Beryllium is alloyed with copper (2% beryllium, 98% copper) to form a wear resistant material, known as beryllium bronze, used in gyroscopes and other devices where wear resistance is important.ther beryllium alloys are used in the windshield, brake disks and other structural components of the space shuttle. Beryllium oxide (BeO), a compound of beryllium, is used in the nuclear industry and in ceramics.
The full answer is that, like all human beings, babies do need to take in water in order to survive. But they don't actually need to drink waterin fact, pediatricians advise against giving your baby plain or distilled water until he or she is six months old.
