1060 Aluminum Strip for Transformer Winding Features

The 1060 aluminum strip for transformer winding is divided into different grades, specifications and states. The grades are 1060, 1050, 1050A, 1060, 1070, 1070A and 1350, and the state is mainly O which represents a soft state, and the degree of hardness. The degree of annealing can be indicated by numbers. With a thickness between 0.08 and 3.00, the 1060 aluminum strip for transformer is also called aluminum tape and foil for dry transformers.
1060 aluminum strip for transformer winding
　　1060 aluminum strip, which contains more than 99.6% aluminum, is also called pure aluminum strip. It belongs to a common series in the aluminum strip family. The aluminum ribbon and foil for dry-type transformers are made of high-quality pure aluminum. They have a high electrical conductivity and a soft texture. The surface is smooth and burr-free. As an ideal material for the production of dry-type transformers and a key raw material for manufacturing transformer winding, its production entail high process technologies in burr curling, side bending and surface quality.
　　The 1060 aluminum strip for transformer is made of pure aluminum. Pure aluminum has a low density (ρ=2.7g/cm3), about 1/3 of iron, and has a low melting point (660°C). Aluminum is a face-centered cubic structure, so it has a high plasticity (δ: 32~40%, ψ: 70~90%), easy to process, can be made into various profiles and plates, good corrosion resistance; but the strength of pure aluminum is very low, the annealing state σb value is about 8kgf/mm2, so it is not suitable for structural materials. The price of 1060 aluminum strip is about 20 yuan and 1 kilogram. According to the annealing state of the aluminum strip, the aluminum strip can be divided into full soft (o state) semi-hard (H24) full hard (h18). At present, the most commonly used ones should belong to the all-soft series, because the O-state is easier to stretch and bend. The general specifications are: thickness 0.05, 0.1, 0.15, 0.2, 0.3, 0.5, etc. Normal width include 50, 60, 80, 100, 120, 150, 300, etc. Of course, there is also a whole piece of aluminum foil, such as 0.1*1000* 2000, that is 0.1mm thick, 1000mm wide, 2000mm long.

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,...
