How to Choose Aluminium Discs Cut to Size

The aluminum discbound discs is widely used in kitchenware such as aluminum pots, frying pans, baking pans and lighting like lampshades, bases and decorative lights because of light weight, smooth surface and excellent electrical and thermal conductivity.

When we buy aluminium discs cut to size, we can choose different levels according to different applications. The aluminum discs with the deep drawing rate over 1.8 is suitable for the production of kitchen utensils in the later deep-drawing process; some are suitable for making deep drawn lamps; some are suitable for the production of kitchen utensils in the later spinning process.

We also need to stress the quality of aluminum sheet circle. There should be no obvious scratches, oil stains, oxidation, dark spots, no burrs, etc. The excellent control of the grain size and elongation of the coil in the early stage ensures the deep drawing and spinning functions of the aluminum discs.

Compared with aluminum plate and aluminum coils, the aluminum discbound discs price is a little higher. For the aluminum discs, the additional continuous stamping process will increase production costs.

What’s more, one ton of aluminum circles will produce 10-15% of waste, and some special specifications of aluminum discs will produce more waste, which directly leads to the high price of aluminum sheet circle. So if the aluminum circle price is lower than the normal level, the quality may be very poor.

With 160 tons punch, automatic production line and special mold, the production efficiency of Haomei aluminum discs cut to size has been improved greatly, therefore we can offer you a better price. Welcome to leave message to inquire what you need.

It is not only used in factories and warehouses, but also commonly used in the daily goods such as refrigerators, air conditioners, table legs, decorative strips, and handles. 3mm aluminum tread plate is a common specification. How to choose it?

1. We should pay attention to luster. The aluminum tread plate luster is closely related to its production process and quality control. If the color of the product is bright and the gloss is high, it is generally better than the product with poor color.

2. It is necessary to choose a 3mm aluminum tread plate with uniform thickness. The thickness is also an important factor to test the quality of the aluminum checker plate. The thickness of aluminum tread plate on the market is usually under tolerance.

For example, the thickness of 3mm aluminum checker plate is usually only 2.5mm in actual measurement thickness. Try to choose a aluminum tread plate with a smaller thickness tolerance.

3. At the same time, you need to pay attention to the height of the pattern when purchasing aluminum tread plates. Try to choose products with full patterns and higher protrusions, because only full patterns can have a good anti-skid effect.

4. We should also stress its surface quality. The quality aluminum checker plate surface is bright and clean, its pattern is clear and tidy and the surface is free of defects such as oil, scratches, and breaks.

5. 3mm aluminum checker plate price is also a factor that counts much. The aluminum tread plate can be divided into pure aluminum and aluminum alloy. The aluminum alloy plate price is naturally higher than that of pure aluminum tread plate. The aluminum tread plate price from the reliable manufacturer is about 20%-30% higher than that of inferior aluminum plates.

How to Prevent Pinholes in Aluminum Foils

The application fields and demand of aluminum foil packaging material both has rapid development, especially the light gauge foil. In addition to electrolytic capacitors, more than 90% of the aluminum foil for packaging is light gauge foil.

The irregular small holes visible on the surface of the aluminum foil are called pinholes. As the thickness decreases, the number of pinholes increases, which is one of the main defects of aluminum foils. When the thickness is above 0.02mm, the aluminum foil can be completely pinhole-free.

It is the existence of pinholes that makes the oxygen transmission rate and water vapor transmission rate of aluminum foil not zero. The size and number of aluminum foil pinholes have a decisive influence on the moisture resistance, gas barrier properties and light-shielding properties of aluminum foil and its composite materials.

Dust in the blank, on the roll, in the rolling oil, or even in the air that reaches a size of about 6μm into the roll gap will cause pinholes. How to prevent pinholes in aluminum foils?

With the improvement of the installed level of aluminum foil equipment, the aluminum foil rolling conditions have been improved, especially the effective filtration of dust and rolling oil and the quick setting of roll changing system. It is now more related to the metallurgical quality and processing defects of the blank.

It is generally believed that pinholes are mainly related to gas content, inclusions, and compounds and component segregation of the blanks. Adopting effective aluminum liquid purification, filtration, grain refinement, etc. all help reduce pinholes. The use of alloying and other means to improve the hardening property of the material also helps to reduce pinholes.

The rollers replacement and dust-proof measures are all necessary conditions to reduce pinholes in aluminum foil. Rolling with small tension will also help reduce pinholes. We also need to strengthen the filtration of rolling oil.

The pinholes of 6μm aluminum foil rolled by high-quality aluminum blanks can be less than 100/m². With advanced rolling technology, the common specifications of Haomei foil packaging material is free of pinholes.

What Is Bendable Aluminum Strip

The flat aluminum strips is of wide application, including pharmaceutical caps, cosmetics caps, transformer winding material,cable armouring, LED strips, fin stock, can making material. Among these applications, some require the aluminum strip is bendable.

The bendable performance of aluminum strip has close relationship with its alloy, temper and thickness. As we all know, the aluminum alloy has eight series. The 1xxx aluminum strip is a kind of flexible aluminum strip, having good thermal conductivity, electrical conductivity, and good ductility. It has good bending and stamping performance in the H24 semi-hard temper.

3xxx and 5xxx aluminum has a certain strength and good bending performance such as 3003, 5052 and 5154 aluminum strip. 6061T6 aluminum strip is a high-hard aluminum strip, one of the hardest products among all aluminum strips, which is not suitable for bending.

According to the different annealing tempers, the aluminum strips can be divided into full soft (O temper), semi-hard (H24 temper), full-hard (H18 temper). The O temper aluminum strip is easier to stretch and bend. The semi-hard aluminum strips generally can be bent. We will not choose the full hard aluminum strip to bend, which is easy to crack.

The aluminum strip’s bending performance is also been affected by its thickness. The bending coefficient is generally the 0.8 times the thickness of the bendable aluminum strips. Take the aluminium strip 3mm for example. Its bending coefficient is 2.4. Generally the aluminum strip has rolling lines. It is best that the bending tool and the rolling line intersect 90 degrees.
