Nine series of aluminum coils—-CAMELSTEEL Knowledge Base
Last time, the first five series of aluminum coils explain, so today let us take a look at the four major series under us.
6. 6000 series
It represents 6061 mainly containing magnesium and silicon, so the advantages of 4000 series and 5000 series concentrated,
6061 is a cold-treated aluminum forging product, suitable for applications with high requirements for corrosion resistance and oxidation.
Good workability, excellent interface characteristics, easy coating, and good processability. It can be used on low-pressure weapons and aircraft joints.
6061’s general characteristics: excellent interface characteristics, easy coating, high strength, good workability, strong corrosion resistance.
Typical uses of 6061 aluminum: aircraft parts, camera parts, couplers, ship parts and hardware, electronic parts and connectors, decorative or various hardware.
Of course, there are hinge heads, magnetic heads, brake pistons, hydraulic pistons, electrical parts, valves, and valve parts.
7000 series represents 7075, which mainly contains zinc.
It also belongs to the aviation series.
It is an aluminum-magnesium-zinc-copper alloy, a heat-treatable alloy, and a super hard aluminum alloy with good wear resistance.
The 7075 aluminum plate is stress-relieved and will not deform or warp after processing.
All super All the thick 7075 aluminum plates ultrasonically detected, which can ensure no blisters and impurities.
The high thermal conductivity of 7075 aluminum plates can shorten the molding time and improve work efficiency.
The main feature is that the hardness of 7075 is a high-hardness, high-strength aluminum alloy, which often uses in the manufacture of aircraft structures and futures.
It requires the manufacture of high-stress structural parts and molds with high strength and strong corrosion resistance.
At present, basically relying on imports, my country’s production technology needs to be improved.
(The company once proposed that the domestic 7075 aluminum sheet not uniformly annealed, and the surface and internal hardness of the aluminum sheet are inconsistent.)
The more commonly used 8011 belongs to other series.
In my memory, the aluminum plate whose main function is to make bottle caps also used in radiators, most of which are aluminum foil. Not very commonly used.
It is a spare series. The technology is so advanced now.
In order to cope with the emergence of aluminum plates containing other alloy elements,
the International Aluminum Strip Federation has indicated that the 9000 series is a spare series, waiting for another new variety to appear to fill the gap of the 9000 series.
