Ligas

Trabalhamos com ligas resistentes à alta temperatura, corrosão e abrasão, que permitem um melhor desempenho e maior vida útil das peças fundidas.

A escolha da liga mais apropriada, aliada à sua qualidade metalúrgica e ao correto projeto, é fundamental para que a peça tenha a performance esperada.

A Machroterm é especialista em ligas e está pronta para orientá-lo, responsabilizando-se pelo processo de produção do projeto à entrega. Atendemos todo o mercado nacional e internacional.
