Key Product Advantages
✅ Premium CW617N Material Performance
CW617N lead brass is the industry standard for instrument fittings, valve components, and meter parts, offering optimal machinability, excellent thermal conductivity, and outstanding resistance to dezincification, ensuring long-term service in harsh fluid and environmental conditions.
✅ Superior Forging Process Quality
Our precision closed-die hot forging process creates a dense, defect-free grain structure, delivering 20-30% higher tensile strength and fatigue resistance compared to cast alternatives, making these parts ideal for high-pressure, high-reliability instrument applications.
✅ Customized Manufacturing Solutions
We support fully customized forging solutions, tailored to your specific instrument designs, dimensional requirements, and application scenarios, from small-batch prototypes to large-scale mass production.
✅ Strict End-to-End Quality Control
Every component undergoes 100% dimensional inspection, surface quality checks, material composition verification, and pressure tightness testing to ensure full compliance with international standards and your exact specifications.
✅ Wide Industrial Application Scope
Perfect for pressure gauges, flow meters, control valves, thermometers, water meters, HVAC systems, and other industrial instrumentation requiring robust, corrosion-resistant brass components.
CW617N Lead Brass Forging Process Details
Material & Process Fundamentals
CW617N (CuZn40Pb2) is a high-performance lead brass alloy specifically engineered for precision hot forging. Its unique (α+β) dual-phase microstructure, combined with finely dispersed lead particles, delivers exceptional hot workability and machinability, making it the ideal material for complex instrument components like meter housings, valve bodies, and gauge fittings. Our forging process is fully optimized for CW617N to ensure defect-free, high-strength parts that meet the strict requirements of industrial instrumentation.
Drop forging is a highly valued metal forging process that uses a pair of impression dies and a heavy hammer to form and compress metal bars or billets into complex shapes. The steel forged clevis end yoke are with high density, good mechanical properties and wear resistance, compared with casting rod end yoke.
Baoding Guokun’s drop forging process
| Close die forging or mold forging process | |
| Material Selection | Choose the appropriate metal (e.g., carbon steel, alloy steel, aluminum, or titanium) based on the component’s requirements. Ensure the required steel meets the required chemical composition and quality standards. Baoding Guokun will test the material’s chemical composition before storage. |
| Billet Preparation | Cut the raw material into billets of the required size. And heat the billet to the forging temperature (typically 1100°C–1200°C for steel) to make it malleable |
| Die design and preparation | Design the dies (upper and lower) to match the final shape of the component. Dies are typically made from high-strength tool steel and are precision-machined. |
| Forging | Place the heated billet into the lower die. Apply pressure using a hydraulic or mechanical press to force the metal into the die cavity. The metal fills the die, taking the shape of the mold |
| Flash Formation & Trimming | Excess metal, called flash, flows out of the die cavity through small gaps. Remove the flash and excess material using trimming dies or machining |
| Cooling | Allow the forged part to cool slowly (for some materials) or control the cooling rate to achieve desired properties. |
| Heat Treatment | Perform heat treatment processes like normalizing, quenching, and tempering to enhance mechanical properties (e.g., hardness, toughness) |
| Finishing | Machine the forged part to achieve precise dimensions and surface finish. Apply surface treatments (e.g., sand blasting, coating) if required |
