WebAug 7, 2013 · Tantalum is a chemical element with Ta as its symbol. It belongs to group 5, periodic number 6 of the periodic table. Its atomic number is 73. Tantalum is a silvery metal that is soft in its pure form. It is a strong and ductile metal and at temperatures below 150°C (302°F), this metal is quite immune to chemical attack. WebTungsten-based metal matrix composites (W-MMC) specifically combine the special properties of tungsten with the properties of other metals. Tungsten has the highest melting point of all metals and therefore also the highest application temperatures. Its very low coefficient of thermal expansion and high dimensional stability are also unique.
