Folhas para brasagem

 Tiras e cortes de folhas de brasagem de prata e fósforo-cobre. Nossas folhas de brasagem de prata e fósforo-cobre possuem uma superfície de alta qualidade, com tolerâncias de espessura abaixo dos requisitos padrões. 

O uso de folha de prata para a união de carbonetos de tungstênio com aço é bastante comum. Especialmente as ligas contendo manganês e níquel são muito populares devido às suas propriedades positivas de molhabilidade e resistência, por exemplo, na indústria de lâminas de serra. 

Muitos de nossos clientes aproveitam as vantagens da A 338 F, uma folha contendo níquel e manganês conforme a norma ISO 3677. Essa folha possui propriedades comparáveis em termos de faixa de fusão, resistência e molhabilidade, combinadas com um menor teor de prata. É uma alternativa comum à A 324 F padrão. 

A Fontargen Brazing está envolvida em diversos projetos de P&D em todo o mundo, além de parcerias com empresas da indústria de ferramentas. Oferecemos o suporte técnico essencial para desenvolver uma otimização do processo técnico em colaboração com o cliente. Compartilhamos nosso conhecimento na seleção do material de adição de solda perfeito e damos suporte a especialistas em brasagem com a aplicação ideal. 

A Fontargen Brazing fornece as seguintes ligas padrão em tamanhos personalizados:
