<strong>Flat aluminum strips</strong> are widely used in industrial area, so they have strict quality requirements on the specification, surface, edge and performance. The thickness should be uniform, the width should be uniform, no color difference, no wrinkles, discounts, no cracks, burrs, at the edges. The end face is neat and free of channeling.</p>
<br><p>
The common terms for flat aluminium strips are:<br>
Diagonal: the diagonal tolerance of aluminum strips. Generally speaking, the diagonal tolerance of <strong>flat aluminium strip</strong> cannot be greater than 2 mm, otherwise it will deform.<br>
Thickness tolerance: During the production process, there will be a certain gap in the thickness of flat aluminum strips. According to the requirements, the thickness tolerance of aluminum strips is usually within 0.8-1.0 mm (determined according to the thickness of aluminum strips).<br>
Length and width tolerance: The gap between the length and width of aluminum strip during the production process is usually implemented according to international standards.<br>
Tensile strength: that is, the hardness of the aluminum strip. The higher the tensile strength of the aluminum strip products, the greater the hardness and the smaller the elongation.<br>
Elongation: It reflects the range of use of <strong>flat aluminum strips</strong>. Under normal conditions, the aluminium strips has the largest elongation and is suitable for deep drawing products.</p>

The <strong>conductive aluminum foil tape</strong> for transformer is aluminum strip material 1060 and 1070 o soft temper, the thickness 0.2-3.0mm, the width is 100-1200mm. Because the conductivity of aluminum strip material is next to that of copper, and its cost is low, aluminum foil strip material gradually replaces copper as the main raw material of international electronic products.</p>
<br><br><br><p>
The high-voltage winding is wound by aluminum foil tape and high-quality insulation foil. The wire coil is placed in a heating mold and poured in a vacuum tank with a special proportion of resin. Vacuum casting exhausts the gas from the windings to ensure low partial discharge of the transformer. Because the thermal expansion coefficient of conductive <strong>aluminum strip</strong> and the casting resin is very similar, the thermal stress caused by load changes is kept to a minimum, which improves the winding's crack resistance. Foil windings combine simple technology with a high degree of electrical safety. Compared to other types of windings, insulation withstands less electrical stress. In conventional round wire windings, the inter-turn voltage can reach twice the inter-layer voltage. A layer of aluminum foil winding has only one turn, so the electrical stress is kept constant, and the winding can withstand high power frequency voltage and surge voltage.</p>
<br><p>
The dielectric stress of the low-voltage winding is small. This type of winding is made of a single sheet of <strong>conductive aluminum foil tape</strong> or copper foil with a resin-impregnated glass fiber cloth insulation in the middle.</p>

To purchase high quality <strong>aluminium strip 50mm</strong>, Haomei is your best choice, the thickness could be 0.02-4mm, which has wide application. We all know that the metal is easy to be oxidized, which has been a headache in the application of metal industry. Especially in the three metals of iron, aluminum and copper, which are commonly used by us, many users of aluminium strip do not know how to deal with this situation. Today we will talk about how to prevent the oxidation of 50mm aluminum strip.<br><br></p>
<br><p>
The first is to catch the source of moister. After the production of aluminum strip, let the aluminum strip cool down to the external temperature, and then pack the <strong>aluminium strip</strong> product. The best way is to use plastic bags to take the whole aluminum strip coil. All packages are tight. After packing, put several bags of desiccant into them.<br>
Second, try to avoid rainy weather during transportation. If it rains, the aluminium strip 50mm should be covered with tarpaulins to prevent rain from entering.<br>
The third point: after the aluminum strip are unloaded, go to the aluminum strip distributors or customers, and remember that the warehouse must be well ventilated, with high terrain, and the ceiling shall not leak, and the sewer shall be kept open to prevent heavy rain and heavy rain.<br>
The fourth point: in the use process, if the package is disassembled, the <strong>aluminium strip 50mm</strong> can be used once, and the package must be reapplied, but in the middle of the interval, there is usually no problem.</p>
