Iron Trading Across Industries at Struma B.V.

Iron, a cornerstone of modern industry, is primarily produced in two forms: wrought iron and cast iron. These materials have distinct properties and uses, making them indispensable in various applications.

Wrought Iron: Art and Architecture

Wrought iron is renowned for its malleability and low carbon content, making it ideal for decorative pieces like the intricate works found in 15th and 16th-century churches. Today, it continues to be valued for custom-made items such as railings, doors, and benches due to its aesthetic appeal and workability.

Cast Iron: Versatility and Strength

Cast iron, known for its excellent fluidity and casting ability, contains 2–4% carbon and 1–3% silicon which enhances its casting performance. Unlike wrought iron, it is not worked with hammers but is cast in molds to make products like:

• Pipes
• Machinery
• Automotive parts
• Cooking utensils
• Anchors

Properties and Advantages: Cast iron is preferred for its ability to be cast into complex shapes and its cost-effectiveness. It offers superior machinability, vibration dampening, compressive strength, wear resistance, and enhanced corrosion resistance through minor additions like silicon and chromium.

Types of Cast Iron

Diverse cast iron types are crafted using different heat treatments and processing techniques, each suitable for specific applications:

• Gray Iron: Known for its damping capacity and thermal conductivity, used in engine blocks, manifolds, and machine housings.
• White Iron: Hard and brittle, ideal for abrasive environments like mill linings and pump housings.
• Malleable Iron: Heat-treated white iron that offers better malleability, used in heavy-duty applications like railroad and construction machinery.
• Ductile Iron: Contains magnesium; notable for its impact resistance, used in automotive and infrastructure components.
• Compacted Graphite Iron: Offers a mix of strength and ductility, suitable for high-stress engine blocks and brake discs.
