Anodized Aluminum Disc Circle Overview
Anodized Aluminum Disc Circle is a protective measure for aluminum discs. The aluminum wafer is placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode, and under specific conditions and applied current, electrolysis is performed to form aluminum circle coating–aluminum oxide thin layer on its surface, So as to achieve the effect of anti-corrosion and anti-oxidation.
Effect Of Anodizing On Circle Disc Aluminum
Generally, the thickness of the anodized protective film of the aluminum wafer is 5-20 microns, and the harder anodized film can reach 60-200 microns. The anodizing treatment increases the corrosion resistance of the aluminum wafer, and at the same time can improve the hardness and wear resistance of the aluminum wafer; the melting point of the hard-anodized film is as high as 2320K, which has better heat resistance than before the anodization. The promotion.
Process Flow Of Anodized Aluminum CIrcles Products
Aluminum workpiece → polished → upper hanger → degreasing → water washing → alkali etching → water washing → light-emitting → water washing → anodizing → water washing → deionized water washing → dyeing or electrolytic coloring → water washing → deionized water washing → sealing → water washing → lower hanger
Aluminum Circle Round Features
(1) Good processing performance: The anodized aluminum wafer has a good decorative feeling, moderate hardness, and continuous high-speed stamping. It has good plasticity and is convenient to be directly processed into products without complicated surface treatment, which can greatly shorten the product production cycle and reduce product production costs.
(2) Good corrosion resistance: Alumina film (3μm) with a standard thickness after anodization can be used indoors without discoloration, corrosion, oxidation, and rust for a long time. The thickened aluminum oxide film (10μm) anodized aluminum sheet can be used outdoors and can be exposed to sunlight for a long time without fading.
(3) Strong metal texture: the aluminum discs after anodizing treatment have high hardness, which can reach the gem level and have good scratch resistance. Even if the surface is not covered by paint, the metal color of the aluminum plate can be well preserved, highlighting the modern metallic feel, and increasing the texture of the product in appearance.
(4) High fire resistance: pure metal aluminum products without any chemical substances on the surface, even if it does not burn at a high temperature of 600 degrees, it will not produce toxic and harmful gases, which fully meets the requirements of fire protection and environmental protection.
(5) Strong stain resistance: no fingerprints and stains left on the touch, easy to clean, and no corrosion spots.
(6) Excellent insulation, withstand breakdown voltage up to 2000V
Aluminum Circle Disc Plate Application Scenarios：
Because of the excellent chemical and physical properties of the anodized wafer, the high-quality aluminum circle can be widely used in all aspects of life. It’s suitable for kitchen supplies, such as cooking pots, utensils, cookware, caution traffic sign, pan, usw.
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.
