Plasma Thermal Spray Gun Consumables Nozzle and Electrode

Product Description

We supply all various of plasma spray nozzle(anode) and plasma electrode(cathode)

There are different types of plasma spray guns including F4, F1,9MB, SG100 and so on. 
We are professional manufacturer for plasma spray nozzles and electrodes for these thermal spray guns.
We have been in metallurgy for many years and work with customers in thermal spray long time. So we know material and we know the application.
 

Long service life and good heat transfer

We use back casting technology to combine tungsten and copper. This technology can ensure non-defect bonding(NDB) between these two materials with best thermal conductivity and optium heat resistance.


We can offer standard parts such as plasma spray nozzles and plasma spray electrodes and also parts based on drawings

As we all know, the most critical components of plasma thermal spray guns such as F4, F1, 9MB, 7MB, 3M7, SG-100,SinplexPro,TriplexPro and so on are the nozzle and electrode . These two products are also consumable parts and are one of the most important consumables in plasma thermal spraying.
Our company is a manufacturer specializing in the production of plasma spray electrodes and nozzles (also known as plasma cathodes and anodes, tungsten copper cathodes, and tungsten copper anodes).

Advantages of plasma spray nozzles and electrodes produced by our company:
1. Our company has been engaged in the production of pure tungsten and tungsten alloy materials for many years, and has an in-depth understanding of the structure and properties of materials. For the tungsten electrode used in plasma spraying electrodes, based on our full understanding of the application, we have made more improvements and treatments to the material structure to meet the material requirements of plasma spraying. By densifying the tungsten electrode, a finer, more uniform grain structure is formed. The modified tungsten alloy has relatively high hardness and density, fast arc starting, excellent resistance to arc burning loss, and long life.

2. Our company's plasma spraying electrodes and nozzles use unique back-casting technology to achieve seamless bonding between tungsten and copper. The bonding strength can be as high as 127MPa, while the traditional bonding strength is less than 100MPa. Compared with traditional brazing, joints made by back-casting have higher bonding strength between tungsten and copper, larger contact area, more uniform resistance, and stronger heat dissipation ability, making the nozzle and electrode more stable and more durable as well as long service life.

3. We produce tungsten electrodes of different materials (good arc starting performance and ablation resistance). Based on customer usage conditions, we can provide more suitable materials for customers to choose.
 

Material	Impurity content (%)	Electron work function (eV)
Lanthanum tungsten	<0.2	2.8-3.2
Cerium tungsten	<0.2	2.7-2.8
Thorium tungsten	<0.2	2.0-3.9

4. Based on the research and analysis of plasma spray guns, the electrodes and nozzles produced by our company can perfectly adapt to the original spray guns, and no additional adjustment of spraying parameters is required during replacement. We have a complete product series, and the plasma spray electrodes and nozzles we produce can be widely used in F4, 9M, SG-100 and other spray guns of Metco, GTV, FST, AMT AG, Praxair and other companies.
5. We have rich experience in producing various cathodes and anodes, which can be customized and processed according to customer samples or drawings. We can also provide semi-finished products with seamless combination of tungsten and copper.
