Welcome to Sovereign International Metals and Alloys, Inc. (SIMA) began operations in 1984, trading nickel and nickel-cobalt based alloys. Today, SIMA handles:


Chrome, Cobalt, Gallium, Hafnium, Molybdenum, Nickel, Niobium, Rhenium, Ruthenium, Tantalum, Tungsten, and a wide variety of alloys containing the above elements both in prime and refinery grades. Including Densalloy, Kovar, W carbide, etc. We deal with alloys scraps like IN718, IN625, etc. We both buy and sell all of these. In addition, we purchase grindings, turning etc. All of these products are produced to melt into Ni/Co superalloys in metal forms. We offer both long term supply as well as spot.


SIMA has evolved from a strict recycler of metals to an international trader in "minor metals" with warehouses in Germany, Great Britain, Holland, and the United States. SIMA products are used in chemical plants, catalysts, diesel engines, Aerospace turbine, solar panels, and electronics such as LED lighting, capacitors, and plasma TVs.


SIMA’s customer base includes but is not limited to the large investments casting companies, and large mills. We also work closely and are qualified with some of the large Aero engine OEM’s.
