Aluminium sheet grades

 Haomei supplies 8 series of aluminium sheet grades as below.

1xxx grade: 1050, 1060, 1070, 1100

The aluminium content of these are respectively 99.5%, 99.6%, 99.7% and 99%. 1xxx is the softest and most vulnerable to rust of all grades, used in cookware, electronic units, decorative objects etc.

2xxx grade: 2A06, 2A10, 2A12, 2A16, 2014, 2017, 2024, 2124, 2224, 2524

Also known as an aircraft grade aluminum sheet metal grade, 2000 aluminum sheets are characterized by high hardness, among which the copper content is the highest, about 3-5%.

3xxx grade: 3003, 3004, 3105, 3104, 3A21, 3104, 3005

3000 aluminum plates take manganese as the main component, and the content is between 1.0-1.5%. The anti-rust function is better than 1xxx and can be used in the humid environment of conventional industries, such as building decoration industry, electronic manufacturing industry, automobile manufacturing industry, etc. The color coated 3003 and 3004 aluminum sheets are a high-quality roofing material of houses and vehicles, while coated 3104 and 3105 sheets serve as beverage can materials.

The 4 series aluminum plate is an aluminum-silicon alloy, which has the characteristics of high strength, good wear resistance, low thermal expansion coefficient, and easy casting. It is the most ideal material for manufacturing automobile and motorcycle internal combustion engine pistons.

5xxx grade: 5052、5005、5083、5A05

These are usually used in anti-rust conditions for vehicles, marine building etc. The main element of 5000 aluminum plates is magnesium, and the magnesium content is between 3-5%. 5xxx sheets are a regular material for aluminium tread plate. The main features are low density, high tensile strength, high elongation, and good oxidation performance. Anodized 5005, 5052 and 5083 aluminium can be made into cell phone shells.

6xxx grade: 6061, 6063, 6082, 6005, 6060, 6005A, 6101

6xxx aluminum sheets are cold-treated forged products, which mainly contain magnesium and silicon. They have much higher corrosion and oxidation resistance than 5xxx, and have extremely high toughness. Commonly used in aluminum checker plates, precision instrument parts, hardware, pistons, valve parts, molds, etc.

7xxx grade: 7075, 7005, 7050, 7A04, 7A09

As a heat-treatable alloy of aluminum-magnesium-zinc-copper, 7xxx is the other aircraft aluminium grade in addition to 2xxx. Among the 8 aluminum sheet series, the 7 series aluminum plate is among the best in hardness, wear resistance, and corrosion resistance. It is used for high-stress structural parts and mold manufacturing.

8xxx grade: 8011

8xxx grade aluminium is more frequently made into rolls rather than sheets. 8011 aluminium sheet is made into ropp caps and gaskets.

 

Aluminium sheet grades are classified by the alloyed metals, and each grade are further divided into varied alloys with differed properties and applications. Mastering them will be a long arduous journey.

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,...
