Why to Choose Aluminum Extrusion as Heat Sink Extrusions

Heat sink extrusions are taking up an increasing share of metal market all over the world, especially this year, when the winter seems to be colder in the Northern Hemishpere than previous years. It’s said that some colleagues in southern China have taken winter holidays in advance because of unusual coldness. Generally speaking, there are two types of heat sink extrusions in the market: steel and aluminum extrusions.

　　Although many people would like to choose steel for their, aluminum extrusions have obvious advantages over steel ones. First, they shows better heat dissipation property and are therefore more energy-saving. Less amount of aluminum heating plates are needed in the same room to reach the same heat dissipation effect. Second, aluminum heat sink extrusions prove to be more corrosion resistant than steel ones to which anti-rust additives must be added. The element of aluminum is so active that it produce a layer of oxide easily after being exposed to oxygen in the air. The layer, strong and dense, protects effectively the covered body against corrosive materials. Third, if you choose combined type of aluminum heat sink extrusions processed by high-pressure casting aluminum module, you will enjoy two bonuses. This type of plates have been pressure cast overall by a single process, and there will be no potential problems like water leakage when you use them. Besides, extra plates can be added directly to the original module if necessary, with no need of replacing the whole module as steel plates would have.
　　In spite of the advantages of aluminum heat sink extrusions above, customers should avoid to mix aluminum plates with those of other metals like steel, because they have different requirements for water quality. Haomei Aluminum supplies aluminum extrusions of varied specifications. Welcome to contact us at april@aluminumhm.com, leave a message below or wechat/whatsapp 008615838029491 for more information.

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
