Beryllium Copper

The alloy contains approximately 2% beryllium, giving it superior corrosion resistance compared to other copper alloys. This makes it an ideal choice for applications where exposure to harsh chemicals may be expected. Additionally, beryllium copper 172 is resistant to hydrogen embrittlement, which can cause failure in other materials when exposed to hydrogen at high pressures and temperatures.

‌‌Beryllium copper material has the characteristics of high strength, high elasticity, high hardness and high wear resistance. ‌

Beryllium copper, also known as beryllium bronze or beryllium copper alloy, is a Wuxi bronze with beryllium as the main alloying element. It contains 1.7 to 2.5% beryllium and a small amount of nickel, chromium, titanium and other elements. After quenching and aging treatment, its strength limit can reach 1250 to 1500MPa, which is close to the level of medium-strength steel. In the quenched state, beryllium copper has very good plasticity and can be processed into various semi-finished products. Beryllium copper has high hardness, elastic limit, fatigue limit and wear resistance, as well as good corrosion resistance, thermal conductivity and electrical conductivity. When impacted, beryllium copper does not produce sparks, which makes it widely used in the manufacture of important elastic components, wear-resistant parts and explosion-proof tools. Commonly used beryllium copper grades include QBe2, QBe2.5, QBe1.7 and QBe1.9.

In addition, beryllium copper also has the following characteristics:

‌Spark-free property‌: It will not produce friction sparks when colliding with other metals, and is suitable for flammable and explosive environments such as oil drilling platforms and coal mines.
‌Wear resistance‌: Even under overload conditions and continuous vibration, the friction and surface damage generated when in contact with other metal parts are very small.
‌Non-magnetic‌: As a non-ferrous metal, beryllium copper is non-magnetic, and magnetic fields will not affect its normal function.
‌Performance at extreme temperatures‌: Under extreme temperatures, the tensile strength and toughness of beryllium copper can be maintained, and it is suitable for low temperature conditions and high temperature environments.
‌Corrosion resistance‌: It will not corrode in harsh environments, is resistant to biological contamination, and is not easy to lose its luster.
‌Good machinability‌: Beryllium copper is relatively easy to process and is suitable for various processing and forming processes.

In summary, beryllium copper has a wide range of use value in industrial applications due to its unique physical and chemical properties.
