# Aços para extrusão a frio

Os aços para extrusão a frio são materiais de engenharia concebidos para serem transformados em componentes por conformação a frio e extrusão. Combinam a ductilidade necessária para uma deformação plástica substancial com a resistência e a tenacidade exigidas em elementos de fixação conformados a frio, peças automóveis e outros componentes de precisão.
