Cymbal alloys was previously described by their sales literature as containing tin rather than zinc. There is a minority view that the word "bronze" should be reserved for two-phase alloys, which may be their usage here. Unlike cymbals, some gongs are made from several different metals fused together. Many different metals have been used. Parts of some traditional gongs, notably the bosses of some "nipple" gongs, are made from iron based alloys. A few independent cymbal makers have also used stainless steel and titanium to produce cymbals and gongs. How Alloying Elements Affect the Properties of Copper Alloys Cymbal alloys Cymbals are
Native metal more reactive than gold. Natural alloys of the platinum group metals include: native osmium (Os,Ir,Ru), rutheniridosmine (Ir,Os,Ru), ruthenium (Ru,Ir), palladium (Pd,Pt), platinum Pt, and rhodium (Rh,Pt). In addition gold, copper, iron, mercury, tin and lead may occur in alloys of this group. As with gold, salts and other compounds of the platinum group metals are rare; native platinum and related metals and alloys are the predominant minerals bearing these metals. These metals occur associated with ultramafic intrusions and placer deposits derived from those intrusions. Native copper has been historically mined as an early source of the metal. The term Old
