aluminum circle 5052
Green House Aluminum
76069100
5052 aluminum circle belongs to Al-Mg-Si aluminum alloy. The main alloying element of 5052 is magnesium, which has good formability, corrosion resistance, weldability and medium strength.It is mainly used in lamps, kitchenware, electronic and electrical enclosures, traffic signs, etc
We also can produce laser cutting 5052 aluminum circles in up to 5mm thickness and over 1meter large diameters.
Aluminum 5052 is not a heat-treatable alloy (like the common 6061). Instead, it is strain-hardened or work-hardened. Its primary alloying elements are:
Magnesium (Mg): ~2.5% - This is the main alloying element. It significantly increases strength, especially after work hardening, and provides excellent corrosion resistance.
Chromium (Cr): ~0.25% - Adds to corrosion resistance and controls grain structure.
This composition makes AA5052 one of the strongest non-heat-treatable aluminum alloys.
The combination of the 5052 alloy and the circle form factor gives it a unique set of properties:
Excellent Corrosion Resistance: Particularly against saltwater and marine atmospheres. This is far superior to the 1xxx series (like 1100) and most 3xxx series alloys.
High Fatigue Strength: It can withstand repeated loading and stress without failing, making it ideal for parts that are in motion or under vibration.
Good Formability: It is highly ductile and can undergo significant shaping without cracking. This is crucial for its primary use in deep drawing and spinning.
Moderately High Strength: While not as strong as 6061-T6, its strength, especially in the H32 or H34 temper, is very good for a non-heat-treatable alloy.
Excellent Surface Finish: It takes very well to anodizing, painting, and other surface treatments, resulting in a beautiful, durable finish.
Good Weldability: It can be readily welded using conventional methods, though its strength in the weld zone will be reduced.
Non-Toxic & Odorless: This makes it safe for contact with food, which is a critical requirement for cookware.
The "temper" indicates the degree of hardening the material has undergone.
O (Annealed): The softest state. Maximum formability and ductility, but lowest strength. Used for the most severe deep-drawing operations.
H32: Strain-hardened and stabilized. This is a very common temper. It offers a good balance of strength and formability.
H34: Strain-hardened and stabilized to a greater degree than H32. Higher strength, good formability.
H36 / H38: Even higher strength levels, used for applications where formability is less critical but rigidity is important.
H32 and H34 are the most widely used tempers for aluminum circles.
This is where the "circle" shape becomes essential. 5052 circles are the raw material for a vast range of spun and drawn products:
Cookware: Pots, pans, fry pans, lids, pressure cooker bodies. Its formability and surface quality are perfect for this.
Traffic Signs: Road signs, street name signs. The circles are stamped and then painted with reflective sheeting. The H3x tempers provide the necessary rigidity.
LED Lighting: Housing and reflectors for LED lights. It dissipates heat well and provides a great surface for reflective finishes.
Utensils & Kitchenware: Rice cooker liners, mixing bowls, travel mugs.
Electrical Enclosures: Various housings and chassis that require shielding and durability.
Marine Components: Parts exposed to saltwater environments, such as boat fittings and trim.
Decorative Items: Lampshades, trophies, awards, and other decorative metal items.
vs. 1100 / 1050: 5052 is significantly stronger and has much better corrosion resistance, especially in harsh environments. 1100 is softer and more conductive but too weak for structural applications.
vs. 3003: 3003 is also a work-hardenable alloy (with Manganese). 5052 is stronger and has superior marine corrosion resistance. 3003 is often chosen when slightly better formability is needed over strength.
vs. 6061: 6061 is heat-treatable and can achieve much higher strengths (T6 temper). However, 5052 has far superior formability and fatigue strength. You would choose 5052 for deep drawing and 6061 for machining or structural frames.

In conclusion, the aluminum circle 5052 is a fundamental industrial material prized for its exceptional combination of formability, strength, and corrosion resistance. Its pre-cut circular form makes it the efficient and logical choice for manufacturing a wide array of cylindrical and domed products we use every day.
Here are its most common applications:
Pots and Pans: It's the perfect material for the main body of cookware. It's strong, doesn't rust, and can be easily shaped into pots, frying pans, and lids.
Rice Cooker Inserts: The inner pot that holds the rice is often made from this.
Mixing Bowls & Travel Mugs: It's easily formed into perfect round shapes.
Road Signs: The blank circles are stamped into stop signs, speed limit signs, etc. The material is strong enough to hold its shape and takes paint and reflective sheeting very well.
Housings and Reflectors: It's used for the base and the reflective "cup" inside LED bulbs and fixtures. It helps dissipate heat and can be shaped to direct the light.
Speaker Grills & Covers: Its good formability allows it to be pressed into decorative and protective grills.
Shielding Cans: It can be formed into small casings that protect sensitive electronic components.
In short: If a product is round, bowl-shaped, or cylindrical and needs to be strong, lightweight, and corrosion-resistant, there's a good chance it started as an aluminum circle 5052.
Here are the most common ways they are packed:
Wooden Crates (Strongest Protection)
Circles are stacked on a wooden base, separated by layers of paper or plastic.
A wooden frame is built around them, and sometimes fully enclosed.
Used for: Long-distance travel, especially overseas (sea freight).
Wooden Pallets (Standard & Popular)
Circles are stacked on a wooden pallet.
They are tightly wrapped in strong plastic stretch film to hold them together and keep out moisture and dust.
Used for: Most general orders and truck transport.
Simple Bags (For Small/Short Trips)
A small number of circles are put into a clear plastic bag.
Used for: Small quantity orders or local delivery where damage is less likely.
