Application of aluminium circle sheet

    　The aluminum circle sheet pieces are widely used in electronics, daily chemicals, medicine, culture and education, auto parts, electrical, thermal insulation, machinery manufacturing, automotive, aerospace, military, mold, construction, printing and other industries. The main application industries are kitchen utensils and lamps, such as non-stick pans, pressure cookers, lampshades, water heater casings etc.. The aluminium circle sheet is one of the largest aluminum alloy sheet and strip deep processing products.

    　　Aluminium circles have good thermal and electrical conductivity. The thermal conductivity of high-purity aluminum which is completely annealed at 0~27°C is 2.367W/(CM·K); the resistivity of ultra-purple aluminum (99.990%) at 20°C It is 2.6548×10-8 Ω·m, which is 64.94% IACS (International Annealed Copper Standard). The good electrical conductivity of aluminum combined with low density makes it a good long-distance transmission conductor. In notebook computers and many electronic devices, there are some components made of aluminum circle sheets, each of which plays an indispensable role. The heat dissipating components utilize the good thermal conductivity and low density of aluminum.
    　　The aluminium circle sheet has a superior corrosion resistance. The aluminum disc and the surface of the aluminum alloy have a layer of aluminum oxide film which is incomparably thinner than the flap. This is a natural oxide film formed by oxygen in the air. The thickness of the film formed at room temperature is 2.5. ~3.0nm25~30A). This film is not only thin and surprising, but also extremely dense, can not penetrate oxygen, and is firmly bonded to the aluminum wafer, so that the aluminum wafer is no longer subject to corrosion, that is, it will not be reoxidized, so that the aluminum wafer and the aluminum alloy are After the expiration of the service period, more than 95% of the recycled aluminum can be obtained after treatment and remelting. Excellent performances make aluminium circle discs a regular industrial raw material.

Slitting of 1mm 2mm 4mm aluminium strip

图片
What kind of machine is used to make aluminum sheets into 1mm 2mm 4mm aluminium strip belts? Many people might think about a shearing device, but they are actually dealt with by a continuous slitting unit of a similar working principle to that of a shearing device. The difference lies in the point that there is no pause of shearing with a continuous slitting unit. Generally, the mother roll, namely, an  aluminum coil  to be slit, is placed. During the slitting process, the coil roll is divided into several belts which are further rolled into narrow aluminium strip rolls. The slitting method of both  1mm 2mm 4mm aluminium strip  or other aluminum strips can be divided into two types: a straight pull type and a loose sleeve type. The straight pull type refers to the method that aluminum strip rolls are kept in tension from being fed into the unwinding sail to being coiled by the coiling machine, and this production method is suitable for trimming and intermediate ...

Diamond Embossed Aluminum Sheet Application

The  diamond embossed aluminum sheet  refers to aluminium sheets with diamond patterns on the surface. In addition to 1000 series, 5005 and 3003 are frequently applied alloys as well. 5005  diamond embossed aluminum sheet s can be used for conductivity materials, cookware, instrument panels, electronic shells and building ornaments. Their anodized film proves to be brighter than that of 3003, and the color matches perfectly with that of 6063 aluminum alloy products. Generally speaking,  diamond aluminum checker plate s are sold by the unit of pieces. In international business the unit of metric ton is frequently used as well. Their thickness ranges from 1.7mm to 8mm, but those between 2mm and 7.75mm prove to be the most popular. The width is from 1010 to 1500, among which 1250 and 1500 are most frequently adopted. Embossed aluminum sheet s with different patterns usually match varied application scope. Five-bar and one-bar sheets are mostly used for anti-skid pu...

Embossed Aluminium Coil Patterns And Applications

图片
If you have ever used an escalator you might have noticed that there are partition panels respectively at the bottom and top of the escalator. These partitions are usually paved with  embossed aluminium sheet  coil that have a good pressure bearing capacity and are made of composite metals. As a matter of fact, there are various patterns and applications of embossed aluminium coil, and here we will give a simple introduction. 　　Patterns 　　Aluminum sheets with patterns on the surface is called embossed aluminum sheets or  aluminium tread plate . Pattern shapes include lentils, diamonds, round beans, and oblate mixed shapes. The market is most common in lentils. 　　Application 　　The aluminium tread plate has beautiful appearance, excellent anti-slip property, enhanced performances, and material-saving advantage in production. It is widely used in transportation, construction, decoration, equipment, floor, machinery, shipbuilding and other fields. Generally speaking,...
