3104 Cercles en aluminium: L'innovateur & Référence de performances pour l'emboutissage profond
—— High Elongation · Superior Corrosion Resistance · Precision Customization · Global Trusted Choice
【Product Overview】
Le 3104 Cercle en aluminium, a standout representative of the Al-Mg-Mn alloy series, has set a new benchmark in the metal processing industry, en particulier dans les applications d'emboutissage profond, 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 fonte (to control alloy purity) à laminage à chaud, laminage à froid (for precise thickness and grain refinement), et enfin precision annealing—we optimize the microstructure. This results in exceptional deep drawing performance and unparalleled corrosion resistance. Every 3104 circle features haute précision dimensionnelle, mirror-like surface finish, et stable mechanical properties.
【Technical Specifications】
We offer highly flexible customization to meet diverse industrial needs:
-
Plage de diamètre: Depuis 10mm to 1000mm. We provide professional non-standard customization for ultra-large or ultra-small sizes to match your specific equipment.
-
Plage d'épaisseur: From ultra-light 0.3mm to robust 6.0mm. Thickness tolerance is strictly controlled within $\pm0.02\text{mm}$, exceeding industry standards.
-
Tempéraments disponibles:
-
Ô (Recuit): L'état le plus doux, offering ultimate plasticity and elongation. The top choice for deep drawing and complex forming.
-
H14 / H24 (Durci sous contrainte): Provides a balance of formability and higher strength. Suitable for general stamping.
-
H18 (Plein dur): 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 (Poids %)】
| Élément | Contenu | Impact |
| Silicium (Et) | $\le 0.30\%$ | Enhances strength; kept low to maintain plasticity. |
| Fer (Fe) | $\le 0.7\%$ | Strictly controlled to avoid brittle phases. |
| Cuivre (Cu) | $\le 0.25\%$ | Controlled to balance strength and corrosion resistance. |
| Manganèse (Mn) | $0.8 – 1.3\%$ | Core Element: Improves strength, optimizes grain structure, and enhances deep drawing. |
| Magnésium (Mg) | $0.8 – 1.3\%$ | Core Element: Works with Mn to significantly boost tensile strength and work-hardening capability. |
| Aluminium (Al) | Équilibre | Métal commun. |
【Key Features & Technical Advantages】
-
Superior Deep Drawing Performance
-
High Elongation: With elongation rates exceeding $20\%$, it handles complex deep-cavity forming (par ex., doublures pour autocuiseur) sans craquer.
-
Uniform Deformation: Prevents “rétrécissement” or tearing during tension, significantly reducing scrap rates.
-
Low Work-Hardening Rate: Simplifies the process by reducing the need for intermediate annealing.
-
-
Excellente résistance à la corrosion
-
Stability in Harsh Environments: Highly stable in humid or slightly acidic/alkaline conditions, ce qui le rend idéal pour food-grade contact.
-
Self-Healing Oxide Layer: Enhanced stability against oxidation for long-lasting durability.
-
-
Superior Workability
-
Usinabilité: Supports high-speed cutting with clean cross-sections.
-
Soudabilité: Compatible with TIG, MOI, et soudage par résistance, resulting in high-strength, low-porosity joints.
