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
Brass type and concentration of pathogens and the medium they are in, brass kills these microorganisms within a few minutes to hours of contact. A large number of independent studies confirm this antimicrobial effect, even against antibiotic-resistant bacteria such as MRSA and VRSA. The mechanisms of antimicrobial action by copper and its alloys, including brass, are a subject of intense and ongoing investigation. Brass is susceptible to stress corrosion cracking, especially from ammonia or substances containing or releasing ammonia. The problem is sometimes known as season cracking after it was first discovered in brass cartridges used for rifle ammunition during the
