আমি. ভূমিকা: কেন 5052 Aluminum Circles Are Better Suited for Strength-Priority Applications

The application scope of aluminum circles has expanded significantly into areas such as automotive components and pressure cookware, where performance requirements vary widely and strength-priority scenarios are increasingly common.

Traditional alloys such as 1060 এবং 3003 aluminum circles often fail to meet mechanical strength requirements in these applications. বিপরীতে, 5052 অ্যালুমিনিয়াম বৃত্ত, with their combination of high strength and corrosion resistance, effectively fill this gap. Selecting the appropriate alloy is directly related to operational safety, এবং high specific strength of 5052 aligns well with modern lightweight design trends.

III. Core Process Analysis: How to Produce Qualified 5052 অ্যালুমিনিয়াম চেনাশোনা

(Key Parameters Included)

High-quality material alone is insufficient without strict process control. The standard production route for 5052 aluminum circles includes:

Raw material → Melting & casting → Homogenization annealing → Hot rolling → Cold rolling → Circle cutting → Final annealing

1. Raw Material and Casting: Establishing the Strength Baseline

• Material standard: 5052 aluminum ingots compliant with GB/T 3190-2022
• Impurity limits: ফে ≤ 0.4%, এবং ≤ 0.25%, Cu ≤ 0.1%
• Magnesium control: ±0.05% tolerance to ensure stable strength
• গলে যাওয়া তাপমাত্রা: 730-760 °সে
• Refining: Argon-nitrogen gas refining for 15–20 minutes; holding for 20–30 minutes
• Casting speed: 80–120 mm/min with matched cooling to ensure uniform grain structure

2. Homogenization Annealing: Eliminating Structural Defects

• উদ্দেশ্য: Reduce segregation, refine grains, and relieve internal stress
• পরামিতি: 450–480 °C, holding for 6–8 hours
• গরম করার হার: 50–80 °C/h
• কুলিং: Furnace cooling or air cooling to room temperature

Insufficient homogenization leads to compositional non-uniformity, while excessive treatment causes grain coarsening and strength loss.

3. Hot Rolling and Cold Rolling: Strength Enhancement Through Deformation

• Hot rolling start temperature: 400-450 °সে
• Finish temperature: ≥300 °C
• Total hot reduction: 70-80%
• Cold rolling reduction: 60-80%
• ঘূর্ণায়মান গতি: 50–150 m/min
• Roll cooling water temperature: 20–30 °C

Cold rolling increases strength via work hardening, while controlled hot rolling refines grain structure.

4. Final Annealing and Circle Cutting: The Last Quality Gate

• অ্যানিলিং তাপমাত্রা: 300-350 °সে
• সময় ধরে রাখা: 2–4 hours
  • চাপ রান্নার পাত্র: 300–320 °C, 2–3 h
  • Automotive fuel tanks: 330-350 °সে, 3–4 h
• বায়ুমণ্ডল: Nitrogen or argon protection
• কাটিং প্যারামিটার: 100–200 rpm, feed 0.1–0.3 mm/rev
• সহনশীলতা: Diameter ±0.2 mm; flatness ≤0.5 mm/m
