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
High entropy alloys greater than or equal to 1.1 to promote solid solution development. The atomic radii of the components must also be similar in order to form a solid solution. Zhang et al. proposed a parameter δ representing the difference in atomic radii: where r is the atomic radius of element i and formula_8. Formation of a solid solution phase requires a δ≤6.6%, but some alloys with 4%<δ≤6.6% do form intermetallics. For those alloys that do form solid solutions, an additional empirical parameter has been proposed to predict the crystal structure that will form. If the average valence electron concentration (VEC) of
