The 5182 aluminum coil belongs to Al-Mg-Si series alloy and has a wide range of applications. It is commonly used in automotive parts, can tab and can end. 5182 aluminum coil has good corrosion resistance, excellent weldability, good cold workability, and moderate strength. The main alloying element of 5182 aluminum alloy sheet is magnesium, and a small amount of silicon is added. Therefore, the welding performance of welding 5182 aluminum plate using gas welding, argon arc welding, spot welding and seam welding is very good.
In the aluminum roofing sheet factory or the application process, sometimes there will be the above black spot situation, what is this situation? Let’s look at it. First of all, the aluminum roofing sheet materials, aluminum roofing sheet manufacturers produced by the aluminum roofing sheet cover is 0.5mm thick LF21 aluminum plate processing. This type of aluminum roofing sheet has many parts of the same material, similar shape and same process, but similar shape parts processed at the same time have no such failure. And it’s not the fault of a defective raw material. It’s on the processing technology, cover silver plating process for roughly: outgoing parts machining pretreatment ─ ─ ─ ─ galvanized zinc leaching plating copper electroplating silver ─ ─ painting 823 ─ ─ dip coating into the Treasury.
Anodized aluminum plate is to place the Aluminum Plate in corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode for electrolysis under specific conditions with externally applied current. The Aluminum Plate of the anode is oxidized and has an aluminum oxide film formed on the surface; the film is 5-20μm thick, and a hard anodic oxidation film can be up to 60-200μm thick. After anodization,
The surface treatment of aluminum is a series of mechanical and chemical surface pretreatment processes in the process of surface film processing and combination. The surface pretreatment methods of aluminum are mechanical and chemical (or electrochemical). Mechanical methods include sand blasting, polishing, striping and polishing. The chemical method includes degreasing, alkali washing, light treatment and so on. The surface coating technology of aluminum mainly includes anodic oxidation, chemical transformation, electroplating, electroless plating and organic coating.
A gangway is an escalator that is installed on both sides of the ship for personnel to board or disembark. It is made of wood or metal. It consists of the upper and lower platforms, ladder frame, ladders step, railing handrail and lifting device, etc. When the ship is sailing, it is hoisted, folded and stored on the deck. When used, it is lowered and suspended from the side. Gangway installations are generally used for passenger ships and other types of large and medium-sized ships.
1100 aluminum sheet is industrial pure aluminum plate. It has small density and good plasticity. It is usually used for parts that require good forming performance, high corrosion resistance, and do not require high strength, such as sheet metal products, hollow hardware, radiators, and welding combinations keys, reflectors, nameplates, etc. So many customers want to purchase 1100 aluminum plate from China, then how to find reliable 1100
Henan is one of the aluminum processing industry gathering place, Henan aluminum manufacturers are numerous, all companies have differences in thequotations of aluminum, the buyer will be confused after consulting multiple manufacturers, the same alloy product prices how the gap is so large, thefollowing reasons several aspects:
5052 aluminum sheet is AL-Mg alloy aluminum alloy, which is the most widely used type of rust-proof aluminum. The strength of this alloy is high. In particular, it has anti-fatigue strength. It has high plasticity and corrosion resistance and can not be heat-treated and strengthened. It is semi-cold. The plasticity is still good when it is hardened, the plasticity is low when cold work is hardened, the corrosion resistance is good, the weldability is good, the cutting performance is bad, and it can be polished.
Almost all kinds of welding methods can used in aluminum sheet or aluminum alloy sheet , but different methods has its own application because of products adaptability
In fact, aluminum sheet is a kind of rectangular plate that use of aluminum ingots or aluminum rolling through a certain amount of processing, and aluminum alloy sheet is the upgrade products of aluminum, it add various alloy elements during processing, it aims to improve mechanical properties and chemical indicators. There are their difference performance:
