Import Amorphous And Nano-Crystalline Magnetic Strip — Buy in Bulk from Supplier in China

Beijing Yeke Electronic Materials Co., Ltd. supplies amorphous and nano-crystalline magnetic strip in dimensions spanning 10 by 10 by 200 mm up to 20 by 25 by 100 mm, with custom thicknesses from 20 to 30 micrometres and widths from 2.5 mm to 120 mm. The material exhibits saturation induction of 1.25 T, Curie temperature of 560 degrees Celsius, crystallisation temperature of 510 degrees Celsius, and resistivity of 130 micro-ohm-centimetre. Its hardness reaches 880 kg per square millimetre and density is 7.2 grams per cubic centimetre, with saturate magnetostriction of 2 times 10 to the minus sixth. These strips serve as transformer cores, current transformer cores, ground-fault-interrupter cores, filter and reactor cores, EMC common mode chokes, sensor cores, and saturable reactor cores.

The alloy composition falls within the Fe-based amorphous metal family, with nano-crystalline variants formed through controlled annealing to precipitate nanoscale crystallites within an amorphous matrix. The supplier offers three annealing conditions: transverse field, no field, and longitudinal field, each yielding distinct magnetic properties. Initial permeability exceeds 3 times 10 to the fourth for transverse field, 8 times 10 to the fourth for no field, and 1 times 10 to the fourth for longitudinal field annealing. Maximum permeability ranges from above 5 times 10 to the fourth to above 50 times 10 to the fourth depending on annealing method. Remanence sits at 0.85 T and coercivity remains low across all variants, with core loss equivalent to one-fifth to one-third that of silicon steel. Standard industry grades for this material class typically align with IEC 60404-8 and ASTM A799 specifications for amorphous strip.

Operating frequency ranges from 50 Hz to 10 kHz for power-frequency distribution transformers and up to 50 kHz for high-power switching power supply reactors. Buyers span electric power equipment manufacturers, renewable energy inverter producers, automotive electronics suppliers, and industrial control system integrators. The strips replace silicon steel in weight-sensitive or loss-critical applications. Packaging and minimum order quantities are not stated in the source data and should be confirmed directly with Beijing Yeke Electronic Materials Co., Ltd. Lead times and preferred Incoterms also require direct enquiry, as response rate and average response time are both currently recorded at zero.

Beijing Yeke Electronic Materials Co., Ltd. is located at 3-4 Zong Er Road, Shunyi District, Beijing 101309, China. The company holds an imported supplier tier designation and a harbor trust tier classification on the platform. Its response rate is recorded at 0.00 percent with zero average response hours, indicating limited or no engagement through platform messaging channels. Potential buyers should note this communication gap and plan to reach out through alternative contact methods if platform messaging proves unresponsive.

The supplier's listing focuses on technical performance data rather than corporate history, production capacity, or client references. No information is provided about year of establishment, employee count, annual revenue, factory size, or export markets served. The product range centres on amorphous and nano-crystalline magnetic strip with custom dimension capabilities. Buyers should verify manufacturing qualifications, quality management system certifications, and sample availability before committing to volume orders.
