What is an aluminum coil?

Aluminum coil is a metal product that is cast and rolled for flying shear after calendering, bending, and straightening process. Aluminum coil is widely used in electronics, packaging, construction, machinery, and other aspects. 


After the Shanghai aluminum coil market survey, the amount of aluminum coil is about 3 million tons. The specific use: the amount of aluminum veneer for vehicles and ships is about 300,000 tons, the amount of color coated aluminum coil is about 100,000 tons, electronics for about 200,000 tons, containers and packaging about 100,000 tons, stamping parts and other uses about 400,000 tons, aluminum coil flattening about 200,000 tons. Shanghai port exports about 700,000 tons (sold to countries in order: the Middle East, the Americas, Europe, Russia, Africa, etc.). Due to the lightweight aluminum coil, the relative price is low, such as coupled with the alloy hardness, with high plasticity, relative to other metal dosages in accelerated growth.


According the aluminum coil contains different metal elements, can be divided into 8 series. The commonly used grades are:

Aluminum Coil: 1050, 1060, 1100, 1200, 3003,3004, 5052, 5754, 5083, 6061, 8011

What is the difference between a 1050 O aluminum coil and a 1050 H14 aluminum coil?

First of all, we should know that temper O is a state of aluminum coil. It is the product of the aluminum coil after annealing. The same grade of aluminum alloy is divided into O state and H state two different forms.


In terms of the production process: The O state aluminum sheet is formed after complete annealing and crystallization, while H14 is the state of incomplete annealing after processing hardening.


In terms of physical properties: The O state aluminum sheet is softer, while the H14 state aluminum sheet is harder compared to the O state. In other words, the hardness of the 1050 aluminum coil in the H14 state is greater than that of the 1050 aluminum coil in the O state.


From the use of the scope: because the O state aluminum plate is relatively soft, so it is easy to bending and deep drawing, mainly used in decoration, packaging, and other industries. And H24 state is harder, can be drawn, shear, bending, generally used in curtain wall, mechanical processing, and other industries more.


How many meters per coil? What’s the length of a coil?

Many people who are doing engineering projects do not know the calculation of aluminum coil meters. They are often very curious about the number of meters of aluminum coils. But for the aluminum coil meters calculation method, is actually a very simple calculation method. Today we teach you this method as long as you can learn, will be able to learn to calculate the calculation of aluminum roll meters very well.


First of all, the weight of the aluminum sheet is calculated by the formula: Aluminum sheet weight = thickness of aluminum sheet X width of aluminum sheet X length of aluminum sheet X density of aluminum sheet. So, after going through this calculation, we come to work backward so that we can know the exact number of meters of aluminum rolls.


Aluminum coil meter calculation formula: Weight ÷ (thickness X width X density) = aluminum coil meters. For example: 3003 H14 aluminum coil, Weight: 2700KGS; thickness: 0.7mm, width: 1220mm. Aluminum Coil length = 2700KGS÷(0.7mm x 1.22m x 2.73) =1158 Meters.  


What’s the price of an aluminum coil? How much does aluminum trim cost?

Nowadays, the market of aluminum plate and coil development is expanding, and the price of aluminum coil is our concern. How much does aluminum coil cost? How to buy an aluminum coil? The general price is composed of aluminum ingot price and processing charges. Aluminum ingot prices are based on the market every day released ingot prices. Processing fees are based on the manufacturer’s input costs have a reasonable price.


Different manufacturer’s input costs will be different, there will be high and low prices. But the price will not be too much different, this mainly depends on the cost of manufacturers. For example, today is October 15, 2019, the price of aluminum ingot today is 14000RMB/TON, about 2060USD/TON. The price of aluminum coil 3003 H14 size: 0.5mm x 1000mm x L is now FOB Qingdao: 2290USD/TON.


What is thermal insulation aluminum coil?

Insulation aluminum coil has various colors, beautiful appearance, and strong decorative power, which is widely used in exterior wall insulation, pipe insulation, and building decoration. Insulation aluminum coil as a new type of insulation material has the characteristics of rainproof, anti-collision, long service life.


Insulation aluminum coil is mainly divided into two series: pure aluminum coil (1050 aluminum coil) and 3003 aluminum alloy coil. Now the insulation project is more favorable to make in 3003 aluminum volume. Because pure aluminum coil in the price gap is not very big. 3003 insulation aluminum coil has better corrosion resistance, for some corrosive gas and liquid pipeline need this aluminum coil. 1050 insulation aluminum coil is suitable for the requirements are not high and does not contain corrosive liquid engineering use, and the use of relatively low cost.


The common thickness of the insulation aluminum coil is mostly below 1mm. The common thickness are 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.2mm. width is 1m width. Insulation aluminum coil according to the project budget according to the number of squares to purchase, most of the insulation project insulation aluminum coil dosage is relatively large, and the delivery time requirements are relatively strict.


What is a color-coated aluminum coil? How to produce aluminum coil to aluminum roofing sheet or aluminum tile?

The color-coated aluminum coil production process is introduced: coated aluminum coil refers to the aluminum coil surface color coating effect of a product, can also be called a color-coated aluminum coil, color aluminum coil. The purpose of the coating process is to have a beautiful effect in the field of construction, decoration, home, etc. Secondly, because the coating process and coating thickness will affect the quality and service life of coated aluminum coil products directly.


The general production process of strip coil coating has 5 steps, namely strip coil input, cleaning and chemical treatment, painting, curing, and finished product output. The process layout and equipment composition vary from case to case, but the basic parts are the same.


Both Pre-coated aluminum coil and bare aluminum coil are also wildly used for aluminum roofing sheets.


How to store and transport aluminum coils?

1. Wrap the aluminum coil with plastic film. If the conditions allow, it is best to be placed in a place with desiccant, so that the moisture inside the air can be absorbed, thus avoiding the problem of oxidation. 


2. If the aluminum coil is placed inside the wooden box, then we have to ensure that the humidity of the wooden box should be less than 18%, and the temperature of the aluminum coil can not be higher than 45 ℃;


3. If during the placement suddenly from the low-temperature region to the high-temperature region, we should not open the package immediately. Because it is easy to appear oxidation, we should wait until the aluminum coil to adapt before unpacking, so that there will be no oxidation;


4. If the warehouse inside the leakage of rain, leakage of snow, they should not place the aluminum coil, so it is easy to make it appear oxidation. This point must be remembered. Keep it in a dry warehouse
