Pig Iron: Sourcing, Types, and Buyer's Guide for 2025


Pig iron is a crucial raw material in the metals and alloys industry, widely used in steel production and foundry applications. This guide covers everything from sourcing reliable suppliers in China to understanding its types and functions.


How to Find Reliable Pig Iron from China in 2025


China remains a leading exporter of pig iron, offering competitive prices and large-scale production capabilities. To find trustworthy suppliers:

  • Check certifications like ISO 9001 and SGS reports.
  • Review customer feedback and case studies.
  • Request samples to test quality before bulk orders.

What Buyers Should Know Before Buying Pig Iron from China


Before purchasing, consider:

  • Shipping costs and logistics, as pig iron is heavy.
  • Import tariffs and regulations in your country.
  • Supplier reliability and production capacity.

Types of Pig Iron


There are three main types:

  • Basic Pig Iron: High in silicon, used for steelmaking.
  • Foundry Pig Iron: Contains more carbon, ideal for casting.
  • High-Purity Pig Iron: Low impurities, used in specialty alloys.

Functions and Features of Pig Iron


Pig iron is valued for its high carbon content (3-4%) and ability to be remelted for steel production. Key features include:

  • Excellent fluidity when molten.
  • High tensile strength in cast forms.
  • Cost-effectiveness compared to other iron sources.

Scenarios of Pig Iron


Common applications include:

  • Steel production in blast furnaces.
  • Manufacturing automotive parts.
  • Construction materials like beams and pipes.

How to Choose Pig Iron


Select based on:

  • Your industry requirements (e.g., steelmaking vs. casting).
  • Carbon and silicon content specifications.
  • Supplier reputation and after-sales support.

Pig Iron Q & A


Q: What’s the difference between pig iron and wrought iron?
A: Pig iron has higher carbon content and is brittle, while wrought iron is nearly pure iron with fibrous slag inclusions.


Q: How is pig iron transported internationally?
A: Typically shipped in bulk carriers or containers, often with moisture-proof packaging.


Q: Can pig iron be recycled?
A: Yes, it’s commonly remelted in steel production, making it a sustainable material.


Q: What’s the typical lead time for orders from China?
A: Usually 15-30 days, depending on quantity and shipping method.


Q: How do I verify pig iron quality?
A: Request mill test certificates (MTCs) or conduct third-party lab testing.
