Aluminium Sheet Mirror Finish Used in Flash Lights

As known to all, lighting is a primary industry applying aluminium sheet mirror finish. Speaking of lighting, we think of street lights, commercial lights and domestic lamps. Has it ever occurred to you that flash lights also belong to the huge lighting family? As a matter of fact, people began using flash lights as early as 1887, only decades later than that of bulbs. The earliest flash lights were actually only burning materials (mixture of magnesium and potassium chlorate) that turned into ash after their mission was done. Nowadays you can find flash lights of various designs and materials in the market, some of which adopts aluminium sheet mirror finish as a component.

Boasting excellent reflective rate, mirror finish aluminium sheet is applied as reflective cover of flash lights. The sheet is suitable for diverse process methods. While some sheets are of smooth mirror surface, others are embossed to meet special photographing requirements. Installed around the flash bulb, the sheet functions to increase brightness of targets to be photoed. Generally it improves light reflectivity by 80% and above. As other aluminum products, mirror finish aluminium sheet has an advantage of low weight over other candidate metals. Its density is only one third of that of iron, not to mention copper. That means an aluminium reflective cover weighs only 30% of a stainless steel one of the same volume, which enables photographs to move the flash light more effortlessly. What’s more, aluminium sheet mirror finish is of lower price than other metal products, thus flash light manufacturers are willing to reduce cost by choosing it as raw material.

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 ...

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,...
