[citation needed] In 1989 Paiste released professional cymbal series composed of sheet metal bronze with about 15% tin.
Though the manufacturing requires the metal to be rolled hot at certain stages, it is not tempered like traditional B20 cymbals but annealed.
From the mid 20th century there were attempts to make top-quality cymbals from malleable bronze, originally for reasons of economy.
As the Paiste patent referred to above says: Less than three decades ago experiments were carried out for economical considerations with a commercial common bronze sheet or plating containing 8% tin by weight.
In particular, top-line malleable bronze cymbals proved exceptionally suitable for the louder music then developing.
Examples of malleable bronze cymbals include: Harpy H, Meinl One of a Kind, Meinl Custom and Amun, Meinl Lightning and Raker, Meinl Classics and some Generation X, Meinl Trooper and Cadet, Orion Solo Pro and Solo Pro Master, Orion Viziuss, Paiste 2002 and Giant Beat, Paiste 802 and Alpha, Paiste 502 and some Exotic Percussion, Pearl Pro, Meinl MCS, Sabian B8 and B8 Pro, Sabian Pro, Sabian Pro Sonix, Sabian APX, Sabian B8X, Soultone Custom Brilliant, Soultone Extreme, Soultone Natural, Soultone Vintage, Soultone Vintage OldSchool 1964, Soultone Gospel, UFIP Tiger, UFIP Supernova, Zildjian I Series, ZBT, ZXT, ZHT, and the sonic "XXX" series by Krash Cymbalz, a B10 alloy line for the heavy-handed, aggressive drummer.
Many of the "show" cymbals provided by many drum kit manufacturers for use in shop window displays are also made from brass.
These are typically very poor in tone, some even being disks of untreated metal and unplayable despite the reputable brand name they may bear.
The tone of brass cymbals tends to be warm but dull compared to any sort of tin bronze, and very few drummers exploit it.
A very few specialised high-quality cymbals are also made from nickel silver, as are some top-quality gongs tending to the more modern and exotic sounds.
Nickel silver is malleable and available as commercial sheet metal, and gives a bright tone but without the shimmer and sensitivity of tin bronzes.
