3104 Círculos de Alumínio: O Inovador & Referência de desempenho para estampagem profunda
—— High Elongation · Superior Corrosion Resistance · Precision Customization · Global Trusted Choice
【Product Overview】
O 3104 Círculo de Alumínio, a standout representative of the Al-Mg-Mn alloy series, has set a new benchmark in the metal processing industry, particularmente em aplicações de estampagem profunda, thanks to its unique and balanced chemical composition.
We select high-purity primary aluminum ingots as raw materials. Through a series of rigorous and precise manufacturing processes—from fundição (to control alloy purity) para laminação a quente, laminação a frio (for precise thickness and grain refinement), e finalmente precision annealing—we optimize the microstructure. This results in exceptional deep drawing performance and unparalleled corrosion resistance. Every 3104 circle features alta precisão dimensional, mirror-like surface finish, e stable mechanical properties.
【Technical Specifications】
We offer highly flexible customization to meet diverse industrial needs:
-
Faixa de diâmetro: De 10mm to 1000mm. We provide professional non-standard customization for ultra-large or ultra-small sizes to match your specific equipment.

-
H14 / H24 (Endurecido por tensão): Provides a balance of formability and higher strength. Suitable for general stamping.
-
H18 (Cheio Difícil): For applications requiring maximum tensile and yield strength.
-
-
Surface Finishes:
-
Bright Finish: High gloss, ready for use without additional polishing.
-
Matte Finish: Uniform non-reflective texture, ideal for sandblasting or painting.
-
Anodizing Ready: Specially treated to ensure uniform color and strong film adhesion after anodizing.
-
Coating Substrate: Extremely clean surface for Teflon or other functional coatings.

【Chemical Composition (Peso %)】
| Elemento | Contente | Impacto |
| Silício (E) | $\le 0.30\%$ | Enhances strength; kept low to maintain plasticity. |
| Ferro (Fé) | $\le 0.7\%$ | Strictly controlled to avoid brittle phases. |
| Cobre (Cu) | $\le 0.25\%$ | Controlled to balance strength and corrosion resistance. |
| Manganês (Mn) | $0.8 – 1.3\%$ | Core Element: Improves strength, optimizes grain structure, and enhances deep drawing. |
| Magnésio (mg) | $0.8 – 1.3\%$ | Core Element: Works with Mn to significantly boost tensile strength and work-hardening capability. |
| Alumínio (Al) | Equilíbrio | Metal básico. |
【Key Features & Technical Advantages】
-
Superior Deep Drawing Performance
-
High Elongation: With elongation rates exceeding $20\%$, it handles complex deep-cavity forming (por exemplo, forros de panela de pressão) sem rachar.
-
Uniform Deformation: Prevents “carícias” or tearing during tension, significantly reducing scrap rates.
-
Low Work-Hardening Rate: Simplifies the process by reducing the need for intermediate annealing.
-
-
Excelente resistência à corrosão
-
Stability in Harsh Environments: Highly stable in humid or slightly acidic/alkaline conditions, tornando-o ideal para food-grade contact.
-
Self-Healing Oxide Layer: Enhanced stability against oxidation for long-lasting durability.
-
-
Superior Workability
-
Usinabilidade: Supports high-speed cutting with clean cross-sections.
-
Soldabilidade: Compatible with TIG, MEU, e soldagem por resistência, resulting in high-strength, low-porosity joints.
