Cymbal alloys are typically very poor in tone, some even being disks of untreated metal and unplayable despite the reputable brand name they may bear. The brass for cymbals is about 38% zinc in copper, which is very easily worked, readily available as sheet metal, and easily the cheapest metal stock normally used for cymbals. The tone of brass cymbals tends to be warm but dull compared to any sort of tin bronze, and very few drummers exploit it. Examples of brass cymbals include: Harpy B, Meinl Marathon M38, Meinl Meteor, Meinl HCS, Orion Twister, Paiste 101, Paiste 302 and some Exotic
Copper alloys in aquaculture susceptible to chloride stress corrosion. Copper–silicon has a long history of use as screws, nuts, bolts, washers, pins, lag bolts, and staples in wooden sailing vessels in marine environments. The alloys are often composed of copper, silicon, and manganese. The inclusion of silicon strengthens the metal. As with the copper–nickel alloys, corrosion resistance of copper–silicon is due to protective films that form on the surface over a period of time. General corrosion rates of 0.025–0.050mm have been observed in quiet waters. This rate decreases towards the lower end of the range over long-term exposures (e.g., 400–600 days). There is generally
