    Copper and Copper Alloys Casting Problems

    Group II alloys

    Group II alloys are those that have an intermediate freezing range, that is, a freezing range of 50 to 110oC between the liquidus and the solidus. Group II alloys are: beryllium copper (C81400, C82000, C82200, C82400, C82500, C82600, C82800), silicon brass (C87500), silicon bronze (C87300, C87600, C87610, C87800), copper-nickel (C96200, C96400).

    Beryllium Coppers. These alloys are very toxic and dangerous if beryllium fumes are not captured and exhausted by proper ventilating equipment. They should be melted quickly under a slightly oxidizing atmosphere to minimize beryllium losses. They can be melted and poured successfully at relatively low temperatures. They are very fluid and pour well.

    Silicon Bronzes and Brasses. The alloys known as silicon bronzes, UNS alloys C87300, C87600, and 87610, are relatively easy to melt and should be poured at the proper pouring temperatures. If overheated, they can pick up hydrogen. While degassing is seldom required, if necessary, one of the proprietary degasifiers used with aluminum bronze can be successfully used.

    Normally no cover fluxes are used here. The silicon brasses (UNS alloys C87500 and C87800) have excellent fluidity and can be poured slightly above their freezing range. Nothing is gained by excessive heating, and in some cases, heats can be gassed if this occurs. Here again, no cover fluxes are required.

    Copper-Nickel Alloys. These alloys (90Cu-10Ni, UNS C96200 and 70Cu-30Ni, UNS C96400) must be melted carefully because the presence of nickel in high percentages raises not only the melting point but also the susceptibility to hydrogen pickup. In virtually all foundries, these alloys are melted in coreless electric induction furnaces, because the melting rate is much faster than it is with a fuel-fired furnace.

    When ingot is melted in this manner, the metal should be quickly heated to a temperature slightly above the pouring temperature and deoxidized either by the use of one of the proprietary degasifiers used w
