GH3128 is a premium-grade nickel-based high-temperature alloy specifically developed for military, aerospace, and industrial applications requiring exceptional heat resistance, oxidation stability, and structural strength. As a core material in thermal environments exceeding 900°C, GH3128 delivers outstanding reliability under stress, making it an ideal choice for mission-critical components in turbine engines, jet propulsion systems, and high-performance exhaust assemblies.
Our factory specializes in the precision manufacturing of GH3128 alloy coils, offering fully customized OEM production capabilities. Whether you're developing next-generation defense systems or seeking a dependable solution for high-temperature industrial processes, we provide end-to-end support—from material selection and prototyping to mass production and logistics—at factory-direct pricing without compromising on quality.
High-temperature resistance: Maintains mechanical integrity at operating temperatures up to 980°C (1800°F).
Oxidation and corrosion resistance: Suitable for extreme environments, including exposure to high-velocity gas flow and chemical corrosion.
Excellent creep strength and fatigue resistance: Ideal for long-term use in thermal cycling conditions.
Customizable thickness and width: Available in a wide range of coil dimensions based on application needs.
Precision-controlled metallurgy: Manufactured using advanced vacuum melting and controlled rolling technologies.
In addition to GH3128, we support a wide array of nickel and iron-based alloy grades. The following table provides a performance comparison across several popular grades:
| Alloy Grade | Max Operating Temp (°C) | Key Properties | Applications |
|---|---|---|---|
| GH3128 | 980 | High-temp resistance, oxidation control | Aerospace turbines, military jet engines |
| GH2132 | 870 | Oxidation & welding performance | Gas turbines, exhaust components |
| GH3030 | 1100 | Ductile, stable under thermal stress | Combustion chambers, industrial furnaces |
| GH3039 | 1000 | Excellent fatigue resistance | Thermal seals, engine blades |
| GH4080A | 1050 | High tensile and yield strength | Rocket engine components, pressure housings |
| GH3044 | 980 | Superior oxidation resistance | Exhaust diffusers, aerospace ducts |
We offer flexible and scalable production services tailored to meet exact customer specifications. Key OEM capabilities include:
Dimensional customization: Coil thickness from 0.1mm to 5mm, width up to 1000mm, length per order specs.
Surface finish: Bright annealed, pickled, polished, or coated based on requirement.
Precision slitting and edge processing for downstream forming or welding applications.
Strict tolerance control (±0.01mm) on critical parameters for high-performance applications.
Private labeling and branded packaging available for global OEM clients.
All alloy coils are produced under ISO 9001 and AS9100-certified manufacturing systems. Our comprehensive QA process includes:
Raw material spectral analysis and verification
In-process inspection at each rolling stage
High-temp tensile and elongation testing
Surface roughness and flatness testing
Optional third-party inspection (SGS, TUV, etc.)
GH3128 coils are trusted by leading defense contractors, aerospace firms, and industrial OEMs in over 20 countries. Common use cases include:
Aerospace: Turbine blades, combustion liners, engine seals
Defense: Heat shielding in missile and jet propulsion systems
Energy: High-efficiency gas turbine components and recuperators
Petrochemical: Crackers, reformers, and high-temp piping
In 2024, we partnered with a European aerospace integrator to deliver 5,000 meters of GH3128 coils for use in a next-gen unmanned propulsion system. Thanks to our rapid prototyping and fast turnaround, the client reduced development time by 22% and successfully passed full thermal endurance testing within six weeks of delivery.
We can provide certifications including ISO 9001, AS9100, GB/T specifications, and full chemical composition reports with each order. Export documents and compliance records are included for customs clearance.
Yes. We support sample orders starting from 1 meter. Trial production can be arranged with standard lead times of 5–7 working days.
Our minimum order quantity for OEM custom GH3128 coils is typically 30–50 kg, depending on specification. For repeat customers, we offer flexible MOQ terms and stocking agreements.
Yes. We regularly ship to clients in Germany, the United States, UAE, Turkey, and more. International logistics options include air freight, sea freight (LCL/FCL), and express courier service.
Standard production lead time is 10–15 business days. For urgent orders, expedited service can be arranged with delivery in as fast as 7 days (subject to specification and inventory).
