The difference of 6000 series aluminum sheet in different states

The difference of 6000 series aluminum sheet in different states

It is well known that different aluminum sheet is divided into different series, and even different properties and uses of the same series are also different. Here to explain the difference between the 6000 series aluminum sheet in different conditions.

6061 aluminum sheets and 6082 aluminum sheets are the representative of the products of the 6000 series, and the states of T6, T5 are common states.
Before the understanding of T5 and T6 state, it is needed for everyone to spread the knowledge: aging and quenching.
1, aging: the process of eliminating internal stress of metal.
2, quenching: the metal is heated to a certain temperature and then cooled to the desired hardness. 2000, 6000 and 7000 series aluminum sheet can improve the strength by quenching treatment.
T5 refers to that the aluminum sheet is extruded from the extruder and then the temperature is reduced rapidly to achieve the required hardness (Webster hardness 8–12). T6 refers to that the aluminum sheet is extruded from the extruder with water to make instantaneous cooling to achieve higher hardness (Webster Hardness of the above 13.5).
The cooling time of air cooling is relatively long, and usually there will be 2-3 days, we call it a natural aging. However, we call short cooling time is artificial aging. The main difference between T5 and T6 States is that the intensity of the T6 state is higher than that of the T5 state, and other properties are similar. In terms of price, because of the difference in the production process, the price of T6 statealuminum sheet is higher than the T5 state 500-1000 yuan per ton.

How much is a ton of aluminum sheet?

How much is a ton of aluminum sheet?

Aluminum sheet refers to the thickness of aluminum material is greater than 0.2mm , less than 200mm, and Its length within 16m. And it is also called aluminum plate or aluminum sheet. Technically, aluminum sheet refers to the rectangular sheet with aluminum ingot rolling processing, divided into pure aluminum sheet, aluminum alloy sheet, thin aluminum sheet, medium thick aluminum sheet and figured aluminum sheet.

The different sizes and thicknesses of aluminum sheet have thousands of specifications. So how to calculate the aluminum sheet price and what is the determining factor?
1. The price of aluminum ingots:
As we all know, the prices of aluminum ingot fluctuate from day to day. Therefore, with the prices of aluminum ingot fluctuating, manufacturers of the same specifications of the aluminum products will also offer different prices. For example, the price of aluminum ingot was 10960 one day, but today the price is 9900, then if you buy aluminum now, per ton of aluminum sheet price will have 1060 yuan cheaper at least.
2. Processing costs:
The processing cost per ton of different alloy grades product is different. Even the same type of aluminum sheet, the inquiry of different enterprises may also have different costs. This is related to the equipment capacity, product quality and other costs.
In Henan, for example, the production of a certain specification of 1060-H18 aluminum alloy coil processing costs is about 1800 yuan in Mingtai Al, while the processing cost of 6061-T4 aluminum sheet is more than $10000 per ton. While the offer of other companies is not the same, the main reason is the strength of the manufacturers, cost control, quality control and other aspects of the impact.
3. Freight:
For large aluminum industry products, logistics and transportation is an important part of aluminum sheet sales. The transport distance and the number of goods have affected the calculation of aluminum sheet freight. In general, the average cost per ton of aluminum sheet is 300-500. Under normal circumstances, some larger manufacturers equipped with a more complete logistics system, and you can save some of the overall transport costs. Therefore, the aluminum sheet price = (aluminum ingot price + processing fees + freight) * number. A ton of aluminum sheet prices, by the current price of aluminum ingot + processing fees, as long as querying the price of aluminum ingot and consulting the manufacturer for aluminum processing fees, then “how much money a ton of aluminum sheet” can be a very simple calculation.

What is the difference between an impurity and an inclusion in the aluminium industry

What is the difference between an impurity and an inclusion in the aluminium industry

From my industry experience at a sheet rolling company, we did use the term inclusion for everything that was not supposed to be part of the final microstructure. Not mentioning cracks here.
You could have constituents / intermetallics (like α-Al(Mn,Fe)Si) which always form during the direct chill casting operations, because of limited solubility of elements in the melt.. The goal is to reduce their number and size again during the rolling operations, so they will not create weak spots in the metal. They are brittle and break up into sharp pieces, which can act as local stress riser. Usually you aim for sizes smaller than 10µm, otherwise you get in trouble in later forming operations.
Other sources of undesirable features in your microstructure can be the result of your melting operations. This can include oxides that form in melting and holding furnaces, and are not completely skimmed off or filtered out. Another problem could come from agglomerated grain refining elements that are added to the melt. This would lead to trails of titanium boride in your metal. Bad melt handling and alloying practice, can lead to inhomogeneous chemistries along the ingot.
Impurities would refer to substances or elements present in the metal, that would not necessarily occur during operations or are part of the desired chemical composition. This could be pieces of refractories (ceramics) from the furnace insulations or launder systems. Or others substances that made it through the filters (or could be even broken bits from the filters).

What is the high performance of mirror aluminum sheet 3003?

What is the high performance of mirror aluminum sheet 3003?

Aluminum-manganese alloy mirror aluminum sheet 3003 has good performance in rust resistance and corrosion resistance. Anyone who knows mirror aluminum sheets knows that there are many specific varieties in terms of materials and crafts. From the material point of view, there are three main types, the pure aluminum mirror sheet, the Al-Mn aluminum mirror sheet and Al-Mg mirror aluminum sheet, among them, the aluminum-manganese alloy mirror aluminum sheets have good performance in rust resistance and corrosion resistance, and the quality and performance are at a medium level.

The aluminum-manganese alloy mirror aluminum sheet is a kind of rust-proof aluminum from the material point of view. It has certain anti-rust performance under the material’s promotion, and can be used in the case of less strict anti-rust, and it is not easy to appear rust. Compared with the ordinary aluminum alloy mirror aluminum sheet, the aluminum-manganese alloy aluminum mirror sheet 30030has slightly higher strength, which means that the 3003 aluminum mirror sheet can withstand the external force when it is used, and it is not easy to damage the structure due to the impact of external force, and relatively more capable to maintain a stable structural state during use to ensure reliable functioning.
The mirror aluminum sheet 3003 has a certain corrosion resistance, although it does not reach the degree of hardness and corrosion resistance of the aluminum-magnesium alloy aluminum mirror sheet, but it is better than the mirror aluminum sheet alloy of the ordinary alloy composition.

What is a pure aluminum sheet?

What is a pure aluminum sheet?

Aluminum sheet, as its name implies, is made of aluminum or aluminum alloy material. Or it is the type of aluminum products by flat aluminum embryo through heating, rolling and straightening or solution and aging process made.

The lowest aluminum content of the pure aluminum sheet shall be determined by the final number of the series code of the aluminum sheet, for example, the last two number of the 1050 series are 50. According to the world standard, the aluminum content must reach the 99.5%, and then it can be called the qualified product. The technology standard of the aluminum alloy in (gB/T3880-2006)also clearly stipulate the aluminum content must be over 99.5%, and it is the same to the other series of the aluminum sheet.
There are many advantages in the pure aluminum, first, it can be strengthened, the strength can be increased through the cold processing, and the element of Mg, Zn, Cu, MN and SI-L can all be added to it and make the alloy, and the strength will be increased through the hot conduction. The strength of it can be comparable with the high quality alloy. The density of the pure aluminum sheet is small, the density of it is near 2700 kg /m3, and it is the 35%of the density of the iron. Besides, it is anti-corrosion, the surface of the aluminum and its alloy is easy to form a film on the surface, and it is the A 1203 protection film, and this protection film will be destroyed only with the strong action of the alkali ion, so it can bear the influence of the air.
