Overview of 1070 Aluminum Circle for Reflective Signs

The 1070 aluminum circle is made from high-purity 1070 aluminum as the base material, processed through cold rolling, annealing, cutting, and surface finishing. With an aluminum content of over 99%, it offers excellent corrosion resistance, ductility, and processability, making it highly suitable for manufacturing reflective traffic signs and road indication plates.

After polishing treatment, mirror-finish 1070 aluminum sheets can achieve a reflectivity of 86%-95%, ensuring that reflective signs maximize light reflection in low-light or nighttime conditions-greatly improving visibility and safety on the road.

When anodized, 1070 aluminum circle discs gain additional protection and performance benefits. The anodic oxide layer not only enhances corrosion resistance but also allows adjustment of surface reflection properties, optimizing reflective performance and ensuring longer outdoor service life.

Compared with ordinary aluminum materials, 1070 aluminum wafers guarantee long-term stability, maintaining brightness and shape even under extreme conditions such as high temperatures, rainfall, or strong UV exposure.

Key Features of 1070 Aluminum Circle

1. Excellent Reflective Base Material
High-purity aluminum naturally exhibits strong optical reflectivity. With additional treatments such as polishing or brushing, 1070 aluminum provides a smooth, bright substrate for reflective films, ensuring superior light reflection performance.

2. Outstanding Corrosion Resistance
The pure aluminum surface naturally forms a dense oxide layer, effectively resisting oxidation, humidity, and chemical erosion-keeping outdoor signs rust-free and maintaining reflectivity for years.

3. Lightweight and Strong
Aluminum’s density is only about one-third that of steel, making traffic signs much lighter and easier to install or transport while still retaining excellent strength and rigidity.

4. Superior Workability
1070 aluminum is soft, flexible, and easy to process-ideal for punching, cutting, drilling, and forming into various circular or customized sign shapes.

5. Eco-Friendly and Recyclable
Aluminum is 100% recyclable, aligning with modern environmental protection and sustainability standards.

Applications of 1070 Mirror Aluminum Circles

The 1070 aluminum circle is not only widely used in reflective traffic signs, but also in multiple industrial and commercial fields:

• Traffic Industry: Ideal material for road signs, reflective warning boards, and direction indicators.

• Lighting Industry: Used in lamp reflectors due to its high reflectivity and smooth surface finish.

• Cookware Manufacturing: Polished 1070 aluminum circles are popular for deep-drawn cookware and induction heating discs.

• Architectural Decoration: Suitable for interior panels, ceilings, and reflective decorative elements.

Its versatility and reliability make 1070 aluminum circles one of the most functional materials in modern industrial applications.

Why Choose 1070 Aluminum Circles for Traffic Signs?

1. High Nighttime Visibility
1070 aluminum provides an ideal base for reflective film adhesion and reflection, ensuring signs remain clearly visible at night or in adverse weather conditions.

2. Long-Term Outdoor Durability
With superior corrosion and weather resistance, the signs made from 1070 aluminum maintain their performance and appearance for years, minimizing maintenance costs.

3. Environmental Adaptability
From hot deserts and humid coasts to cold mountainous regions, 1070 aluminum signs retain their shape, color, and reflectivity under all environments.

4. Compliance with Industry Standards
Widely used in national and international road traffic sign production, meeting regulatory performance requirements.
