Beryllium. Beryllium is six times stronger than steel and more than 30% lighter than aluminum.
Why is beryllium used in electronics?
Copper berylliumCopper berylliumBeryllium copper (BeCu), also known as copper beryllium (CuBe), beryllium bronze and spring copper, is a copper alloy with 0.5–3% beryllium and sometimes other elements. Beryllium copper combines high strength with non-magnetic and non-sparking qualities. It has excellent metalworking, forming and machining properties.https://en.wikipedia.org › wiki › Beryllium_copperBeryllium copper - Wikipedia alloys provide “spring memory” that ensures continuous, fatigue-free electrical connections through constant use, openings and closings, vibrations and accidental drops.
Why is beryllium so expensive?
Beryllium is primarily produced using bertrandite and beryl ores. ... High-purity beryllium is expensive owing to its properties such as high stiffness, lightweight, and high elastic modulus.
