Cymbal alloys are typically very poor in tone, some even being disks of untreated metal and unplayable despite the reputable brand name they may bear. The brass for cymbals is about 38% zinc in copper, which is very easily worked, readily available as sheet metal, and easily the cheapest metal stock normally used for cymbals. The tone of brass cymbals tends to be warm but dull compared to any sort of tin bronze, and very few drummers exploit it. Examples of brass cymbals include: Harpy B, Meinl Marathon M38, Meinl Meteor, Meinl HCS, Orion Twister, Paiste 101, Paiste 302 and some Exotic
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
