Systeemoverzicht: 1050 Aluminium cirkel/schijf (Aluminium ronde blanco)

De 1050 Aluminium cirkel (also known as Aluminum Disc) is a circular blank made from commercially pure aluminum (1000 serie). 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, verlichtingsarmaturen, en verpakking.

1. Core Identification: Samenstelling, Woedeaanval, en Specificaties

  1. Chemische samenstelling & Normen
    • Primary Standards: GB/T 3190, ASTM B209, IN 573.
    • Kerncompositie: Aluminium (Al) content not less than 99.5%, with very low levels of impurities such as Silicon (En) and Iron (Fe). No alloying elements are intentionally added.
    • Belangrijkste kenmerk: High purity with strict control over total impurities, ensuring excellent electrical conductivity, thermische geleidbaarheid, en corrosiebestendigheid.
  2. Common Supply Tempers
    • O humeur (Gegloeid): Soft material with superior ductility, ideal for deep drawing and stamping​ processes (bijv., pot stretching).
    • H14 / H18 Temp (Door spanning gehard): Cold-worked for increased strength and hardness, with reduced elongation. Suitable for shallow forming or parts requiring higher rigidity.
  3. Typical Specification Range
    • Dikte: 0.3 mm – 10.0 mm
    • Diameter: 100 mm – 1650 mm (Custom sizes available)
    • Oppervlakteafwerking: Helder, molen (satin), gecoat, enz.

3. Primary Production Process

Aluminum Ingot → Melting & Continuous Casting into Slab → Hot/Cold Rolling to Gauge → Continuous Annealing (to control temper) → Slitting/Cross Cutting → CNC Punching/Shearing into Circles → Deburring, Schoonmaak, Surface Treatment → Inspection & Verpakking.

4. Typische toepassingen

  • Kookgerei & Gebruiksvoorwerpen: Non-stick cookware body/base, potten, bakplaten, kettle base, deksels.
  • Verlichting & Elektrisch: LED-lampreflectoren, tinten, substraten voor koellichamen, condensator behuizingen.
  • Verpakking & Canisters: Food cans, ointment boxes, cosmetic cases, small chemical pails.
  • Decoratief & Hardware: Badges, naamplaatjes, instrumentenpanelen, general structural components.

5. Comparison with Common Similar Alloys

Legering Al Content Core Differences & Kenmerken Typical Application Preference
1050​ ≥99,5% Best balance of purity and formability.​ Strict impurity control, excellent all-around workability, kosteneffectief. Various deep-drawn cookware, keukengerei, algemene hardware.
1060​ ≥99,6% Iets hogere zuiverheid dan 1050, offering better electrical/thermal conductivity at a slightly higher cost. Elektrische componenten, heat sinks where higher conductivity is critical.
3003​ ~98% Aluminum-Manganese alloy.​ Significantly higher strength and corrosion resistance than 1050. Can be strengthened by cold working. Chemische containers, ducts, architectural trim requiring higher strength.
