The pattern aluminum sheet is a high cost modern material. There are many kinds of materials. It is widely used in furniture, such as refrigerator, air conditioner, carriage, platform, packing pipe, screen frame, all kinds of hanging beams, table feet, decorative strips, drawing hand, walking groove and cover, chair pipe and so on.
![[Image: aluminumdiamondplate.jpg]](http://thick-aluminum-plate.com/images/aluminumdiamondplate.jpg)
Using a pair of steel rolls, the pattern is carved on the steel roll, the section of the section two steel rolls center distance and the steel roll rotation, the flat aluminum plate is passed between two steel rolls, and the pattern is imprinted on the aluminum plate. This is just one technology, and there are many other differences. We need to specify the processing technology accordng to the pattern. Like the big five ribs, the reverse side should be flat since it is pressed.

Advantages of copper clad aluminum wire:
1. Dc resistivity: the dc resistivity of the copper clad aluminum wire is about 1.5 times that of the pure copper wire, and the copper clad aluminum wire is about 1/2 the weight of the pure copper wire. According to the "skin effect" calculation, the resistivity is the same as the pure copper wire at the high frequency of 5MHZ.
2. Good weldability: copper clad aluminum wire has the same solderability as pure copper wire due to its concentric coating of pure copper.
3. Light weight: the proportion of copper clad aluminum wire is only 37% - 37% of pure copper wire, online diameter, under the condition of equal weight, the length is 2.5 times of pure copper wire, thus greatly reduces the production cost, buy 1 ton of copper clad aluminum wire is bought 2.5 tons of pure copper wire;
4. Copper clad aluminum wire has obvious advantages over pure copper wire: light weight, convenient transportation, soft and easy to process, saving copper resource consumption and low cost. The cost comparison between the copper clad aluminum wire and the pure copper wire:
The density of copper clad aluminum is 3.63g/cm3, the copper density is 8.89g/cm3, and the density ratio is 1:2.5, so the length of 1000kg copper clad aluminum magnesium alloy wire is equivalent to the length of the pure copper wire of 2500kg.
For example, the copper clad aluminum wire has a price of 72 yuan /kg. Pure copper bare wire is sold for 48.6 yuan /kg.
The cost of saving is about 48600 yuan (48600 yuan * 2.5 times - 72,000 yuan =48600 yuan) using 1000kg of copper clad aluminum wire and 2500kg pure copper wire.
Therefore, the use of copper clad aluminum wire instead of pure copper wire can greatly reduce the cost of raw materials.

Aluminum alloy is the most widely used nonferrous metal structure material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of science and technology and industrial economy in recent years, the demand for aluminum alloy welding structure is increasing, and the welding research of aluminum alloy is also deepened. Aluminum alloy is widely used to promote the development of aluminum alloy welding technology, at the same time, the development of welding technology and expand the application field of aluminum alloy, thus the welding technology of aluminum alloy is becoming one of the hot spot of research. Aluminum alloy: aluminium based alloy general term. The main alloy elements are copper, silicon, magnesium, zinc and manganese, and the secondary alloy elements are nickel, iron, titanium, chromium, lithium, etc.
The density of pure aluminum (rho = 2.7 g/cm3), is about 1/3 of the iron, low melting point (660 ℃), aluminum is face-centered cubic structure, therefore, has the very high plasticity (delta: 32 ~ 40%, and bits of: 70 ~ 90%), easy to machining, can be made into various molding, plate. Good corrosion resistance; However, the strength of pure aluminum is very low, and the value of the annealing state is about 8kgf/mm2, so it is not suitable for structural materials. Through long-term production practices and scientific experiments, people gradually strengthened aluminum by adding alloy elements and using heat treatment methods, which resulted in a series of aluminum alloys. In addition, the alloy with certain elements can have high strength while maintaining the advantages of pure aluminum, and the value of b can be up to 24 ~ 60kgf/mm2 respectively. So that its "strength" (the ratio of intensity and the proportion of sigma b/rho) is better than a lot of alloy steel, become the ideal structural material, widely used in machinery manufacturing, transportation, machinery and aviation industry, the aircraft fuselage, skin, such as compressor with aluminum alloy manufacture, in order to reduce weight. Using aluminum alloy instead of steel plate material welding, the structure weight can be reduced by more than 50%.
Aluminum alloy density is low, but the intensity is high, close to or more than high-quality steel, plastic, can be processed into various profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used on industry, usage is second only to the steel.
The billboard of general outdoor USES aluminium alloy board is good.

Aluminum is a metal substance, which is not a trace element needed by the human body, and the amount of aluminum in food that exceeds the national standard can be harmful to human health.
If excessive consumption of aluminum or aluminum excessive amounts of food consumption, affect the normal metabolism of human body cell, affect a series of biochemical reactions, can cause memory loss, cause the problem of dementia in the elderly. As for children, in the process of growth and intellectual development, excessive consumption of aluminum can seriously affect the intellectual development of children.
In foods with excessive aluminum consumption, aluminum can accumulate in the body continuously, causing pathological changes in the nervous system, interfering with people's thinking, consciousness and memory function, and may lead to dementia. Excessive intake of aluminum may also cause calcium loss in bone, inhibit bone formation, and osteomalacia.
Once the aluminum salts enter the human body, they are first deposited in the brain, which can cause brain damage and cause severe memory loss, which is a characteristic of alzheimer's disease. The researchers, who were involved in the work, said experiments with mice showed that the amount of aluminum in their brains reached measurable levels after just drinking a glass of water treated with aluminum salts. A study of rats found that trace amounts of aluminum mixed in drinking water entered the brain and gradually accumulated there. Researchers study of dementia patients, found that these patients, 30% new brain cortex in aluminum concentrations greater than 4 micrograms per gram (dry weight), patients with brain neurons within the nucleus, the aluminum content is four times that of healthy people, the largest up to 30 times. The researchers believe that, over time, aluminum accumulates in the brain, killing neurons and causing memory loss. 'we've spent our lives drinking aluminum salts and eating foods that contain aluminum,' says one scientist. 'so when we're old, we've built up a lot of aluminum.' He points out that the incidence of alzheimer's disease has risen worldwide in the past 70 years. Aluminum is also used in food emulsifiers, he said.
Aluminum can directly damage the activity of osteoblasts, thereby inhibiting the matrix synthesis of bone. At the same time, the absorption of aluminum by the digestive system leads to the increase of urinary calcium excretion and the deficiency of calcium in the human body. Aluminum accumulates and performs physiological functions in the human body, which can also cause encephalopathy, bone disease, kidney disease and non-iron deficiency anemia.
To prevent the harm of aluminium article there are three main ways: one is the recommended city tap water company in line with the aim of responsible to the people to oneself, do not use aluminum salt [such as potassium aluminium sulfate (KAI (SO4) 2) water purifier; 2 it is as far as possible need not aluminum cooker; 3 it is to eat less food containing aluminium salt additives is more (e.g., Fried dough sticks).
Aluminum is very toxic to human body, and it is toxic to biology. Soluble aluminum compounds are toxic to most plants, and the dissolved aluminum compounds in the water of acidic soil make it difficult for normal crops to grow properly. Usually when the dissolved aluminum reaches 10 to 20PPM, the plant will have an aluminum toxicity. The aluminum in the soil can be combined with soluble phosphate to produce insoluble phosphoric acid, which causes the plant to die without phosphorus. Aluminum also dehydrates plant cells and destroys them. The combination of aluminum and pectin in the cell wall strengthens the crosslinking structure of pectin, which hinders the absorption of water and nutrients. The mineral nutrients such as calcium and phosphorus in plants are closely related. It can inhibit the absorption and accumulation of calcium and phosphorus in general plants, and also affect their absorption and accumulation of elements such as potassium, magnesium, manganese, copper and zinc. Aluminum to aquatic animals also have poison, when pH is about 5, deposition in aluminum hydroxide form within the gills, made it difficult to make oxygen into the blood, fish salt concentration in the body and the imbalance, causes the death of fish. The toxicity of aluminum to aquatic animals is generally 70 micrograms per liter. The increase of aluminum content in the water will result in a large amount of organic matter coagulation, which will cause aquatic animals to die due to lack of nutrition. Aluminium can precipitate phosphorus and seriously threaten the reproduction of aquatic animals.
