We supply 9MB Plasma Spray Nozzle with high quality.
 

Description of 9MB Plasma Gun Nozzles

In plasma coating, the parts in it are undergoing an insensitive environment. The temporary temperature can reach over 12,000°C. Very high temperatures, high-speed flowing gases, and electric solid arcs have much influence on the nozzle. Typically, plasma gun nozzles are made of copper. But suppose you have a higher energy level operated in the spray gun and you have rigorous requirements about the coating quality. In that case, we recommend you to use tungsten-lined plasma gun nozzles.

 Advantages of Tungsten Lined Plasma Spray Nozzles:

1. Backcasting tungsten into copper nozzles can eliminate copper spitting. Compared to copper, tungsten is much more wear-resistant.

2. Owing to their better wear resistance, tungsten-lined nozzles perform better in plasma arc and process gases and can help control process drift for extended periods.

3. Compared to standard nozzles, tungsten-lined nozzles can have a longer life, and you can reduce gun maintenance.

4. By using tungsten-lined plasma nozzles, you can improve spray run consistency and do not need to adjust spray parameters.

5. Reducing waste for fewer nozzle changeovers.

6. We have multiple materials for you to choose from, including thorium-free and thorium materials. Each has its advantages.

Except for 9MB Nozzles, What Other Plasma Nozzles do We Offer:

On the market, there are many plasma torches. Except for 9MB Plasma Gun Nozzles, we also offer 3MB, 2MB11, F4, F1, and SG-100 nozzles for you and also their compatible electrodes.

If you have any needs, users are welcome to come for consultation. Our company has a group of experienced technical and sales teams who will serve you wholeheartedly.

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.
 

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.
