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
Group 6 element 1924. For about a century after its isolation, molybdenum had no industrial use, owing to its relative scarcity, difficulty extracting the pure metal, and the immaturity of the metallurgical subfield. Early molybdenum steel alloys showed great promise in their increased hardness, but efforts were hampered by inconsistent results and a tendency toward brittleness and recrystallization. In 1906, William D. Coolidge filed a patent for rendering molybdenum ductile, leading to its use as a heating element for high-temperature furnaces and as a support for tungsten-filament light bulbs; oxide formation and degradation require that moly be physically sealed or held in an
