Custom Blank 1mm 3003 Aluminum Disc – Any Diameter: The Ultimate Flexible Component Solution

The Custom Blank 1mm 3003 Aluminum Disc embodies these principles, offering engineers and designers a foundational component that can be tailored to virtually any diameter requirement. This product bridges the gap between off-the-shelf limitations and fully custom fabrication, providing a cost-effective, high-performance starting point for countless applications.

1. Core Material Advantage: Why Choose 1mm 3003 Aluminum Discs?

3003 aluminum alloy is an aluminum-manganese alloy renowned for its excellent formability, good weldability, and superior corrosion resistance. The 1mm thickness offers an ideal balance: providing sufficient structural rigidity and durability while remaining lightweight and suitable for secondary processing such as stamping, bending, and deep drawing.

Key Characteristics Include:

Excellent Corrosion Resistance: Naturally resistant to atmosphere, water, and many chemicals.
Good Mechanical Properties: Offers a good balance of strength and ductility in the H14 half-hard temper.
High Machinability: Easy to cut, drill, bend, and form.
Excellent Thermal & Electrical Conductivity: Suitable for applications requiring heat dissipation or electromagnetic shielding.

Table 1: Typical Mechanical Properties of 1mm Thick 3003 Aluminum (H14 Temper)

Property	Parameter Value	Description
Tensile Strength	140-180 MPa	Provides good structural integrity
Yield Strength	115-145 MPa	Suitable for moderate load-bearing
Elongation	8-14%	Indicates good formability potential
Hardness (Brinell)	40-60 HB	Balances machinability and wear resistance

2. Precision Manufacturing: How is “Any Diameter” Customization Achieved?

We utilize advanced manufacturing technologies to ensure each disc meets stringent dimensional and quality standards.

Precision Shearing & Blanking: Ideal for medium/small diameters and high-volume production, offering high efficiency and excellent dimensional consistency.
CNC Laser Cutting: Suitable for any diameter (typically from a few millimeters to several meters), complex contours, or small-batch prototyping. Offers high cutting precision, a minimal heat-affected zone, and no tool wear.
Quality Control: Each batch undergoes rigorous dimensional inspection (using calipers, projectors, or CMMs) and surface checks to ensure compliance with drawing tolerances.

Nominal Diameter Range (mm)	Standard Tolerance (±mm)	Precision Tolerance (±mm)
≤ 100	0.15	0.05
101 – 300	0.20	0.10
301 – 600	0.30	0.15
> 600	0.50 or as agreed	0.25 or as agreed

5. Selection Guide: How to Place an Order Correctly?

To ensure you receive the most suitable product, please clarify the following information when inquiring or placing an order:

Material & Temper: e.g., “3003 H14”.
Dimensions: Thickness (1mm), Diameter (provide drawings or clear dimensions and tolerances).
Quantity: Prototype quantity or production volume.
Surface Requirements: If specific treatment is needed.
Special Requirements: Such as packaging method, material certification, etc.
End Use: Informing us of your application allows for more professional advice.

6. Frequently Asked Questions (FAQ)

Q1: What is the minimum and maximum diameter you can produce?

A: Theoretically, we can produce any diameter from the smallest size cuttable from the raw material (typically ~10mm) up to the maximum sheet width (currently over 1500mm). For extremely small diameters (<10mm), stamping or other processes may be recommended. For extremely large diameters, feasibility confirmation is needed based on specific size and equipment capability.

Q2: What is the edge condition? Is secondary processing needed?

A: The edges of discs we deliver are typically in the as-cut condition (laser or sheared) and may have minor burrs. For most applications, this edge condition is acceptable for direct use. If your application requires very smooth edges (e.g., for sealing or safe handling), please specify in advance, and we can provide deburring service.

Q3: Can 1mm thick 3003 aluminum discs be bent or deep drawn?

A: Yes. 3003 aluminum alloy inherently has good formability. In the H14 temper, 1mm thickness is suitable for bending to certain angles (recommended minimum inside bend radius is about 1-1.5 times the thickness) and moderate deep drawing. For complex deep drawing, O-temper (soft) material may be required, which we can also supply.

Q4: What is the minimum order quantity (MOQ)?

A: We are very flexible. For laser-cut custom discs, there is typically no strict MOQ; we can produce even single-piece prototypes, though the unit price will be correspondingly higher. For large-volume orders, prices are more competitive. Please discuss your specific needs with us.

Q5: What file formats can you accept for production?

A: We accept various formats, including common engineering drawing formats like DWG, DXF, PDF, or STEP. Please ensure key dimensions, tolerances, and material requirements are clearly marked on the drawings. If you only have sketches or ideas, our engineers can also assist you in finalizing the design.

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.
