产品代码 : EM-Re-5N-Cu

Rhenium is a silver-gray heavy metal, which belongs to the third-row transition metal in group 7 of the periodic table. It is one of the rarest elements in the Earth’s crust, with an average content estimated at one part in a billion. Rhenium is also one of the elements with the highest melting and boiling points.

产品代码 : EM-Pr-5N-Cu

Praseodymium is a metal element with an atomic number of 59, which is a rare earth metal. The corrosion resistance of praseodymium in the air is stronger than that of lanthanum, cerium, neodymium and europium. One of the uses of praseodymium is for the catalytic cracking of petroleum.

产品代码 : EM-Pt-5N-Cu

Platinum is one of nine precious metals on the periodic table. It has a melting point of 1,772°C, a density of 21.4 g/cc, and vapor pressure of 10-4 Torr at 1,747°C. It is a radiant, silvery-white metal that bears a striking resemblance to palladium. It is dense, malleable, ductile, and corrosion resistant in the air.

产品代码 : EM-Pd-5N-Cu

Palladium is a silvery-white precious metal that bears a strong resemblance to platinum. It has a melting point of 1,554°C, a density of 12.038 g/cc, and vapor pressure of 10-4 Torr at 1,192°C. It belongs to the platinum group of metals on the periodic table. It has the lowest melting point of the elements of this group and is the least dense.

产品代码 : EM-Nb-5N-Cu

Niobium, formerly columbium, is a chemical element with the symbol Nb (formerly Cb) and atomic number 41. It is a soft, grey, ductile transition metal, often found in the minerals pyrochlore and columbite.

产品代码 : EM-Ni-5N-Cu

Nickel is a hard, lustrous, silvery-white metal. It has a density of 8.91 g/cc, a melting point of 1,453°C, and a 10-4 Torr vapor pressure at 1,262°C. Its key characteristics are malleability, ductility, and ferromagnetism and its polished surface resists tarnishing when exposed to air.
