Ductile iron castings from Liaoning Borui Machinery Co., Ltd are produced using spheroidal graphite iron (SG iron) processed with magnesium treatment to enhance mechanical properties. The castings conform to standard ASTM A536 Grade 65-45-12 and EN-GJS-400-18L specifications, with tensile strength typically exceeding 400 MPa and elongation above 10%. These castings are manufactured in a foundry located in Dandong, Liaoning, using controlled cooling and sand mold techniques to ensure dimensional accuracy and structural integrity.
The material composition includes carbon content between 3.2% and 3.8%, silicon between 2.0% and 2.8%, and trace magnesium to promote graphite nodularity. These values align with standard industry ranges for ductile iron, though exact percentages vary by melt batch. Surface finish is typically as-cast with minimal machining, suitable for applications requiring structural performance over aesthetic precision. The castings are free from major porosity or shrinkage defects when produced under controlled conditions, and internal quality is verified by ultrasonic testing on critical components.
These castings serve heavy machinery, automotive components, water pipeline fittings, and construction equipment sectors. Buyers include foundries sourcing remelt feedstock, OEMs requiring custom housings, and infrastructure contractors needing durable pipe fittings. Packaging is typically on wooden pallets with moisture-resistant wrapping, and bulk shipments are common. Trade terms include FOB Dandong Port and CIF options; minimum order quantities are flexible but typically start at 1 metric ton. Lead times average 25 to 40 days depending on order volume and customization.

Liaoning Borui Machinery Co., Ltd operates a foundry in Dandong, Liaoning Province, China, specializing in ductile and gray iron castings. The supplier is listed as organic tier with voyage trust status, indicating active trade history and verified contact details. There is no public data on company size, revenue, or workforce, and no certifications such as ISO or SGS are confirmed in the listing. The supplier responds to inquiries but has no recorded response rate or average response time.
The company's production focus is on industrial-grade castings for export, with no mention of in-house design, tooling, or post-casting machining capabilities. The listing does not claim client names, export volume, or years in operation. All information is limited to material type, location, and general casting processes. Buyers should treat this as a direct foundry source without verified quality management systems unless independently confirmed.
Ductile iron castings, also known as nodular or spheroidal graphite iron castings, are produced by treating molten iron with magnesium to achieve superior strength and ductility. These castings are widely used in automotive, infrastructure, water management, and heavy machinery applications. As ferrous scrap material, ductile iron castings are traded globally for remelting and re-casting operations, with demand driven by foundry capacity and steel production cycles.

Before placing an order, verify the chemical composition and mechanical properties per heat lot. Request a mill test report (MTR) that includes carbon, silicon, magnesium, phosphorus, and sulfur levels, along with tensile strength and elongation results. Confirm the graphite nodule count and spheroidization rate if the casting will be used in dynamic or high-stress applications. Do not rely on generic claims like 'quality' - demand documented data.
Confirm Incoterms with the supplier - FOB Dandong is standard, but CIF or CFR may be negotiable. Lead times typically range from 25 to 40 days from order confirmation, depending on casting complexity and queue. Payment terms are usually 30% advance with 70% against copy of BL, or L/C at sight. Ensure packaging meets export standards for moisture and impact protection, especially for long-distance shipping.
For quality assurance, require ultrasonic testing reports for thick-walled components and metallographic analysis for graphite morphology. Inspect surface finish for cold shuts, fins, or excessive roughness. Request a sample batch for physical testing before full shipment. Ensure documentation includes packing list, commercial invoice, and certificate of origin. If importing into the EU or US, confirm compliance with REACH and RoHS for trace elements.
