Visão geral do sistema: 1050 Círculo/disco de alumínio (Placa redonda de alumínio)

O 1050 Círculo de Alumínio (also known as Aluminum Disc) is a circular blank made from commercially pure aluminum (1000 Series). With high aluminum content (≥99,5%), it offers excellent formability and surface treatment capabilities, making it an essential raw material for deep-drawn products like cookware, luminárias, e embalagem.

  1. Composição Química & Padrões
    • Primary Standards: GB/T 3190, ASTM B209, EM 573.
    • Composição Central: Alumínio (Al) content not less than 99.5%, with very low levels of impurities such as Silicon (E) and Iron (Fé). No alloying elements are intentionally added.
    • Recurso principal: High purity with strict control over total impurities, ensuring excellent electrical conductivity, condutividade térmica, e resistência à corrosão.
  2. Common Supply Tempers
    • Ó temperamento (Recozido): Soft material with superior ductility, ideal for deep drawing and stamping​ processes (por exemplo, pot stretching).
    • H14 / Temperamento H18 (Endurecido por tensão): Cold-worked for increased strength and hardness, with reduced elongation. Suitable for shallow forming or parts requiring higher rigidity.
  3. Typical Specification Range
    • Grossura: 0.3 milímetros – 10.0 milímetros
    • Diâmetro: 100 milímetros – 1650 milímetros (Custom sizes available)
    • Acabamento de superfície: Brilhante, moinho (satin), revestido, etc..
