Main alloy of anodized aluminum circle & disc：3003Quick Quote

The typical application of anodized Aluminum circle & disc is rice cooker liner. In addition, anodized aluminum circle & disc is widely used in many industries such as advanced color cookers.

After anodizing, the hardness and corrosion resistance of anodized aluminum circle & disc will increase. As aluminum alloy is easy to be oxidized by external factors without surface treatment, anodized surface treatment can improve corrosion resistance, enhance wear resistance and hardness, and protect metal surface.

What are good aluminum circle & disc blanks?

In order to ensure the quality of aluminum circle & disc, Aiboer Technology sets up special quality inspection posts during the production process.

1. The surface of aluminum circle & disc

The aluminum circle & disc with good quality has no deformation, scratches, cracks, yellow spots, etc. And the surface color of high-quality aluminum circle is consistent. If there is color difference, the quality is unqualified.

2. Chemical composition：

The chemical composition of aluminum discs can be detected by professional spectrum analyzer. Then compare with the standard GB/T3880-2012 or ASTM B209. We must ensure that each chemical element is within the range required by the standard.

3. Mechanical properties

The tensile strength and mechanical properties of aluminum rounds are tested by a tensile testing machine to ensure that the tensile strength and elongation meet the standards. If the mechanical properties are not up to the standard, it is easy to break during the stamping and spinning process. It will waste a lot of time and material costs in production.

The tensile strength of aluminum circle & disc 1050-O is generally 60Mpa to 100Mpa; Elongation is about 35%. The tensile strength of aluminum circle & disc 1050 H12 is generally about 100Mpa, and the elongation is about 10%.

4. Particle size test

Different manufacturers have different requirements for grain size. According to international standards, most factories control the particle size above Grade II, while some large factories require the particle size to be Grade I. This can ensure that the yield of aluminum circle & disc reaches 98% or even 100% during the production of kitchenware.

What quality problems may be encountered during the use of aluminum discs?

Aluminum discs are widely used in the production of kitchenware, and the following problems are often encountered in the spinning or drawing process. Aiboer Technology tries our best to avoid these problems during the production and transportation process.

Spinning cracking

In the spinning process, due to the presence of sand, impurities, or embedded metal, the aluminum wheel may have crack, edge crack and some other problems. This wastes a lot of time and cost. Such problems often occur in aluminum discs produced from scrap.

Orange peel problem

During spinning, sometimes the surface of the finished pot is not smooth and needs to be polished. The main reason for these problems is that the grain size of aluminum wafer is secondary or the head and tail of materials are not completely removed in the production process of aluminum circle & disc.

Surface oxidation

Although aluminum disc has good rust resistance, if aluminum disc is corroded by rainwater or water during storage or transportation process, its surface is easy to be oxidized. It will affect the beauty of kitchenware. Therefore, the package must be tight and with enough desiccant.

Insufficient weight

The packaging of aluminum round is wooden pallet. Generally, the weight of each pallet is about 1000kg to 1500kg. According to international standards, the weight tolerance is+/- 3 ‰. However, due to the difference in scale and packaging weight, many factories will be short of 5KGS to 10KGS per pallet.

Price quotation for aluminum circle & disc

Generally, the processing price of aluminum rounds varies according to different alloys and widths.

We can process aluminum rounds according to the order quantity, and the price will also decline. We look forward to your consultation.

Price calculation method:

Hot rolled aluminum circle & disc price (yuan/ton)=aluminum ingot price+processing fee+freight

Price quotation of hot rolled aluminum circle & disc

• Aluminum ingot price: normally, it is updated within five days of normal working days, and the update time is at about 10: 30 a.m each day. Three kinds of aluminum prices [the current price, the first three day prices and the first five day prices] will be updated on the same day . We support the cooperation of these three aluminum ingot prices!
• Processing expenses: because the difference of alloy series and the difference of annealing processes, the price of hot rolled aluminum circles is also different. Please contact us for quotation.
• Transportation cost: if you pick it up by yourself, you can arrange vehicles to come to our company for loading and unloading. If the shipment is tax included, our company will handle it and then ship it. Normally, the products will be sent directly to your designated place.

Notice for packaging and transportation of aluminum circle & disc

Packaging of aluminum circle and disc

Aluminum circle & disc are usually packed in a crossing girder way, and the packaging should meet the needs of storage and transportation. The well shaped frame is made of wood, which is composed of two battens at the top and bottom. Generally, the lower height is determined according to the requirements of forklift operation. Make an arc shape corresponding to the roll diameter on the upper beam and fix it with a screw. Generally, the length of the screw should be lower than the surface of the upper beam arc. This is a way to avoid scratching the aluminum disc.

Transportation of aluminum circle and disc

• During the transportation process, a layer of neutral or weak acid material shall be wrapped on the surface of aluminum foil roll and then put into the packing list.
• The lap joint shall be fixed with adhesive tape and padded with soft cushion to protect the end face of aluminum foil roll.
• Put desiccant in the roll and wrap it with plastic cloth. The sealing part of the outermost plastic cloth shall be firmly stuck with adhesive tape, and the remaining parts at both ends of the plastic cloth shall be inserted into the pipe core.
• Finally, put the wrapped aluminum foil roll on the cross and fix it with steel tape, and then stick a case card on the end face of the aluminum foil roll.
• Pay attention to the method of transportation, and handle with care when loading and unloading.
