26. Tantalum (Ta)
Tantalum (Ta) and the white metal can be formed through cold working process. Process of heat can increase the hardness numbers drastically. Tantalum (Ta) has a melting point of 32070C and used in Cementite Carbide tooling and as an additional element to metal alloy non-Ferro.
27. Tellurium (Te)
Tellurium (Te) has a melting point of 4520C slightly Lead will be added to increase hardness, and if added to Copper will provide free-cutting properties.
28. Thorium (Th)
Thorium (Th) is very soft like lead (Lead) and can be melted at a temperature of 18270C. Thorium (Th) is used as an alloying element in the manufacture of tungsten wire filament and Magnesium is also used in alloys to produce Creep resistance properties.
29. Tungten, tungsten (W)
Tungten, tungsten (W) has a melting point of 34100C gray, very hard and brittle at room temperature, but tenacious and clay at high temperatures. The basic ingredients of Tungten, tungsten (W) Oxide minerals and this is obtained through the reduction process. Tungten, tungsten (W) filament is used as materials, to Kwat radio and lights and is also used as an alloying element in the cutting tool (Tool Steel) ie as a High Speed Steel (HSS) or high speed steel, steel and formed through a process Magnet sintering for tooling materials.
30. Vanadium (V)
Vanadium (V) will melt at temperatures above 19000C, the white metal is very hard, if added as an alloying element in steel will increase the elasticity of the steel.
31. Beryllium (Be)
Beryllium (Be) metal gray has properties very hard with a melting point of 12850C but lighter than aluminum. Beryllium has a low in the damping properties of neutrons in the direction of cutting so as not to react to the various forms and degrees of neutrons in its path. Beryllium (Be) is a metal that has the thermal properties of the conductor as well as a good and stable voltage at high temperature but low ductility. Therefore bubukan metallurgy process (Powder metallurgy) is not a good method in formation with the Beryllium material.
Beryllium Beryllium Aluminum Silicate obtained from ‘Beryl’ with only generate 3.5% Beryllium. Berylium extraction process on the material and process costs exceed income forced Techniques Karen a very difficult process, especially in the process of neutralizing the toxic element.
Beryllium is sometimes used as an alloying element in copper alloy, but due to the increasing needs of Beryllium in the form of pure Beryllium Forgings for the aircraft industry and the barrel of a gun (Guided Missiles), then fungsiTembaga element Beryllium alloys with slightly reduced.
Beryllium can be formed by casting into ingot form, the form of hot-rolled bars betuk (Hot-rolling processes), extrusion and then machining. Beryllium with formation through powder metallurgical broken down into a powder which is then sintered into a beam forms. The beams Beryllium has a tensile strength of 310 N/mm2, its extension can be increased up to 10% if dikbentuk re rolling through.
Beryllium is formed by the sintering process can be machined (Machining) with Carbide cutting tools with smooth results like Grey Cast Iron. Beryllium spliced by using the method of arc welding and spot-welding between Beryllium and with other metals.
