What Is 1070 Aluminum Circle?
The 1070 aluminum circle is a flat, round-shaped aluminum blank. It is cut or stamped from aluminum sheet or coil. The number “1070” refers to the alloy designation. This alloy has a very high aluminum content – at least 99.7%. The remaining fraction includes trace elements like iron, silicon, and copper.
Because of its high purity, 1070 aluminum is extremely soft and ductile. It stretches and forms easily without cracking. This makes it ideal for deep drawing and spinning into finished products. It is also non-toxic and food-safe, which is important for cookware and food packaging.
Key fact: 1070 aluminum circle is one of the most common grades used in the production of non-stick cooking pots, pans, and pressure cookers worldwide.

Applications of 1070 Aluminum Circle
The 1070 aluminum circle has excellent formability. It is used in many industries. Below are the most common applications:
Cookware and Kitchen Products
This is the largest application. Factories use 1070 aluminum circles to produce pots, pans, woks, pressure cookers, and frying pans. The material draws easily without tearing. It heats evenly and is safe for food contact. Non-stick coatings bond well to the surface.
Road Signs and Traffic Signs
Thin 1070 aluminum circles are cut and formed into reflective road signs. The material is lightweight and resistant to corrosion. Signs last for many years outdoors without rusting.
Lamp Covers and LED Lighting
1070 aluminum circles are spun or pressed into round lamp shades and LED housing covers. The high thermal conductivity helps dissipate heat. The surface can be anodized or powder-coated for a decorative finish.
Electrical Transformers
High-purity aluminum has excellent electrical conductivity. 1070 aluminum is used to make transformer discs and winding components. It is a cost-effective alternative to copper in some applications.
Capacitor Shells and Electronic Parts
The soft temper and high ductility make 1070 suitable for spinning capacitor housings and other small electronic components. Dimensional accuracy is critical in these parts.
Other Applications
- Milk churns and dairy equipment
- Food packaging lids and caps
- Chemical processing equipment
- Decorative discs and medallions
- Filter end caps

1070 vs Other Aluminum Circle Grades
Customers often ask about the difference between 1070 and other aluminum grades. Here is a simple comparison:
| Grade | Al Content | Strength | Formability | Best Use |
|---|---|---|---|---|
| 1050 | ≥99.5% | Low | Excellent | General cookware, signs |
| 1060 | ≥99.6% | Low | Excellent | Cookware, electrical |
| 1070 | ≥99.7% | Low | Excellent | High-purity cookware, capacitors |
| 1100 | ≥99.0% | Low-Medium | Very Good | General purpose |
| 3003 | ~97.5% | Medium | Good | Pressure vessels, containers |
| 5052 | ~96.5% | Medium-High | Good | Marine, structural parts |
1070 offers the highest purity among common aluminum circle grades. When customers need the best formability and corrosion resistance, 1070 is the right choice.
1070 Aluminum Circle Price
The price of 1070 aluminum circles depends on several factors. These include the current aluminum ingot price on the London Metal Exchange (LME), the thickness and diameter of the circles, the temper required, the surface treatment, and the order quantity.
Generally, larger orders receive lower prices per kilogram. The base price follows the LME aluminum price plus a processing premium. As a factory, we offer very competitive rates because we control our own production.
Please contact us for a custom quotation. We respond within 24 hours. We will ask about your required size, quantity, and delivery address to give you an accurate price.
Tip: Ordering in larger quantities (5 tons or more) usually reduces the unit price significantly. Ask us about bulk pricing and long-term supply agreements.

Frequently Asked Questions
What is the difference between 1060 and 1070 aluminum circle?
Both are high-purity aluminum circles. The main difference is the aluminum content. 1060 contains at least 99.6% aluminum. 1070 contains at least 99.7% aluminum. 1070 has slightly better corrosion resistance and electrical conductivity. Both grades are excellent for deep drawing.
What temper is best for deep drawing?
The O temper (annealed) is the best choice for deep drawing. It gives maximum softness and elongation. This prevents cracking during forming. H tempers are harder and are used when some strength is needed after forming.
Can you supply custom diameters?
Yes. We can produce circles in any diameter from 100 mm to 1600 mm. We accept non-standard sizes. Please send us your drawing or specifications.
What is the minimum order quantity?
Our standard MOQ is 500 kg. For very common sizes, we can sometimes accept smaller trial orders. Contact us to discuss your needs.
Do you provide material test reports?
Yes. We provide a mill test report (MTR) with every shipment. The report shows chemical composition, mechanical properties, and dimensions. Third-party inspection by SGS or Bureau Veritas is also available on request.
