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
Microstructurally stable nanocrystalline alloys Microstructurally stable nanocrystalline alloys Microstructurally stable nanocrystalline alloys are alloys that are designed to resist microstructural coarsening under various thermo-mechanical loading conditions. Many applications of metal materials require that they can maintain their structure and strength despite very high temperatures. Efforts to prevent deformations from long term stress, referred to as creep, consist of manipulating alloys to reduce coarsening and migration of individual grains within the metal. The small size of individual metal grains provides high interfacial surface energy which is what prompts coarsening, the increase in grain size, and eventually metallic softening. Nanocrystalline creep is considered to follow the
