How HDC Cast Superalloy
Learn about our comprehensive casting service workflow
Superalloy is hard to process by manufacturing methods like CNC machining, forging, and welding due to its superior mechanical properties.
The most commonly used method to process superalloy is investment casting. Its ability to cast complex internal cavities, thin-walled structures, curved surfaces, and nearly any shape of parts makes it preferred by industries that require high-temperature resistant components.
As a factory specializing in investment casting, we have over 15 years of experience and provide custom superalloy investment casting services tailored for your projects.
HDC has developed a detailed casting process and strictly implemented it to ensure the quality of superalloy castings, and the complete workflow is shown in the figure.

What is Super Alloy
Superalloy, also known as “high-temperature alloy”, is a type of high performance metal material specially developed for applications under extremely high temperatures over 1000°C.
Key Properties of Superalloy
- Superior high-temperature strength
- Excellent creep resistance
- Excellent resistance to oxidation and corrosion
- Good fatigue resistance
Types of Super Alloy
Based on the main matrix elements, superalloys can be primarily divided into three categories:
- Nickel-based: The most widely used, offering the best overall high temperature performance.
- Cobalt-based: Superior resistance to thermal corrosion and thermal fatigue at higher temperatures, but also has higher density and cost.
- Iron-nickel-based: Relatively low cost, performance between nickel-based and heat-resistant stainless steels, use at lower temperatures or in environments that require less extreme.
In addition to the base elements, the key alloying elements of superalloy include chromium, aluminum, titanium and some elements with extremely high melting points, such as tungsten, molybdenum, rhenium, tantalum and niobium. By adjusting the content of various elements, the performance of superalloy can be precisely controlled to adapt to various application scenarios.
FAQ
We cast parts from 0.5 kg to 50 kg with tolerances as tight as ±0.1 mm. Complex geometries with thin walls (as thin as 0.5 mm) are achievable.
We use vacuum melting and advanced shell systems to minimize impurities. Each batch undergoes chemical analysis and mechanical testing per ASTM standards.
We accept common CAD file formats, including STEP, DWG. PDF drawings are also acceptable.
For prototypes, the lead time is typically around 4-6 weeks, and for production runs, typically 8-12 weeks.
