Sand casting greater cost. With a completed mold at the appropriate moisture content, the box containing the sand mold is then positioned for filling with molten metal—typically iron, steel, bronze, brass, aluminium, magnesium alloys, or various pot metal alloys, which often include lead, tin, and zinc. After being filled with liquid metal the box is set aside until the metal is sufficiently cool to be strong. The sand is then removed, revealing a rough casting that, in the case of iron or steel, may still be glowing red. In the case of metals that are significantly heavier than the casting sand, such
Cymbal alloys Cymbal alloys Cymbals are made from four main alloys, all of them copper-based. These are: bell bronze, malleable bronze, brass, and nickel silver. Bell bronze, also known as "bell metal", is the traditional alloy used for fine cymbals, many gongs, and, as the name suggests, bells. It is normally stated to be one part tin to four parts copper, that is 20% tin, and this is still the most common formula, but there has always been some variation. Larger and smaller bells are cast with differing amounts of tin, and some bell, gong, and cymbal makers use small but significant
