Tungsten carbide sandblasting nozzle details:
Carbide Sandblasting Nozzles – Product Features：
1. Superior Hardness, Ultimate Wear Resistance
Hardness reaches HRA 89-93: The material’s hardness is second only to diamond, giving the nozzle extremely high resistance to erosion.
Extra-Long Service Life: Compared to ordinary ceramic nozzles, lifespan is increased by 5-10 times; compared to steel nozzles, lifespan is increased by more than 20 times. Significantly reduces replacement frequency and downtime.
2. Unique Venturi Design, Doubled Efficiency
Acceleration Principle: Utilizes a precisely calculated Venturi flow channel design (inlet contraction – straight throat – outlet expansion). When compressed air carrying abrasive particles passes through, the airflow velocity can increase to above the speed of sound.
2.1 Significant Results:
Abrasive exit velocity increased by 30%-50%;
Stronger impact force, cleaning efficiency increased by more than 40%;
Concentrated jet beam, larger coverage area, ensuring uniform surface treatment.
3. Excellent Impact Resistance and Toughness
Scientific Formula: Utilizing a “hard phase (WC) + binder phase (Co)” structure, by adjusting the cobalt content (e.g., YG6, YG8 grades), it maintains high hardness while imparting sufficient toughness to the matrix.
Durable and Reliable: Capable of withstanding continuous high-speed impacts from large, high-hardness abrasive particles (such as steel shot and copper ore sand) without easily cracking, chipping, or breaking.
4. Precision Machining and Dimensional Accuracy
High-Precision Forming: Employing isostatic pressing or molding, combined with subsequent precision grinding of the inner and outer diameters.
Small Internal Hole Tolerance: The inner diameter tolerance is controlled within ±0.05mm, with a mirror-like smooth inner wall. This ensures smooth airflow channels, reduces eddy current losses, thereby maintaining a stable injection angle and pressure, and reducing energy consumption.
5. Good High-Temperature Resistance and Chemical Stability
High-Temperature Resistance: Can operate for extended periods in high-temperature environments (withstanding temperatures up to 400°C-600°C) without performance degradation.
Corrosion resistant: It has good resistance to chemical media such as acids and alkalis, and is suitable for working environments in sandblasting rooms that are humid or contain corrosion inhibitors. It is not easy to rust or corrode.
6. Wide range of applications: covering various industrial sandblasting operations such as shipbuilding and repair, auto parts, steel structure corrosion protection, mold cleaning, and surface strengthening/descaling of aerospace components.
FAQ for Tungsten carbide sandblasting nozzles:
Q1: What are a tungsten carbide sandblasting nozzles?
A: Tungsten carbide sandblasting nozzles are critical wear-resistant components of sandblasting equipment. Installed at the outlet of the sandblasting gun, they constrain the mixture of compressed air and abrasive media to form a high-speed, focused abrasive jet, enabling processes such as rust and paint removal, surface roughening, deburring, and finishing. The core working section is made of sintered tungsten carbide (WC plus a metallic binder phase, typically cobalt), making it the mainstream nozzle material in industrial sandblasting for its balance of wear resistance and impact toughness.
Q2: What tungsten carbide grades are commonly used for sandblasting nozzles?
A:YG6 (6% Co), YG8 (8% Co), and YG10 (10% Co). Among them, YG8 is a general-purpose sandblasting nozzle grade offering balanced performance; YG6 features higher hardness and superior wear resistance, making it suitable for stable operating conditions without impact; YG10 offers superior toughness, making it ideal for high-pressure applications and scenarios involving frequent start-stop cycles.
Q3: What is the hardness of a tungsten carbide sandblasting nozzle?
A: The hardness range of the tungsten carbide matrix for standard sandblasting nozzles is HRA 88.5–91.5; a lower cobalt content results in higher hardness and superior wear resistance, though impact toughness decreases correspondingly.
Q4: Can tungsten carbide sandblasting nozzles be customized?
A: We support customization; please provide drawings or samples.
Q5: What is your lead time?
A: In-stock items can be shipped within 2–3 days. New non-standard customized orders take 7–15 working days, subject to processing complexity.
Q6: What is your MOQ for custom carbide preforms?
A: Small trial order MOQ: 5 pieces for new development.
