Alumínio

Tem como matéria-prima a bauxita, mineral com cerca de 60% de óxido de alumínio. Tem boa resistência à corrosão atmosférica e à vários produtos químicos e tem uma boa condutividade elétrica.

Formatos:

  • - Barras (retangulares, redondas, quadradas, sextavadas)

  • - Chapas,

  • - Tubos,

  • - Bobinas,

  • - Também cortados sob medida.
