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
Period 4 element can also be found in semiconductors. Germanium (Ge) is an element in period 4, between gallium and arsenic. Germanium, like silicon above it, is an important semiconductor and is commonly used in diodes and transistors, often in combination with arsenic. Germanium is fairly rare on Earth, leading to its comparatively late discovery. Germanium, in compounds, can sometimes irritate the eyes, skin, or lungs. Arsenic (As) is an element in period 4, between germanium and selenium. Arsenic, as mentioned above, is often used in semiconductors in alloys with germanium. Arsenic, in pure form and some alloys, is incredibly poisonous to all
