Features and usages of 5052 aluminium metal strips

The main alloying element of 5052 aluminium metal strips is magnesium, which has good forming and processing properties, corrosion resistance, weldability and medium strength. 5052 aluminium metal strips are used as raw materials for aircraft fuel tanks and oil pipes, sheet metal parts for transportation vehicles and ships, instruments and street lamp brackets, hardware and electrical enclosures etc.
This is a picture of aluminium metal strips.
5052 aluminium strips are of Al-Mg rust-proof aluminum. Compared with 3A21, 5052 has a higher strength, especially high fatigue strength. Similar to 3A21, it has high plasticity and corrosion resistance. It cannot be strengthened by heat treatment, and is suitable for contact welding and Hydrogen atom welding has good weldability, but there is a tendency of crystal cracking during argon arc welding.
Mechanical properties of 5052 aluminium metal strips:
Tensile strength σb (MPa): ≤225
Elongationδ5 (%): ≥10
Specimen size: bar diameter (square bar, hexagonal bar inscribed circle diameter) ≤ 150
Heat treatment specification of 5052 aluminium strips
1. Homogenization annealing: heating 440oC; holding 12 ~ 14 h; air cooling.
2. rapid annealing: heating 350 ~ 410oC; holding time 30 ~ 120min; empty or water cooled.
3. high temperature annealing: heating 350 ~ 420oC; finished product thickness ≥ 6mm or <6mm, holding time is 2 ~ 10min or 10 ~ 30min; air cooling.
4. low temperature annealing: heating 250 ~ 300oC or 150 ~ 180oC; holding time is 1 ~ 2h, air cooling.

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

图片
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,...
