Cans cover (ring) pre-coated plates
First, the raw materials
Aluminum lid and pull the main substrate of aluminum from the southwest andNanshan Aluminum, the use of aluminum-magnesium alloy 5182H19, 5052H19. Itsproducts in the normal substrates of manganese and magnesium components addedto increase the tensile strength and elongation. Han and the lotion by theGerman food-grade chrome HD agent, the United States PPG epoxy phenolicpackaging coatings, and high-end DOS oil
Second, applications
Division I professional production of DOS card and aluminum cans with a coatingfor cans of the lid and pull the coated aluminum is widely used in beverage,beer, rice pudding, tea, cigarettes, cans and other products packaging. U.S.imports of food ash using electrostatic spray wax, cut by large waves, transverseshear, longitudinal easily processed into the system covered the pre-coatedaluminum manufacturers. Depending on the system covers equipment can makeweight and volume of different specifications to meet customer requirements.
Third, the application prospect
Cans of food packaging as lightweight, unbreakable, easy to carry transportcharacteristics, cans packaged foods will gradually replace the glass packagingfood. As

- Q:wikipedia says welding aluminum by means of stick welding is possible but i have always been told TIG is the only way to weld aluminum. what do i need in order to stick weld aluminum? BTW i have a Lincoln Electric AC 225 Stick Welder
- Stick Welding Aluminum
- Q:Aluminum extrusions are bars made with hollow cavities that allow each to be joined easily, using special connectors. The primary difficulty when painting aluminum extrusions centers on the fact that they are nonporous and durable. Each of these traits creates a complication of its own.
- Your question supposes that you need to Paint the Aluminum Extrusion. The more common thing to do is to Anodize the extrusion. This process coats all surfaces with a hard durable coating. There are several colors available. Actually It's common to use Urethane's to paint Aluminum and the primer isn't simply made for metal, but is specifically for Aluminum. A lot of Airplanes are coated every day in this manner. Methods for coating the insides of tubing have been used for a very long time. You basically fill the tube with primer or coating then drain the excess out (dip method) and difficult shapes can be powder coated or electro static coated. Extrusions can be roller coated after cleaning, vinyls work very well with out priming. Think Toothpaste tubes.
- Q:What’s the standard of tensile strength and ductility of aluminum coil 3003?
- Detailed description can help resolve problems quickly. Performance and status is a related. As aluminum coil is usually semi-hard, the tensile strength is greater than or equals 150, ductility is greater than or equals 12.
- Q:In my line of work I see aluminum ground lugs, bonding nuts and straps and also neutral bars eat copper up, especially when exposed to the elements. I know how galvanic reaction works between elements under current load, but my question is why do aluminum and copper seem to hate each other more than any other? And, why would they still be required in usage together per NEC code?
- that's a single alternative reaction. The aluminum and the copper swap places, yielding copper and aluminum sulfate. Please notice: the 1st answer describes a chemical equation with nitrate, no longer sulfate. otherwise, this is the perfect format.
- Q:1mm how much is one square meter for aluminum rolls?
- The price of aluminum sheet is calculated according to the price of aluminum ingot + processing fee (aluminum plate state), and the specific price is also different according to the size and size of aluminum sheet.
- Q:just wondering if you can weld aluminum pipe to a metal pipe for a cars exuast
- i don't see why not becasue volvo uses aluminum exhaust systems.
- Q:How much is a ton gate of Jiangxi aluminium roll?
- Roll gate installation guide and measurement:The height h (the ground to the top of the doorway height);The table width (the distance between left to right, generally can be divided into single, double, three car garage);H (the height of lintel beam bottom to the height of the ceiling. If there is a beam or stringer in the room, it should be calculated as the distance between the top of the hole and the beam;
- Q:I need to lay down two 3 welds on some 1/8 aluminum but my welder is not set up for it. could i just out fit my welder with aluminum wire without buying the spool gun and get the same results? or maybe I should just get a welding shop to do it for me?
- What is your machine that you will be using? Can you weld AC on it? Do you have a High Freq. Box? Will you GTAW it or use GMAW? What Alloy of Aluminum is it? Need much more info than you have provided. If GMAW best to have a pull or a push / pull wire feed system such as in a spool gun. Aluminum is too soft to just push from a wire feeder unit.
- Q:How many companies have used aluminum coil?
- Too many. All the companies who make the aluminum products you have seen in daily life have used it. So it is hard to explain.
- Q:Should the aluminum roll be in the direction of the aluminum roll length or width?
- Should the aluminum roll be in the direction of the aluminum roll length or width?The width of the road shall not be less than 1.5 times the width of the standard vehicle, and the width of the carriageway shall be at least 7.0M, and the lane shall not be narrower than 4.0M. (County Road, the main road on the standard)As the national standard does not specify the upper limit of the total width of the road, it only specifies the width of the minimum Lane corresponding to different grades of highways.
