产品代码 : EM-Zn-5N-Cu

Zinc is located in the 4th period, group IIB in the periodic table of chemical elements. It is a light grey transition metal and the fourth most “common” metal. In modern industry, zinc is irreplaceable in battery manufacturing and is a very important metal.

产品代码 : EM-Y-5N-Cu

Yttrium is a gray-black metal with the chemical symbol Y. It is the first rare earth metal element to be discovered. Yttrium is ductile, can react with hot water, and is easily soluble in dilute acid. It can be used to make special glasses and alloys.

产品代码 : EM-Yb-5N-Cu

Ytterbium is a ductile silver-white metal. The content of ytterbium in the crust is 0.000266%, mainly in xenotime and black rare gold, and there are 7 kinds of natural isotopes.

产品代码 : EM-V-5N-Cu

Vanadium is a silver-gray metal with common valences of +5, +4, +3, +2. Vanadium has a high melting point and is a refractory metal. Vanadium is ductile, hard and non-magnetic. It has the ability to resist hydrochloric acid and sulfuric acid, and has better resistance to gas, salt and water corrosion than most stainless steels.

产品代码 : EM-W-5N-Cu

Tungsten is a rare metal found naturally on Earth almost exclusively combined with other elements in chemical compounds rather than alone. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include wolframite and scheelite. Tungsten evaporation materials can alloy with some materials.
