Product Description Product DescriptionWe supply 6mm plasma spray nozzle for F4 gun.An F4 nozzle is a specialized component in F4MB-XL plasma spray gun, designed to optimize the flow and ionization of nitrogen gas (or nitrogen-based gas mixtures) during plasma spraying. It plays a critical role in generating stable plasma jets for material deposition.Key Features and Functions:Material and Construction:Typically made of copper-tungsten composite or tungsten alloy, ensuring high thermal conductivity and resistance to arc erosion.Uses back-casting (CBT) technology to bond tungsten and copper seamlessly, enhancing durability and heat dissipation.Gas Flow Optimization:Designed to handle nitrogen gas (or nitrogen-argon/hydrogen mixtures) as the plasma-forming medium, improving coating quality and process efficiency.Ensures uniform gas distribution and stable arc formation, critical for high-temperature plasma generation (up to 16,000°C).Performance Benefits:Compatible with high-power plasma spray systems (e.g., Metco F4-MB, SG-100), supporting currents up to 1000A and voltages of 30-100V.Reduces nozzle wear and extends service life due to anti-erosion tungsten materials.Applications:Used in ceramic, metal, and carbide coatings for aerospace, automotive, and industrial components.Ideal for high-purity nitrogen environments where oxidation must be minimized.Technical Specifications (Example):Gas Flow Rate: 6-24 NLPM (nitrogen/hydrogen mixtures).Spray Distance: 150±3 mm.For detailed operational parameters or customization, refer to manufacturer guidelinesF4 electorde and nozzle models:Product modelProduct nameRelated product modelWLE-F4F4 electrode1072006WLN-F4-5F4 nozzle1088066WLN-F4-6F4 nozzle1072007WLN-F4-7F4 nozzle1088062WLN-F4-8F4 nozzle1088057There are many F4 electrode manufacturers on the market, but many of them can only make similar sizes, but there are many differences in service life and performance. As a professional manufacturer, we not only know how to produce, but also how to improve and understand customer's use, so we can provide more professional online services.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. Our AdvantagesAdvantages 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. MaterialImpurity content (%)Electron work function (eV)Lanthanum tungsten<0.22.8-3.2Cerium tungsten<0.22.7-2.8Thorium tungsten<0.22.0-3.94. 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.After Sales Service We can ensure our all products which are seamless bonding,no gas foam generating,and assure concentricity,if any defect has been found which are due to our cause,we can replace them for free and send you along with shipment for next time.
