Key Features & Metallurgical Advantages
Controlled Iron Impurities
Low Fe levels (0.20% max) prevent unwanted intermetallic precipitation during high-pressure die casting.
Oxide-Free Surface
Inline fluxing and ceramic foam filtration minimize dross generation and melt loss during furnace charging.
Batch Consistency
Spectrographic testing per furnace heat ensures uniform mechanical behavior across consecutive shipments.
Manufacturing & Quality Control
Reduction & Filtration: Extracted from primary reduction pots, treated with reactive gas fluxing, and passed through multi-stage ceramic foam filters to remove suspended non-metallic inclusions.
Analytical Testing: Spark Optical Emission Spectrometry (OES) performed on every individual heat before pouring.
Inspection Equipment: In-house OES spectrometers, digital weighing scales, and ultrasonic internal structure detectors.
Typical Industrial Applications
Powertrain components, transmission housings, and structural chassis nodes.
Architectural window frames, structural profiles, and industrial tubing.
Cable deoxidization, busbar manufacture, and conductor-grade wire feedstock.
Master alloy production and steelmaking deoxidizer additions.
Packaging & Logistics
Bundle Configuration
Stacked into stable bundles, banded with high-strength galvanized steel, and mounted on wooden or aluminum skids.
Moisture Defense
Stored in indoor climate-controlled bays prior to loading to eliminate surface moisture and prevent white corrosion during transit.
Container Loading
Packed into 20 ft dry containers (approx. 25 metric tons per FCL) with heavy-duty timber bracing to prevent shifting during ocean freight.

FAQ
Q: Can we arrange independent inspection before container sealing?
A: Yes. Third-party inspections by SGS, Cotecna, or equivalent agencies at the loading port are fully supported.
Q: Are physical samples available for metallurgical lab testing?
A: Yes. Representative sample pieces (1 kg to 2 kg) can be dispatched via international courier, with freight costs borne by the buyer.
Q: How is the exact net weight verified?
A: All shipments are weighed on certified calibrated industrial platform scales, with official weight tickets included in the documentation.
