Core difference between ductile iron platform and ordinary cast iron platform (gray iron platform)

Core difference between ductile iron platform and ordinary cast iron platform (gray iron platform)

Simply put, ductile iron has good toughness NAICHONGJI、 Not easy to break, high price; Ordinary cast iron (gray iron)=stable precision NAIMO、XINGJIABIGAO，ZUICHANGYONG。

1. Different materials

-Ordinary cast iron platform (gray cast iron HT200/HT250)

Graphite is in the form of flakes and is the most mainstream material for inspection, marking, and assembly platforms in ZUICHANGYONG.

-Ductile iron platform (QT400-18/QT500-7)

Graphite is spherical in shape and belongs to GAOQINGDU ductile cast iron, with properties one level stronger than gray iron.

2. Performance Comparison (ZHONGDIAN)

① Hardness& precision

-Gray iron: Moderate hardness, stability, not easily deformed, suitable for GAOJINGDU inspection and marking.

-Ductile iron: hardness GENGGAO, high strength, rigidity GENGQIANG.

② Resilience and impact resistance (ZUIDA distinction)

-Gray iron: brittle, prone to breakage and cracking under strong impact, afraid of severe collision.

-Ductile iron: Good toughness, resistant to impact and vibration, not easily broken, and not easily damaged by heavy objects or hammers.

③ NAIMOXING

Both are NAIMO, with little difference in daily use; Overloaded frequent impact scenes make the ball iron more powerful.

④ Deformation amount

Gray iron: has good natural aging and maintains stable accuracy over long-term use;

Ductile iron: QIANGDUGAO, with slightly stronger resistance to deformation.

3. How to choose the applicable scenario

Select 'Ordinary Grey Iron Platform'

-Routine inspection, marking, assembly, and fitter workbench

-Indoor stable use without severe impact

-Pursuing cost-effectiveness and stable accuracy (90% of customers choose this)

Choose the 'Ball Iron Platform'

-Heavy load, frequent lifting, heavy object impact, and large workshop vibration

-Welding platform, fixture, heavy-duty assembly

-Require impact resistance, resistance to breakage, and use of SHOUMINGCHANG

4. Price difference

Ductile iron platforms are about 20% to 40% more expensive than ordinary cast iron, with a cost of GENGGAO.
