Characteristics and Application of 7005 Aluminum Coil Alloy

7005 aluminum coil

The strength of 7005 aluminum coil alloy is higher than 7003 alloy, which features good welding performance and good heat treatment. 7005 Aluminum Roll Alloy extrusion material, often used in making welded structure which requires high strength and high fracture toughness, such as transport vehicles, truss rod, container; large heat exchanger, also can be used in the manufacture of sports equipment such as tennis and softball bar.
Lightweight is the development trend of modern transportation industry. And it means that the lightweight materials is widely used in vehicles. 7xxx Aluminum Roll Alloy belongs to high strength Aluminum Alloy. Characteristic with low density, high strength, good performance and good welding performance of extrusion,. With these advantages, 7xxx series aluminum alloy can be regarded as the key materials for high speed train, subway, light rail train and double deck train and luxury buses and other modern transportation tool. 7005 Aluminum Coil Alloy which belongs to Al-Zn-Mg-Cu system can be strengthened by heat treatment of high strength Aluminum Alloy. Including high strength, fracture toughness, high corrosion resistance and thermal stability, and good performance of extrusion, 7005 Aluminum Roll Alloy has gradually become one of the main timber large Aluminum Alloy profile for vehicle. Because of the instability of forming properties of high strength aluminum alloy, how to improve the formability of aluminum alloy profile has become one of the focuses of research at home and abroad.

What is The Pharmaceutical Packaging Aluminum Foil-PTP Aluminum Foil

图片
PTP Aluminum Foil PTP is the abbreviation of Press Through Packaging, which is translated as “through the pressure packaging”. Its formal title is the pharmaceutical packaging aluminum foil, also known as blister packaging aluminum foil. European PTP aluminum foil in English is Push-through Foil. China’s   PTP aluminum foil   in the pharmaceutical packaging materials, container registration card on the use of the title is: pharmaceutical packaging with PTP aluminum foil. Medicinal blister packaging materials are basically aluminum foil. Because the drugs is packaged by PTP aluminum foil, which features contents can be clearly visible. The aluminum foil surface can be printed by new design style, which is easy to identify patterns and trademarks. At the same time the barrier performance PTP aluminum foil is very good, which features light weight, with a certain intensity, easy to be crushed, and convenient to store the strugs, and easy to carry.

How to prevent the aluminum coil from corroded

图片
It is all known that in the current market, aluminum coil is widely used in aluminum-plastic panels, aluminum ceilings, fire plywood, garage doors and other products in the production, but there are some shortcomings, that is, if we do not pay attention to protect for a long time, there will be corrosion phenomenon, how can we prevent the aluminum coil form corroded effectively? Let us learn about it together, there are some suggestion from Haomei aluminum: (1) If the workshop, warehouse roof is leaking rain and snow, then the aluminum coil should not be placed at here. (2) The worker should strengthen the management of air drying to ensure that the compressed air without water. (3) The aluminum coil packaging should adopt sealed packaging, and each volume should be placed in some amount of desiccant. (4) If the aluminum coil is transfer from the low temperature area into the high temperature, humidity areas, do not immediately open the sealed package. (5) The
