What is aluminum circle?

Aluminium Circle also named Aluminium Disc, widely used in electronics, daily chemicals, medicine, culture and education, and auto parts. Electrical appliances, heat preservation, machinery manufacturing, automobiles, aerospace, military, molds, construction, printing and other industries. Such as kitchen utensils such as non-stick pans, pressure cookers, etc., and hardware products such as lampshades, water heater shells, etc., are some of the most used Aluminium alloy plate and strip deep-processing products.

Henan Huawei Aluminum Co., Ltd is mainly engaged in the export trade of Aluminium Circle, Aluminium plates, coils, strips, belts, foils and other non-ferrous metal products. We have established long term business shipment with more than 80 countries.

Benefits of Aluminium Circle

• The surface performance of the Circle is good, ensuring no obvious scratches, oil stains, oxidation, black spots, etc;
• Circle specifications are available. In addition to the regular size, Circle with the thinnest 0.5mm and the thickest 6.5mm can be provided;
• When the thickness of the Circle is greater than 1.0 mm, ensure that the edges of the finished product are neat and free of burrs;
• The good control of the coil grain size and elongation in the early stage ensures the excellent deep drawing and spinning performance of the wafer, effectively avoiding the possibility of later processing，Undesirable phenomena such as the drawing pattern, lotus leaf edge, and high ear-making rate;
• Strictly control and test the alloy, state and performance of the coils to ensure the accuracy and diversity of the wafers provided;
• The introduction of advanced and efficient production equipment has improved the production efficiency of wafers and the utilization rate of materials, effectively shortened the production cycle and provided customers with real-time convenient services;
• The Circle are classified in detail, and the exact type can be selected according to the different purposes and requirements of customers;
• The product complies with ROHS and REACH environmental protection standards;
• The product packaging is firm, in line with domestic sales and international export standards.

Aluminum Disc Production

In the process of aluminum disc production, there are several links of particular importance.

1. Billet: the main check grain size and aluminum content, must reach the grain size of grade 1 and more than 99.5% aluminum content, before the production of aluminum discs, the main factor affecting the grain size is the titanium content of the melting process, we require titanium content of not less than 0.15%, only then can guarantee the quality of the billet, the above 2 indicators The above 2 indicators directly affect whether the aluminum discs will be pulled when spinning to produce aluminum pans, whether the surface of aluminum pans will have orange peel pattern, tiger skin pattern and other undesirable phenomena.
2. Rolling: it is from the billet 6.0mm calendering to the required thickness of aluminum discs. In the process of calendering and rolling, we should strictly control the amount of rolling pressure in each pass, the amount of pressure in each pass is not more than 60%, that is to say, from 1.0mm, the maximum calendering to 0.6mm, the one-time pressure is too large, it will also affect the quality of aluminum products later. The same plate thickness tolerance plus or minus 0.01mm, but also to control the thickness and width.
3. Punching aluminum rolls into aluminum discs, after the stamping workshop receives the rolled aluminum rolls with the required thickness, it starts stamping by checking the thickness, width, and other external dimensions, and this process mainly controls whether the diameter of aluminum discs is correct (diameter tolerance plus or minus), whether the aluminum discs are scratched, whether the aluminum discs are deformed, the side burrs, the number of pieces, etc. As the gap between the upper and lower die will gradually become larger during the use of the stamping die, the edge burr of the aluminum disc will become thicker and longer, which will easily stab the workers’ hands during the later handling and spinning process. So the stamping dies should be checked regularly for tolerance and trimming. Our company adopts precise control of quantity, which means that each set of dies should be trimmed after how many times of stamping.
4. Annealing: turn the aluminum disc in H state into 0 state. Annealing furnace heating time of 6 hours, heating up to about 200 degrees to begin to remove oil and smoke (because this temperature aluminum disc above the rolling oil has begun to atomize), from room temperature heating to 380 degrees, constant temperature of 380 degrees to maintain 20 hours, the length of insulation time will have a great impact on the elongation of aluminum discs, and then cool down the natural cooling.
5. Packaging: in order to prevent the long transport process between the aluminum discs of static electricity, the need to sandwich paper between the aluminum discs, not every piece is added, we control the standard is about 10cm thickness sandwich a paper, and then is waterproof, moisture-proof, such as 4 layers of packaging, the following is fumigated wooden pallets, the top is a multi-layer board of wooden cover, 2 vertical and 2 horizontal steel belt packing.
