2019 has been declared by UNESCO as the Year of the Periodic Table. To celebrate, we are releasing a series of blogs about our favourite elements and their importance to the chemical industry. Today’s blog focuses on Beryllium.
Beryllium copper alloys account for a huge percentage of the beryllium used in the United States. As these alloys are good conductors of electricity and heat, they are used in making connectors, switches and other electrical devices for use in many sectors including aerospace, automobile, computer, defense and medical.
Beryllium metal is very light and stiff and maintains its shape in both high and low temperatures. This makes it the ideal material for use as mirrors of the Spitzer Space Telescope and the James Webb Space Telescope (JWST), due to be launched in the next few years. The key mirror of the JWST comprises 18 hexagonal segments- each must maintain its shape even at - 400 degrees Fahrenheit.
Automobile and Aircraft
Additionally, Beryllium alloy connectors are used in the electrical systems of automobiles, as they are reliable and improve vehicle fuel efficiency.
In commercial aircraft, the strength of beryllium copper provides many advantages, as it can handle wear forces and exposure to corrosive atmospheres and temperatures. Beryllium copper also allows bearings to be made lighter and smaller, which also improves fuel efficiency.
Beryllium copper’s strength and stability makes it ideal for medical technologies and x-ray equipment.
As imaging technology progresses, beryllium copper will continue to play an important role in x-ray tube windows.
