China Factory Custom Make Parts Qt500 Ductile Cast Iron

For global industries demanding a perfect balance of high strength, good ductility, and excellent machinability, our China factory specializes in custom making parts from QT500-7 Ductile Cast Iron. This specific grade of ductile iron offers a guaranteed set of mechanical properties, making it an ideal engineered solution for a wide range of heavy-duty and high-stress applications. We provide comprehensive OEM/ODM services to manufacture components that deliver reliable performance and long-term durability under demanding operational conditions.

Engineered Material: QT500-7 Ductile Cast Iron

QT500-7 is a heat-treated grade of ductile iron where "QT" stands for Quenched and Tempered. The numbers designate its minimum mechanical properties: a 500 MPa tensile strength and a 7% elongation. This specific chemistry and heat treatment result in a material with superior characteristics:

• High Strength and Hardness: Offers excellent resistance to mechanical stress and wear, suitable for components bearing significant loads.

• Good Ductility and Toughness: The 7% elongation provides a vital margin of impact resistance and the ability to deform slightly without fracturing, a key advantage over brittle materials.

• Good Machinability: Despite its high strength, it maintains favorable machining characteristics, allowing for efficient production of complex geometries and precise tolerances.

• Good Fatigue Resistance: Withstands dynamic and cyclic loading, making it suitable for moving parts in machinery.

Precision Manufacturing Process for Custom Parts

Our custom make process ensures that every QT500 part meets exact specifications:

1. High-Quality Casting: We begin with advanced sand casting techniques to produce a sound, dense casting with a consistent ductile iron microstructure.

2. Controlled Heat Treatment: The castings undergo a precise Quenching and Tempering (QT) process. This thermal cycle is critical for developing the required 500 MPa tensile strength and 7% elongation, ensuring optimal combination of strength and toughness.

3. Precision CNC Machining: The heat-treated castings are finished on CNC machining centers. This step guarantees that all critical features—such as bores, threads, and mounting surfaces—are machined to exact tolerances for perfect fit and function in your assembly.

Key Applications and Performance Benefits

Our custom-made QT500-7 components are essential in numerous demanding sectors, including:
