What is Purple Tungsten Used for

Tungsten is an extremely hard and fragile material. The main properties incorporate an exceptionally high softening point, a low fume pressure, and the most elevated hardness and strength, everything being equal. Notwithstanding the exceptionally high thickness and warmth obstruction, tungsten has awesome electrical and warm conductivities. Tungsten has great erosion obstruction against most acids and soluble bases. 

Tungsten electrodes are utilized for welding measures, for example, in opposition welding, particularly when materials like copper, bronze, or metal are welded. The new tungsten terminal will ultimately turn into the main tungsten as Thoriated electrodes become more diligently imported because of the radioactive substance. 

What is Purple Tungsten Used For?

The purple tungsten electrode is a genuine non-radioactive option in contrast to the thoriated tungsten electrode. 

  • The E3 electrode, as it is known, has many advantages! 
  • The electrode tip stays cooler than its thoriated cousin 
  • It has prevalent repeatable start attributes 
  • Has expanded circular segment dependability 

Advantages from decreased consumption off 

  • Can convey a higher current than the other options 
  • Further developed tip degradation of the electrode tip 

For instance - when utilizing a similar current thickness, the E3 electrodes are around 900 degrees C, not exactly a 2% Th (Red Tip) tungsten. Not something to be sniffed at. 

The imaginative Rare Earth Blend tungsten electrode contains 98.34% tungsten, 1.5% lanthanum, 0.08% Zirconium, and 0.08% Yttrium. It is the ideal substitute for red thoriated electrodes. They perform well in DC applications and are extraordinary for welding copper combinations, nickel compounds, titanium amalgams, and tempered steel. 

Effects of Different Tungsten Components

Effects of Different Tungsten Components

  • Zirconium oxide keeps the vanishing lower and empowers a more steady bend contrasted with unadulterated tungsten electrodes. 
  • Cerium oxide gives a tungsten terminal excellent start and reignition properties. 
  • Lanthanum oxide has great start properties and gives the electrodes a more drawn-out help life. 
  • Thorium oxide makes a truly steady bend; anyway, it is radioactive, which implies it is extremely hurtful to wellbeing. When thorium smoke or residue is breathed in, it very well may be stored in the lungs and lead to inward radiation exposure. As an outcome, it has been restricted as an added substance to tungsten electrodes in numerous nations. 
Rare Earth Mix Tungsten Electrode (WP green) empowers an exceptionally consistent circular segment. At the same time, oxide-containing electrodes are simpler to touch off, have a high current conveying limit, and have a more extended assistance life.
