Beryllium Copper Plates are made from beryllium copper alloy materials and boast properties like high strength, superior capability of both electrical conduction and thermal conduction, and good fatigue resistance. UNS C17200 is one of the widely used grades, offering similar strength as steel but with the conductivity of copper alloys. They are produced through ASTM B194 verification tests, and they can be offered in different types based on customer specifications and their needs.

Sachin Steel Centre provides Beryllium Copper Plates in various grades, dimensions, and tempers to serve the needs of various industrial industries, such as aerospace, automotive, electrical, and oil & gas industries.

Applications of Beryllium Copper Plates

Beryllium copper plates are selected for applications requiring high strength, conductivity, fatigue resistance, and dimensional stability.

Aerospace: Used in structural and load-bearing components where strength, stability, and resistance to stress relaxation are required.
Automotive: Suitable for sensors, connectors, and spring contacts requiring durability, conductivity, and vibration resistance.
Electrical & Electronics: Used in switches, relays, connectors, and shielding components requiring reliable electrical performance and fatigue resistance.
Oil & Gas: BeCu plates are used for drilling and downhole tools where non-sparking and corrosion-resistant properties are important.
Defence: Applied in navigational instruments, specialised components, and equipment exposed to demanding mechanical and environmental conditions.

Frequently Asked Questions

What are beryllium copper plates?

Beryllium copper plates are copper alloy plates containing beryllium, offering high strength, conductivity, fatigue resistance, and good dimensional stability.

What is the main grade of beryllium copper plate?

UNS C17200 is a widely used beryllium copper plate grade, known for high strength, conductivity, and suitability for age-hardening applications.

What standard covers beryllium copper plates?

ASTM B194 covers beryllium copper plates, sheets, strips, and rolled bars, including copper-beryllium alloys such as C17000 and C17200.

What are beryllium copper plates used for?

Beryllium Copper Plates are used in aerospace, automotive, electrical, electronics, oil and gas, defence, and applications requiring strength and conductivity.

Are beryllium copper plates electrically conductive?

Yes. Beryllium Copper Plates retain useful electrical conductivity while providing substantially higher strength than many conventional copper alloys.

Can beryllium copper plates be age-hardened?

Yes. C17200 Beryllium Copper Plates can be precipitation-hardened or age-hardened to achieve high tensile strength and hardness.

What are the advantages of beryllium copper plates?

Beryllium copper plates offer high strength, good electrical conductivity, fatigue resistance, corrosion resistance, dimensional stability, and excellent spring properties.

What is the difference between C17000 and C17200 Beryllium Copper?

C17000 contains less beryllium than C17200. C17200 generally provides higher strength and is widely selected for demanding age-hardening applications.
