BS2789 Grade 500-7 Cast Iron | Properties, Applications & Supplier – niftyalloys

BS2789 Grade 500-7 Cast Iron is a high-strength spheroidal graphite iron, also known as nodular cast iron or ductile iron, which is used very commonly in engineering for parts requiring a combination of strength, toughness, and wear resistance. Falling under the British Standard BS2789, the grade assures high performance for demanding industries like automotive, heavy machinery, construction, railways, and hydraulics.

At nifty alloys LLC, we supply and export BS2789 Grade 500-7 Cast Iron conforming to international standards, offering the customers the best combination of quality, performance, and price in Dubai, the Middle East, and across the globe.

What is BS2789 Grade 500-7 Cast Iron?

Cast Iron, also known as Spheroidal Graphite Iron or Nodular Cast Iron, contains graphite in the form of nodules (spheres) instead of flakes. This microstructure gives it enhanced toughness, high fatigue strength, and better impact resistance compared to conventional grey cast iron.

BS2789 500-7 is specifically designed to deliver:

• Tensile strength of around 500 MPa
• Elongation of up to 7%
• Excellent wear resistance and machinability

Benefits of Cast Iron (SG)

• Recyclable Material: Can be remelted and reused.
• Energy Efficient: Requires less processing than forged steels.
• Lightweight Yet Strong: Reduces overall equipment weight while maintaining durability.
