Samarium (Sm) Foil

Product Code : RE-Sm-5N-SF

Samarium is a silvery-white metal and a member of the lanthanoid group of the Periodic Table and the 40th most abundant element within the Earth’s crust. Samarium Metal tarnishes in the air, and it is relatively hard. Its hardness and density are similar to zinc. Samarium Metal has primarily been utilized in the production of Samarium-Cobalt (Sm2Co17) permanent magnets with one of the highest known demagnetization resistance.

ATT specializes in producing Samarium High Purity Foil and sheets in many thicknesses and sizes for numerous industrial uses.

Applications of Samarium (Sm) Metal

Samarium Metal has primarily been utilized in the production of Samarium-Cobalt (Sm2Co17) permanent magnets with one of the highest resistances to demagnetization known. High purity Samarium Metal is also used in making specialty alloy and sputtering targets. Samarium-149 has a high cross-section for neutron capture (41,000 barns) and is therefore used in the control rods of nuclear reactors. Samarium Metal can be further processed to various shapes of sheets, wires, foils, slabs, rods, discs, and powder.

Samarium is used as a catalyst in certain organic reactions: the samarium iodide (SmI2) is used by organic research chemists to make synthetic versions of natural products. The oxide, samaria, is used for making special infrared adsorbing glass and cores of carbon arc-lamp electrodes and as a catalyst for the dehydration and dehydrogenation of ethanol. Its compound with cobalt (SmCo5) is used in making a new permanent magnet material.

Samarium Metal Sm is applied in petroleum and environment protection catalysts, mischmetal, polishing powders and Rare Earth fertilizers. 


Packing of Samarium (Sm) Foil

Standard Packing:

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities.

Aluminum Samarium Alloy
Aluminum Samarium Alloy

Aluminium alloy is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin, nickel and zinc. There are two principal classifications, namely casting alloys and wrought alloys, both of which are further subdivided into the categories heat-treatable and non-heat-treatable

Magnesium Samarium Alloy
Magnesium Samarium Alloy

Magnesium alloys are mixtures of magnesium with other metals, often aluminium, zinc, manganese, silicon, copper, rare earths and zirconium. Magnesium alloys have a hexagonal lattice structure, which affects the fundamental properties of these alloys. Plastic deformation of the hexagonal lattice is more complicated than in cubic latticed metals.
