Precautions for aluminum sheet drawing process

Precautions for aluminum sheet drawing process

Stretching is one of the processing methods of aluminum brazing sheet plate. Stretching aluminum sheet is produced by stretching the aluminum and aluminum fittings made after, but the tensile aluminum sheet generally can not be too hard, too hard will pull the explosion, so the Elongation and tensile strength of aluminum alloy sheet, etc. Depending on the stretch-height and stretch method will have different requirements, 5052 aluminum sheet often need to be stretched during use.

In addition to pay attention to the tensile height of 5052 aluminum plate, its own hardness, but also need pay attention to their own performance, the product to achieve the best results, their performance can not be damaged in the process of stretching, to give full play to the product Performance advantages.
Precautions for aluminum sheet drawing process:
Tensile aluminum alloy sheet is produced in the implementation of aluminum stretching technology, the use of processing, there is an increase in the production process of stretching this process is to eliminate the internal stress of aluminum and enhance the flatness, which is called pre-pull Stretch, suitable for high hardness aluminum alloys, 5052 aluminum alloy sheet in the production process in order to increase the flatness will use the pre-stretching technology, but to the hardness range. Casting and hot rolled aluminum plate can be used for stretching, but the effect of cast rolled aluminum plate is not ideal, so commonly referred to as the hot rolled aluminum alloy sheetare generally.

The major incentive for employing aluminum is its weight saving compared to steel. Because it is common practice to use weldable aluminum alloys having strengths approaching or comparable to mild steel, equal-strength structures can be designed to a weight saving of 55 to 67%. However, to compensate for the lower modulus of elasticity of aluminum and to conform to normal deflection limitations, a somewhat lower, but substantial, reduction in weight is usually obtained. Aluminum is used in hulls, deckhouses, and hatch covers of commercial ships, as well as in equipment items, such as ladders, railings, gratings, windows, and doors. The major incentive for employing aluminum is its weight saving compared to steel. Because it is common practice to use weldable aluminum alloys having strengths approaching or comparable to mild steel, equal-strength structures can be designed to a weight saving of 55 to 67%. However, to compensate for the lower modulus of elasticity of aluminum and to conform to normal deflection limitations, a somewhat lower, but substantial, reduction in weight is usually obtained. The principal advantages of weight saving in many types of marine vessels are to increase payload, to expand capacity for equipment, and to decrease the power required. With other types of vessels, the chief benefit is to permit better distribution of the weight, improving stability and facilitating efficient hull design. The use of aluminum normally results in initial cost premiums that are justified over the life of the application by the benefits of lightweight and low maintenance cost. The weight saving achieved depends on the approach to design, which varies with different applications. Where known or rule loadings exist for specific structures, normal design principles are applied along with consideration of the mechanical properties of specific alloys. Alloys. The 5xxx series alloys used for the majority of commercial marine applications have weld yield strengths of 100 to 200 MPa. These aluminum-magnesium alloys retain good weld ductility without postweld heat treatment, and they can be fabricated with normal shipyard techniques and equipment. The weldable aluminum-magnesium-zinc alloys are also receiving attention in this field. The corrosion resistance of the 5xxx series alloys is another major factor in the selection of aluminum for marine applications. Tensile strength reductions in 10-year sea-water corrosion tests of 1.62mm (0.064-in.)-thick bare sheet specimens are only 2 to 5%. The 6xxx series alloys, widely used for pleasure boats, show a 5 to 7% decrease in similar tests. Alclad aluminum alloys are seldom required in construction of marine vessels. They are used, however, in a few applications, such as piping, for maximum assurance against excessive depth of pitting. Also, alclad 2xxx and 7xxx series alloys are selected where tensile strengths of 70,000 to 80,000 psi (482.6-551.2 MPa) are required, considerably higher than now available in the 5xxx series alloys. The high-strength alloys are employed where welding is not required, and where their higher strengths can be used to advantage. Because of their lower resistance to corrosion by sea water, protective measures such as cladding, painting, or cathodic protection must be used for satisfactory life in marine service

copper

The maximum solubility of copper in aluminum is 5.65%, and the solubility of copper is 0.45% when the temperature drops to 302. Copper is an important alloy element, which has certain solid solution strengthening effect, and CuAl2 has obvious aging effect. The copper content in aluminum alloy is usually 2.5% ~ 5%, and the copper content is the best when 4%~6.8%, so the copper content of most hard aluminum alloy is in this range. Aluminum copper alloy can contain less silicon, magnesium, manganese, chromium, zinc, iron and other elements.

silicon

The maximum solubility of silicon in solid solution was 1.65% when the eutectic temperature of Al - Si alloy was 577. Although solubility decreases with temperature, such alloys are generally not heat-treatable. Aluminum silicon alloy has excellent casting performance and corrosion resistance. If magnesium and silicon are added to aluminum to form the aluminum magnesium silicon alloy, the enhanced phase is MgSi. The mass ratio of magnesium and silicon is 1.73:1. When designing the composition of al-mg-si alloy, the content of magnesium and silicon is configured on the base. Some of the al-mg-si alloys, in order to increase the strength, add a moderate amount of copper, and add a moderate amount of chromium to offset the adverse effects of copper against corrosion.

Food packaging foil almost no impurities, Applicable to food, cosmetic, machinery, electronics, lubricants and other industries, aluminum foil production of food packaging is a better use.


The use of aluminum foil made of food bags have the following advantages:

High temperature (up to 121 degrees), low temperature (minus 50 degrees), some used for high temperature cooking food bags can use the material;

Good oil resistance and fragrance performance is particularly outstanding;

Excellent barrier performance, blocking air performance, antioxidant, waterproof, moisture;

Good heat sealing performance, high softness;

The characteristics and advantages of aluminum foil food packaging bags

Made of aluminum foil made of food packaging bags to food non-toxic and tasteless, health and safety in line with national health standards.

Aluminum foil thickness is generally between 10-200 microns, according to different uses, the size of the packaging products made into different processes, aluminum foil food packaging as long as the process of three side sealed bags, self-reliance bags, zipper bags, Bags, yin and yang bags and other different processes.

haomei Aluminum foil - aluminum sheet is produced by cold-way and having a thickness of from 0.005 to 0.2 mm. Aluminum foil has excellent density, good water resistance and anti-air permeability, may also be exposed to high temperatures without deforming or melting, etc. therefore can be used in various fields of business, packaging, automotive and construction, etc. 

Quote:Household Aluminium Foil is used in a wide variety of applications because of its unique combination of properties and aluminium foil has been contributing to human comfort and health.
Strong and resistant for various applications in construction or transportation, easy to sterilize for medical uses, aluminium foil remains mainly the best packaging for food products and so on.

aluminium foil has unique deadfold characteristics which make it ideal for wrapping and re-wrapping many different products and product shapes, while minimising the need for sealants. Because it is very malleable it can be easily deformed without losing its barrier integrity, making it an ideal material for use in combination with other flexible substrates to create very thin laminates for a variety of markets and consequently, again, save resources.
