Materiais magnéticos são materiais funcionais fundamentais da indústria eletrônica. Tão importantes peças de materiais magnéticos, materiais de ferrita difícil jogar um heavyrole na indústria eletrônica, indústria de informação eletrônica, indústria automóvel, motocicleta indústria etc. Entretanto, são também amplamente utilizados no tratamento médico, mineração e metalurgia, automação industrial, indústria de energia de óleo e civis. imã de ferrite, ímãs de ferrite, ímã ligado da ferrite, imã de ferrite de bário, imã de ferrite duro, imã de ferrite sinterizada, ímã de injeção ligado da ferrite
Nossos produtos principais inclui: ferrite duro arco ou segmento, ímans, ímãs retangulares, ferrita poder etc. Que têm as seguintes vantagens: força coercitiva elevada, alta resistência elétrica, estabilidade de longa data e preço econômico. Enquanto isso, nós podemos manufaturar novas ferramentas de acordo com a demanda dos clientes. imã de ferrite, ímãs de ferrite
