What are the production processes of aluminum discs?

Stamping: Aluminum coils are punched into round sheets using a punching machine anda round die,which is suitable for efficient and low-cost mass production.

Shearing: Use shearing machine to cut aluminum plate into circular sheets, which ishighly flexibleand suitable for customized production.

Laser Cutting: Using laser cutting machine to accurately cut preset graphics, withhigh precisionand good edge quality, suitable for cutting complex shapes.

Water Jet Cutting: Cutting with high-pressure water flow mixed with abrasives, noheat-affectedzone, high cutting accuracy, suitable for cutting thick aviation plates.

Milling: Use a milling machine to partially mill the aluminum plate to form acircular sheet withhigh precision.

Spinning: Fix the aluminum disc on the spinning machine and gradually form itthrough the spinningtool. It is suitable for the production of lamp reflectors, kitchen utensils, and gas cylinderbottoms.

Punching: Use a punching machine to punch out multiple small discs on the aluminumplate. It isefficient and suitable for the production of small-sized aluminum discs.

Why is the quality of our aluminum discs second to none in China?

In order to ensure the quality of aluminum circle disc, Chalco Aluminum sets up specialquality inspectionposts during the production process.

1. The surface of aluminum circle disc

The aluminum circle disc with good quality has no deformation, scratches, cracks, yellowspots, etc. And thesurface color of high-quality aluminum circle is consistent. If there is color difference, thequality isunqualified.

2. Chemical composition

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

3. Mechanical properties

The tensile strength and mechanical properties of aluminum rounds are tested by a tensile testingmachine to ensurethat the tensile strength and elongation meet the standards. If the mechanical properties are not upto thestandard, it is easy to break during the stamping and spinning process. It will waste a lot of timeand materialcosts in production.

The tensile strength of aluminum circle disc 1050-O is generally 60Mpa to 100Mpa; Elongationis about 35%. Thetensile strength of aluminum circle disc 1050 H12 is generally about 100Mpa, and theelongation is about 10%.

4. Particle size test

Different manufacturers have different requirements for grain size. According to internationalstandards, mostfactories control the particle size above Grade II, while some large factories require the particlesize to be GradeI. This can ensure that the yield of aluminum circle disc reaches 98% or even 100% during theproduction ofkitchenware.

Price quotation for aluminum circle disc

Generally, the processing price of aluminum rounds varies according to different alloys andwidths.We can processaluminum rounds according to the order quantity, and the price will also decline. We look forward toyour consultation.

Price calculation method:

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

Packaging and transportation of aluminum circle disc

1. Aluminum circle disc are usually packed in a crossing girder way, and the packaging shouldmeet the needsofstorage and transportation.

2. During the transportation process, a layer of neutral or weak acid material shall be wrapped onthe surface ofaluminum foil roll and then put into the packing list.

3. The lap joint shall be fixed with adhesive tape and padded with soft cushion to protect the endface of aluminumfoil roll.

4. Put desiccant in the roll and wrap it with plastic cloth. The sealing part of the outermostplastic cloth shallbe firmly stuck with adhesive tape, and the remaining parts at both ends of the plastic cloth shallbe insertedinto the pipe core.

5. Finally, put the wrapped aluminum foil roll on the cross and fix it with steel tape, and thenstick a case cardon the end face of the aluminum foil roll.

6. Pay attention to the method of transportation, and handle with care when loading and unloading.

Frequently asked questions about aluminum circles discs

How do I choose the right alloy for my application?

It depends on your process and end-use. For deep drawing cookware, 1050 or 1060 is ideal. Forcorrosion resistance andstrength, 3003 or 5052 is better. We can help you select the right grade based on your needs.
