从China供应商批量进口Alnico Magnet

Universal (Ningbo) Magnetech Co., Ltd. supplies cast and sintered Alnico magnets manufactured in Ningbo, Zhejiang Province, China. These magnets derive their magnetic properties from an iron-aluminium-nickel-cobalt alloy, with copper and titanium sometimes added to refine grain structure and coercivity. The supplier notes ISO and SGS certification claims in its source materials, though buyers should independently verify current certificate validity and scope. Alnico grades span Alnico 2 through Alnico 9, with energy products (BH)max ranging from 1.5 to 9.0 MGOe depending on grade and orientation, and Curie temperatures typically 540 to 860 degrees Celsius.

The material structure differentiates cast from sintered variants: cast Alnico offers higher magnetic output and is shaped by foundry methods into complex geometries, while sintered Alnico permits tighter dimensional tolerances and is preferred for smaller, intricate components. Typical remanence (Br) values for common grades fall between 7,000 and 13,500 Gauss, with coercive force (HcB) from 550 to 2,000 Oersteds. The alloy's metallurgical stability means magnetic properties change minimally across temperature swings that would degrade ferrite or rare-earth alternatives. Surface finish is usually ground or polished to specified roughness, with common coatings including none (bare metal), nickel, or paint for environmental protection.

Primary applications include precision instrumentation, electric guitar pickups, aerospace sensors, loudspeaker drivers, and legacy electric motor designs where elevated temperature operation precludes NdFeB or SmCo. Buyers in automotive, energy, and industrial equipment sectors source Alnico when thermal stability outweighs raw magnetic output. Trade terms from this Ningbo supplier include FOB and CIF options, with payment by L/C or T/T. Minimum order quantities are stated as flexible in source materials, though exact figures require direct confirmation with Universal (Ningbo) Magnetech. Lead times and specific packaging configurations are not specified in available data and should be clarified before order commitment.

Universal (Ningbo) Magnetech Co., Ltd. is located at No.999 Eastern Section Huancheng South Road, Ningbo 315040, Zhejiang Province, China. The supplier is classified as 'imported' tier within platform data, with 'harbor' trust tier designation. Response rate is recorded at 0.00 percent with zero average response hours, indicating no historical response data is available through the platform interface. The supplier address places it in Ningbo's core industrial zone, a region with established magnetic materials manufacturing infrastructure.

The source description positions the company as offering Alnico magnets with flexible minimum order quantities and international trade facilitation. No information is provided about founding year, factory floor space, employee count, annual revenue, or specific clientele. Buyers should independently verify production capacity, quality control protocols, and whether the supplier operates as manufacturer, trader, or hybrid. The mention of ISO and SGS certifications requires direct validation, including certificate numbers and audit scopes, before reliance in procurement decisions.
