Kencotube is a pioneer in exporting, manufacturing & trading Tantalum Sheets, which is a chemical element with symbol Ta and atomic number 73. Tantalum Plates is a rare, hard, blue-grey, lustrous transition metal that is highly corrosion-resistant, where it is a part of the refractory metals group that are widely used as minor components in alloys. Tantalum Coils is ductile, very hard, dark, dense, easily made-up, and extremely conductive of electricity and heat, which occurs in two crystalline stages - alpha & beta. Tantalum Alloy Sheets is renowned for its resistance to corrosion by acids; in fact, at temperatures below 150 Degree C and is almost completely immune to attack by the normally aggressive aqua region. Tantalum Alloy Plates can be softened by means of acidic solutions or hydrofluoric acid comprising the sulfur trioxide and fluoride ion, in addition to with a solution of potassium hydroxide.
Tantalum Alloy Coils 'high melting point of 3017 Degree C (boiling point 5458 Degree C) is exceeded among the elements only by tungsten, rhenium and osmium for metals, and carbon. Ta Sheets is also used in chemical process equipment, nuclear reactors and certain parts of missiles, which also helps in maintaining high vacuum, by capturing oxygen and nitrogen in the form of nitrides and oxides. Ta Plates is also used in forming vacuum furnace parts, in thermowells, fasteners and valve bodies. Ta Plates is as well used as an orthopaedic implant material, where in addition it forms a part of glasses with high refractive indices.
