Nagoya Metallurgy Pty Ltd — Verified Supplier
About Nagoya Metallurgy Pty Ltd - Manganese Ore Supplier in South Africa
Based in South Africa, Nagoya Metallurgy Pty Ltd currently lists eight distinct metallurgical products in its catalogue. The portfolio spans ferroalloys such as high‑carbon ferrochrome, silicon‑manganese, ferro‑silicon and ferro‑manganese, as well as zirconium granules, titanium‑zirconium concentrates, copper sludge and nickel‑copper sludge. Each item is identified by its HS‑code family, for example ferroalloys fall under HS chapter 72 (7202.xx) while zirconium products are classified under HS 81 and 26. The supplier’s catalogue reflects both alloy grades used in steelmaking and by‑product sludges recovered from metal refining.
High‑carbon ferrochrome (HS 7202.41) contains 50 - 70 % chromium with carbon levels of 4 - 10 %. Silicon‑manganese (HS 7202.30) is a ferrosilicon‑manganese alloy, and ferro‑manganese (HS 7202.11) is specified at 65 - 80 % manganese and 6 - 8 % carbon. Zirconium granules (HS 8109.19) meet a purity range of 99.2 % - 99.8 % Zr, while the titanium/zirconium concentrate (HS 2615.10) is a zirconium silicate concentrate. Copper sludge (HS 2620.19) contains 15 - 55 % copper as oxides or hydroxides with trace silver and gold, and nickel‑copper sludge (HS 7404.00) is described as a nickel‑copper recovery grade. Ferro‑silicon is listed without an HS code but is generally classified under HS 7202.20 for ferrosilicon alloys.
Product Range and Specialties of Nagoya Metallurgy Pty Ltd
Nagoya Metallurgy’s ferroalloy line includes high‑carbon ferrochrome, silicon‑manganese, ferro‑silicon and ferro‑manganese. In the global market, ferrochrome grades are commonly designated by Cr content, with standard industrial grades ranging from 45 % to 70 % Cr; the supplier’s 50 - 70 % Cr range aligns with the high‑carbon grade used for stainless‑steel production. Silicon‑manganese alloys are typically supplied at MnSi ratios of 70 - 80 % Mn and 14 - 20 % Si, and carbon content below 0.5 % for low‑carbon variants, though high‑carbon versions are also traded. Ferro‑manganese grades usually fall between 65 % and 80 % Mn with 5 % - 8 % carbon, matching the listed specification.
Zirconium granules offered at 99.2 % - 99.8 % purity correspond to the commercial grade used in nuclear fuel cladding and ceramic applications; buyers often request a particle size distribution of 0.1 - 2 mm. The titanium‑zirconium concentrate (zirconium silicate) is a typical raw material for downstream zirconium metal extraction, classified under HS 2615.10. Copper sludge and nickel‑copper sludge are by‑product concentrates recovered from leaching operations; standard practice is to provide metal assay reports indicating Cu, Ni, Ag, Au percentages and moisture content, with typical shipment in sealed drums or bulk bags.
Trade and Export Information - Nagoya Metallurgy Pty Ltd
South Africa is a recognized exporter of ferroalloys and mineral concentrates, with Durban port handling the majority of bulk shipments. Ferroalloys under HS 7202 are primarily shipped to steel‑producing regions such as China, the European Union, the Middle East and South America, where they are used in stainless‑steel and alloy‑steel production. Zirconium products (HS 8109 and 2615) are largely destined for nuclear‑energy markets in Europe, North America and East Asia, where strict purity specifications are enforced.
International buyers typically require third‑party assay certificates, ISO 9001 quality management certification, and, for EU destinations, REACH compliance documentation. Inspection agencies such as SGS or Bureau Veritas often perform pre‑shipment sampling under the CIP or FOB Incoterms. Ferroalloys are usually loaded in 20‑foot or 40‑foot containers for smaller orders, while bulk quantities are transported in open‑top or flexi‑tank containers. Zirconium granules and concentrates are often packed in moisture‑controlled wooden crates or steel drums to preserve purity during sea transit.
Sourcing from Nagoya Metallurgy Pty Ltd - Buyer Guidance
Prospective buyers should request a recent assay report that details the exact composition of each alloy, including Cr, Mn, Si, C and impurity levels for ferroalloys, and Zr purity and particle size for zirconium granules. For copper and nickel sludges, a metal recovery test report indicating Cu, Ni, Ag and Au percentages, as well as moisture and ash content, is standard practice.
Verification of ISO 9001 certification and, where applicable, REACH or RoHS compliance should be confirmed before contract finalisation. Sampling procedures may include a 5 % trial shipment or laboratory‑tested sample under the buyer’s specified standards. Buyers are advised to specify packaging requirements such as double‑walled drums for sludges or sealed moisture‑proof bags for granules to prevent contamination.
Frequently Asked Questions About Nagoya Metallurgy Pty Ltd
What ferroalloy grades does Nagoya Metallurgy offer?
Nagoya Metallurgy lists high‑carbon ferrochrome with 50 - 70 % Cr and 4 - 10 % C, silicon‑manganese (a ferrosilicon‑manganese alloy), ferro‑silicon, and ferro‑manganese containing 65 - 80 % Mn and 6 - 8 % C. These products fall under the ferroalloy HS‑code series 7202.
Which HS codes are associated with the listed products?
The catalogue assigns HS 7202.41 to high‑carbon ferrochrome, HS 7202.30 to silicon‑manganese, HS 7202.11 to ferro‑manganese, HS 8109.19 to zirconium granules, HS 2615.10 to titanium/zirconium concentrate, HS 2620.19 to copper sludge and HS 7404.00 to nickel‑copper sludge. Ferro‑silicon is typically classified under HS 7202.20 even though the code is not listed.
What purity levels are typical for the zirconium granules?
Zirconium granules are specified at a purity of 99.2 % to 99.8 % Zr. This range matches the commercial grade required for nuclear fuel cladding and high‑purity ceramic applications.
What documentation should a buyer request before purchasing copper sludge?
For copper sludge, buyers should obtain a recent assay report that details Cu content (15 - 55 % as CuO/Cu(OH)₂), trace Ag/Au levels and moisture percentage. An ISO 9001 quality management certificate is also commonly requested.
Which markets commonly import South African ferroalloys?
South African ferroalloys are frequently exported to steel‑intensive regions such as China, the European Union (e.g., Germany, Italy), the Middle East (UAE, Saudi Arabia) and Brazil in South America. These markets use the alloys for stainless‑steel and alloy‑steel production.
What are the typical shipping methods for bulk ferroalloy orders?
Bulk ferroalloy shipments are generally handled in 20‑foot or 40‑foot containers for moderate volumes, while large bulk orders are loaded into open‑top flexi‑tank containers. The common Incoterms are FOB Durban or CIF to the buyer’s destination port.
Which certifications are generally required for zirconium products destined for the EU?
For zirconium products shipped to the EU, buyers normally request ISO 9001 and ISO 14001 certificates together with REACH compliance documentation. An independent assay certificate confirming the 99.2 % - 99.8 % Zr purity and particle‑size distribution is also standard.
