requiring heat dissipation.
• Strength and Hardness: Beryllium copper can be heat-treated to achieve high strength and hardness, making it suitable for demanding mechanical applications.
• Corrosion Resistance: The alloy has excellent corrosion resistance, particularly in marine environments, due to the formation of a protective oxide layer.
• Non-Sparking and Non-Magnetic: Beryllium copper is non-sparking and non-magnetic, making it ideal for use in explosive environments and in applications where magnetic interference must be avoided.

 

Heat Treatment

Beryllium copper can be heat-treated to enhance its mechanical properties. The typical heat treatment process involves solution annealing followed by age hardening (precipitation hardening). This process increases the strength and hardness of the alloy while maintaining good conductivity.

 

Safety Considerations

Beryllium Dust and Fumes: Beryllium is a toxic material, and inhaling beryllium dust or fumes can cause chronic beryllium disease (CBD). Proper safety measures, such as using protective equipment and ensuring adequate ventilation, are essential when machining or processing beryllium copper.
