Cymbal alloys was previously described by their sales literature as containing tin rather than zinc. There is a minority view that the word "bronze" should be reserved for two-phase alloys, which may be their usage here. Unlike cymbals, some gongs are made from several different metals fused together. Many different metals have been used. Parts of some traditional gongs, notably the bosses of some "nipple" gongs, are made from iron based alloys. A few independent cymbal makers have also used stainless steel and titanium to produce cymbals and gongs. How Alloying Elements Affect the Properties of Copper Alloys Cymbal alloys Cymbals are
Period 2 element alloys with aluminium, cadmium, copper and manganese are used to make high performance parts for aircraft, most notably the external tank of the Space Shuttle. Beryllium (Be) is the chemical element with atomic number 4, occurring in the form of Be. At standard temperature and pressure, beryllium is a strong, steel-grey, light-weight, brittle, bivalent alkali earth metal, with a density of 1.85 g·cm. It also has one of the highest melting points of all the light metals. Beryllium's most common isotope is Be, which contains 4 protons and 5 neutrons. It makes up almost 100% of all naturally occurring beryllium
