Cobre

As principais matérias-primas são o sulfeto de cobre e ferro. O cobre tem alta condutividade térmica, boa resistência contra corrosão atmosférica e de ácidos e alta condutividade elétrica, inferior apenas a da prata.

Formatos:

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

  • - Chapas,

  • - Tubos,

  • - Também cortados sob medida.
