Cymbal alloys Percussion, Pearl, Royal, Twister Series by Orion, Solar and Sbr by Sabian, Soultone Intro, UFIP M8, Planet Z by Zildjian, nearly all zils of all makes. Nickel silver as used in cymbal making is an alloy of copper and nickel, and an alloy with about 12% nickel is used for some beginners' cymbals. 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. Some maintain that the term "nickel silver" should only be used for alloys containing an appreciable content of zinc, and would call
Post-transition metal (MH 2.25) and brittle semi-metallic element. It is commonly regarded as a metalloid, or by some authors either as a metal or a non-metal. Tellurium has a polyatomic (CN 2) hexagonal crystalline structure. It is a semiconductor with a band gap of 0.32 to 0.38 eV. Tellurium forms covalent bonds with most other elements, noting it has an extensive organometallic chemistry and that many tellurides can be regarded as metallic alloys. The common oxide of tellurium (TeO) is amphoteric. Tellurium forms a series of anionic tellurites and tellurates such as NaTeO, NaTeO, and RbTeO (the last containing tetrahedral and trigonal
