Tungsten (or tungsten) is a shiny, silvery-white metal. Tungsten was widely used for the filaments of old-style incandescent bulbs, but these have been phased out in many countries. This is because they are not very energy efficient and produce more heat than light. Tungsten (or tungsten) has the highest melting point of all metals and is alloyed with other metals to strengthen them. Tungsten and its alloys are used in many high temperature applications such as arc welding electrodes and heating elements in high temperature furnaces.

Tungsten carbide is extremely hard and essential to the metalworking, mining and petroleum industries. It is made by mixing tungsten powder and carbon powder and heating it to 2200 degrees.
Calcium and magnesium tungstates are widely used in fluorescent lighting.
Tungsten is the heaviest metal known to have a biological role. Some bacteria use tungsten in an enzyme to reduce carboxylic acids to aldehydes.
The main wolfram-bearing ores are scheelite and wolframite. The metal is obtained commercially by reduction of tungsten oxide with hydrogen or carbon.
In the tests and analyzes carried out in our organization, which has a wide range of technological equipment, trained and experienced staff and applies the most modern methods, national and international standards and legal regulations in force are complied with. Among the numerous tests carried out in this context, there are tungsten (W) testing services within the framework of elemental analysis.
