Q:How to calculate the length of aluminum sheet with the thickness known?
Thickness*width*length=weight/density, length=weight/(density*thickness*width). Ps: Keep unit the same.
Q:What are the differences between aluminum coil 3003h24 and 3a21h14?
The mechanical property references of rolled plate 3003 H24and 3A21 H14 are as follows: 3003 H24--Rm/MPa≧140-180;Rp0.2/MPa≧115;A(%)≧1-5(thickness 0.2mm-4.5mm)3A12 H14--Rm/MPa≧145-215;A(%)≧6
Q:How much cube is the 0.9mm aluminum rolling?
This is a common problem. Anyone who had received high school education can calculate it very quickily. One way is to calculate sectional area with circular area, then times the thickness of the aluminum rolling. Another way is to use the outer diameter circular area to subtract the core area and then times the thickness of aluminum rolling.
Q:How does aluminum ingot be processed to aluminum coil (aluminum sheet)?
First it should be made into blank and then put on the rolling mill.
Q:Can the 5-10cm thick paper sleeve inside the scrapped aluminum coil be sliced? Now we use knife which is much troublesome.
You can use Long Men Rolling Mill to slice directly.
Q:The specification of thermal insulating aluminum coil
4-0 In general, the chemical engineering products for thermal insulation is 0. According to the International standard, the thickness tolerance is +-5%.02MM. according to industrial standard, it is +-0. The production crafts are embossed and plain sheet.
Q:How is the welding performance of 3003 aluminum coil?
3003 aluminum coil, a kind of rust-proof aluminum, belongs to AL-Mn series alloy. With low intensity (slightly higher than commercial purity aluminum), it cannot endure heat treatment, so cold processing is adopted to increase its mechanical property: high plasticity in annealing and semi-cold hardening, low plasticity in cold hardening, good corrosion resistance., good weldability and bad machinability. It is mainly used for low load part in liquid or gaseous medium requiring high plasticity and good weldability, such as fuel tanks, gasoline or lubricant conduit. It can also be used for liquid containers and other deep drawing small load parts made by deep drawing. Aluminum wire can be used to make the rivet.3003 aluminum sheet has good formability, weldability and corrosion resistance. It is used to process parts which require good formability, corrosion resistance and weldability and lower intensity than 1xxx series alloy, such as such as kitchenware, food and chemical products processing and storage equipment, groove and tank to transport liquid product, pressure vessel and pipe processed from thin plate, cooling fin, make-up board, photocopier rollers and ship material.
Q:How to calculate the dosage of paint for aluminum coil coating? If the weight is 1 ton, the density 2.71 and the thickness 0.12mm, how much paint is needed?
Coating surface area S*0.12(thickness)*ρ(density) / solid(paint solid)=actual paint consumption brush and roller paint: 100% spray paint: calculated value*70%
Q:Why the aluminum sheet crack after?
What I want to add is to choose such welding wires as 5383 or 5183 wire whose magnesium content is higher than 5754 wire. The loss of magnesium due to high temperature in welding process may reduce the intensity of welding area.
Q:How many 1220mm*2440mm aluminum sheets can one-ton aluminum coil be sliced to? Thank you.
You should know the thickness of aluminum sheet first, and then calculate the weight of aluminum sheet of this specification, and finally use 1T divide the weight.
