3. Why Choose 3003 Alloy as the Core Material?

  1. Food-Grade Safety: 3003 is a manganese-based alloy with no risk of heavy metal leaching.

  2. Superior Deep Drawing: Our 3003-O discs exhibit excellent ductility, preventing bottom cracking during high-speed stamping.

  3. Uniform Heat Distribution: Aluminum‘s thermal conductivity prevents “hot spots,” ensuring consistent cooking results.


4. Supply Chain & Logistics Excellence

We understand that material protection during sea freight is crucial to preventing oxidation and scratches.

● Table C: Packaging & Logistics Standards

Item Standard Specification Protection Goal
Core Packing Export-grade wooden pallets (Fumigated) Structural stability
Layering Paper Interleaved / PE Film Prevents surface friction/scratches
Barrier Desiccants + PE Moisture-proof wrapping Prevents oxidation in humid sea air
Movers 20ft Container (approx. 20-25 Tons) Optimized shipping cost
Lead Time 20 – 30 Days Reliable production scheduling

5. Application Scenarios & Success Stories

Typical Processing Flow:

  1. Blanking: Precision punching into discs.

  2. Drawing/Spinning: Forming the pot or kettle body.

  3. Trimming & Polishing: Optimizing the edge feel.

  4. Surface Treatment: Applying non-stick layers or anodizing.


6. FAQ: Frequently Asked Questions

Q1: What is the difference between 3003 and 1060 discs?

A: 3003 has higher hardness and corrosion resistance due to Manganese, making it the standard for coated cookware. 1060 is softer and suited for simple utility items.

Q2: Can I get a custom diameter (e.g., 1005mm)?

A: Yes. We specialize in custom blanking sizes to minimize your scrap rate.

Q3: Are samples available?

A: We provide 3-5 free sample discs for your engineering team to verify drawing performance.

Properties of the aluminum circle:

Aluminum circle is suitable for many markets, including cookware, automotive and lighting industries, etc., thanks to good product characteristics:

  • Low anisotropy, which facilitates deep drawing
  • Strong mechanical properties
  • High and homogeneous heat diffusion
  • Ability to be enameled, covered by PTFE (or others), anodized
  • Good reflectivity
  • High strength-to-weight ratio
  • Durability and resistance to corrosion

Aluminum Circles Process

Ingot/Master Alloys — Melting Furnace – Holding Furnace — D.C. Caster — Slab —- Scalper — Hot Rolling Mill – Cold Rolling Mill – Punching – Annealing Furnace — Final Inspection – Packing — Delivery

  • Prepare the master alloys
  • Melting furnace: put the alloys into the melting furnace
  • D.C.cast aluminum ingot: To make the mother ingot
  • Mill the aluminum ingot: to make the surface and side smooth
  • Heating furnace
  • Hot rolling mill: made the mother coil
  • Colding rolling mill: the mother coil was rolled as the thickness you want to buy
  • Punching process: become the size what you want
  • Annealing furnace: change the temper
  • Final inspection
  • Packing: wooden case or wooden pallet
  • Delivery

Quality Control

Assurance Below inspection will be done in the production.

  • a. ray detection—RT;
  • b. ultrasonic testing—UT;
  • c. Magnetic Particle Testing-MT;
  • d. penetration testing-PT;
  • e. eddy current flaw detection-ET

1) Be free from Oil Stain, Dent, Inclusion, Scratches, Stain, Oxide Discoloration, Breaks, Corrosion, Roll Marks, Dirt Streaks, and other defects which will interfere with use.

2) Surface without black line, clean-cut, periodic stain, roller printing defects, such as other gko internal Control standards.

Aluminum discs packing:

Aluminum circles can be packed by export standards, covering with brown paper and plastic film. Finally, the Aluminium Round is fixed on a wooden pallet/wooden case.

  • Put the driers side the aluminum circle, keep the products dry and clean.
  • Use clean plastic paper, pack the aluminium circle, keep good sealing.
  • Use the snakeskin paper, pack the surface of the plastic paper, keep good sealing.
  • Next, there are two ways of packaging: One way is wooden pallet packaging, using the crusty paper packing the surface; Another way is wooden case packaging, using the wooden case packing the surface.
  • Finally, lay the steel belt on the wooden box’s surface, keeping the wooden box fastness and secure.

Aluminum circle of Henan Huawei Aluminum. meet the export standard. Plastic film and brown paper can be covered at customers’ needs. What’s more, a wooden case or wooden pallet is adopted to protect products from damage during delivery. There are two kinds of packaging, which are eye to wall or eye to the sky. Customers can choose either of them for their convenience. Generally speaking, there are 2 tons in one package, and loading 18-22 tons in 1×20′ container, and 20-24 tons in 1×40′ container.
