Are lamp covers made of 1xxx or 3xxx aluminum circle blanks

 As known to all, 1xxx and 3xxx are the most popular of aluminum circle blanks. These are further made into cookware, lamp covers and other products needing deep drawing or spinning before coming into being. Which alloys, then, are suitable as lamp cover materials?

The most frequently applied aluminum circles of 1000 series proves to be 1050, which can be substituted by 1060 in case of material shortage, for the two share equivalent properties. 1050 incorporates 99.% aluminium and 0.5% other metals. Owing to high content of aluminium, 1050 is known as a member of pure industrial aluminium group, characterized by low hardness, high plasticity and excellent elongation. Generally speaking, low strength of aluminium alloys accompanies good tensile strength and elongation, necessary conditions for deep drawing and spinning. That’s why 1050, 1060, 1070 and 1100 aluminium grades rank top in aluminium discs blank products. They have the best plasticity. In comparison with 3xxx circles, they have poorer corrosion resistance, but still prove to be a widely applied aluminum circle for lamp cover.

3xxx aluminum circle blanks are stronger in both hardness and corrosion resistance. The representative is 3003 DC aluminum disc. 3003 is harder and more erosion resistant because it contains an alloy metal of manganese. The 1.0% to 1.5% manganese greatly improves mechanical and chemical properties of 3003. This can be used in lamp covers, too, but in those requiring higher weather resistance and longer service life. Sometime 3xxx aluminium wafers are anodized to obtain better surface quality, but their anodizing effect is not so good as 5xxx circles like 5052.

To sum up, both 1xxx and 3xxx aluminium discs blank can be applied in lamp covers, but the latter has better performances. Purchasers can choose suitable alloys based on their actual needs.

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,...
