Product Introduction

Aluminum Circle/Disc is mainly used for general commercial and industrial uses, like the capacitor case, toothpaste case, medical tubes, kitchen warespray bottle, cosmetic case and glue tube case etc. With high quality casting and rolling coils or hot rolled coils as raw materials, it goes through different  cold rolling deformation. slitting, annealing and finally stamping into an aluminum disc, then packaging for delivery.

Q:can the oxide film on the surface of aluminum sheet prevent the erosion of acid liquid? Why?
yes, acid can react with aluminum oxide , generating salt and water, but its anti-corrosion will be stronger if oxide film on the surface is enough dense.
Q:which kind of aluminum sheet could be bended after being etched?
general etching materials include stainless steel and copper.
Q:How to press multilayer aluminum sheets (aluminum sheet's thickness: 0.2mm) together and keep them inseperate after pressing?
resistance welding is a welding method that pressing the materials to be welded in an area between two poles and switching on current. the current will go through the contact surface and agjacent area, producing resistance heat effect which will heatthe materials into melting or plastic state and make the materials be welded together.
Q:what's the difference between aluminum sheet detergent and central air-condition detergent?
Central air condition cleaning includes air-cooled condenser cleaning and water-cooling condenser cleaning, if it’s air-cooled condenser cleaning, you can use aluminum sheet detergent.
Q:why does the hardness of 2024 aluminum sheet not increase but decrease after thermal treatment?
The hardness of 2024 aluminum sheet will decrease after thermal treatment(solution treatment), and it will increase after aging treatment.
Q:whst should I notice while welding aluminum sheet and aluminum block?
two types of aluminum reach melting points, aluminum block must be preheated when you weld them with small current, you will know how to do it. You can use argon-arc welding back and forth, preheat it with small current.
Q:Could induction heating fuenace be packaged with aluminum foil as insulation material?
It’s useless. Aluminum foil will generate eddy and emit heat after medium induction, which will reduce the thermal efficiency of medium frequency. Now I provide a method for reference only. Induction coil will be water cooling and is packaged by thermal cement and other materials. Use asbestos sheet and other materials to transform the both ends of induction heating coil as baffle which is mobile and convenient for load and unload. When steel tube is heated in the induction coil, you can put down the baffle to prevent large loss of heat, shorten heat time and improve heat efficiency. When the seamless steel tube is heated into setting temperature, you can open the baffle to conduct expanding process, and you don’t need to think about the thermorytic problem of steel tube in the expanding process. It’s important to shorten the time of expanding process. Baffle is used for heat retaining of medium frequency heating and extrusion forming in our factory. The method above for reference only.
Q:how to produce aluminium sheet circle?
As for the process, you can use punch.. as for professional machines, for example, stationary press in open type, mechanical press/ single-point press. The material you say is neither big nor small, blanking…(cutting them into sheet circle you want) you can add an uncoiling if it’s coil stock: open-type inclinable press, four-point press,ect. It’s not certainly accurate) punch, oil press, double , four-column hydraulic (oil) press,etc. it needs about 315T,(estimated value, closed type single, blank material cutting (cutting into square ) 2, it contains sheet metal forming technology, crank press: 1: straight side two : 1, but the components you said is simple, only two steps.
Q:after putting aluminum sheet into the area between magnet and iron products, could magnet attract iron again?
magnet can attract iron if the aluminum sheet isn't too thick. Because aluminum can't cut off magnetic line of force, unless aluminum sheet's thickness surpass the range of magnetic attraction.
Q:has aluminum sheet reacted with concentrated sulfuric acid?
it can be regarded as no reaction, concentrated sulfuric acid will make aluminum's surface inactivation,and produce a layer of dense aluminium oxide film which will prevent further reaction.
