About Emkex Zhejiang Advanced Materials Co.,Ltd - Magnets & Magnetic Products Supplier in China

China, specifically the Zhejiang region, hosts nine active product listings from Emkex Zhejiang Advanced Materials Co.,Ltd. The supplier focuses on the Magnets & Magnetic Products category and provides items that fall under HS‑code families 8505, 8543 and 8482. The catalogue includes ferrite magnets, samarium‑cobalt (SmCo) alloys, AlNiCo alloys, flexible rubber magnets, fridge magnets, NdFeB sintered magnets, magnet grids, magnetic balls and ball magnets. Each entry specifies the material composition, such as strontium or barium ferrite for ceramic types, Nd₂Fe₁₄B for neodymium alloys, and stainless‑steel 440C for magnetic balls, together with the corresponding HS code. The product set therefore covers both bulk magnetic powders and finished magnet assemblies that are typical export items from China.

The nine listings are grouped by magnetic material and form factor. Ferrite, flexible rubber and fridge magnets share HS code 8505.19 and are described as ceramic or polymer‑bound ferrite powders. SmCo, AlNiCo, NdFeB sintered and ball magnets are recorded under HS code 8505.11, indicating permanent magnet alloys with defined rare‑earth or transition‑metal content. Magnet grids are classified under HS code 8543.70 and consist of NdFeB blocks housed in stainless‑steel 304 frames, while magnetic balls use HS code 8482.10 and are made from martensitic stainless steel 440C. The supplier’s list therefore spans raw magnetic materials, flexible composites and precision‑shaped permanent magnets.

Product Range and Specialties of Emkex Zhejiang Advanced Materials Co.,Ltd

The catalogue presents a spectrum of permanent magnet technologies. Ferrite magnets (SrFe12O18 or BaFe12O18) are commonly supplied in grades such as M‑30 to M‑45 with a typical maximum energy product (BHmax) of 3‑5 MGOe, while flexible rubber magnets use the same ferrite powders bound in polymer matrices for thin‑profile applications. SmCo alloys listed as Grade XG16‑XGS32M provide high temperature stability up to 300 °C and coercivity above 1 200 kA/m. AlNiCo alloys, with aluminium 8‑12 %, nickel 15‑26 % and cobalt 5‑40 %, are offered in grades 5, 8 or 10, delivering moderate energy products (1‑2 MGOe) and excellent dimensional stability. NdFeB sintered magnets, including grades N35, N42 and N52, reach BHmax values of 35‑52 MGOe and are widely used in automotive and renewable‑energy sectors. Magnet grids combine NdFeB blocks with stainless‑steel 304 housings for modular assembly, and magnetic balls and ball magnets are supplied in stainless‑steel 440C for mechanical sealing or positioning applications.

Trade and Export Information - Emkex Zhejiang Advanced Materials Co.,Ltd

China is a global exporter of permanent magnets, and the HS‑code 8505 series captures the bulk of these shipments. Buyers in Europe, North America and Southeast Asia import Chinese magnets for automotive electric‑motor drives, consumer electronics, wind‑turbine generators and industrial automation. Standard export documentation often includes a commercial invoice, packing list, certificate of origin and, when required, test reports complying with IEC 60404 safety standards. Importers typically request ISO 9001 quality‑management certification, RoHS and REACH compliance for electronic‑grade magnets, and third‑party magnetic performance certificates that confirm BHmax, coercivity and temperature coefficients. Shipping is normally arranged on 20‑ft or 40‑ft containers under FOB or CIF terms, with magnets packed in anti‑corrosion coated boxes or sealed polymer bags on wooden pallets to prevent mechanical damage during transit. Chinese export regulations for magnetic materials also require proper labeling of hazardous content if any rare‑earth powders exceed threshold limits.

Sourcing from Emkex Zhejiang Advanced Materials Co.,Ltd - Buyer Guidance

When evaluating Emkex Zhejiang Advanced Materials Co.,Ltd, buyers should obtain a detailed material data sheet for each magnet type, confirming alloy composition, magnetic grade, BHmax, coercivity and operating temperature range. Request third‑party test reports that include flux density measurements (Gauss), demagnetization curves and corrosion‑resistance assessments, especially for NdFeB and SmCo grades that are sensitive to moisture. Verify that the supplier can provide ISO 9001, IEC 60404 and RoHS/REACH compliance documents, and confirm packaging specifications such as anti‑static wrapping, moisture‑proof bags or stainless‑steel crates for high‑value items. Clarify the minimum order quantity, lead time and whether sample units (typically 5‑10 pieces) are available for preliminary performance testing before committing to full production.

What magnet types are listed in the supplier's catalogue?

The catalogue includes ferrite, samarium‑cobalt (SmCo), AlNiCo, flexible rubber, fridge, NdFeB sintered, magnet grid, magnetic ball and ball magnet products. Each type is identified with a specific material description and an HS code that aligns with permanent‑magnet export classifications.

Which HS codes correspond to the listed products?

Ferrite, flexible rubber and fridge magnets are classified under HS 8505.19. SmCo, AlNiCo, NdFeB sintered and ball magnets use HS 8505.11. Magnet grids fall under HS 8543.70, while magnetic balls are recorded under HS 8482.10. These codes are standard for permanent magnet and magnetic component exports.

What are typical specifications for the NdFeB magnets offered?

NdFeB magnets in the catalogue are made from sintered Nd₂Fe₁₄B alloy, commonly supplied in grades such as N35, N42 or N52. Typical specifications include a BHmax of 35‑52 MGOe, coercivity above 800 kA/m and a maximum operating temperature of 80‑150 °C depending on the grade.

Which certifications should a buyer request from a Chinese magnet exporter?

Buyers usually request ISO 9001 quality‑management certification, IEC 60404 safety test reports, and compliance statements for RoHS and REACH. These documents demonstrate that the magnets meet international safety, environmental and quality standards.

How are the magnets typically packaged for international shipment?

Magnets are generally packed in anti‑corrosion coated cardboard boxes or sealed polymer bags, then placed on wooden pallets. Full containers (20‑ft or 40‑ft) are loaded under FOB or CIF terms, with additional moisture‑proofing for high‑grade NdFeB items.

What minimum order quantities are common for NdFeB magnets?

Standard minimum order quantities for NdFeB grades range from 500 to 1 000 pieces per grade, with higher quantities required for custom shapes or very high‑performance specifications.

What lead time can a buyer expect for a new order?

Lead times for Chinese magnet exporters typically range from 30 to 45 days after final technical specifications are approved and any required sample testing is completed.

Can a buyer obtain sample magnets before placing a full order?

Yes, suppliers usually provide a limited number of sample pieces (5‑10 units) for testing magnetic flux density, coercivity and temperature stability. Sample provision is often subject to a nominal fee and non‑returnable terms, allowing the buyer to verify performance before committing to larger volumes.
