A liga de alta temperatura GH3044 \u00e9 uma liga de alta temperatura de deforma\u00e7\u00e3o refor\u00e7ada com solu\u00e7\u00e3o s\u00f3lida \u00e0 base de Ni-Cr com uma temperatura de servi\u00e7o abaixo de 900 \u2103. A liga cont\u00e9m uma grande quantidade de tungst\u00e9nio e uma pequena quantidade de alum\u00ednio e tit\u00e2nio. A liga tem alta plasticidade e resist\u00eancia t\u00e9rmica m\u00e9dia, e tem excelente resist\u00eancia \u00e0 oxida\u00e7\u00e3o e bom desempenho do processo de estampagem e soldagem. Adequada para o fabrico de pe\u00e7as da c\u00e2mara de combust\u00e3o principal e da c\u00e2mara de combust\u00e3o do p\u00f3s-combustor de um motor aeron\u00e1utico que trabalhe a menos de 900\u00b0C durante muito tempo, bem como ecr\u00e3s de isolamento t\u00e9rmico, l\u00e2minas de guia, etc. Os principais produtos fornecidos s\u00e3o placas, tiras, sedas e an\u00e9is.<\/p>\n
