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:What are the effects of casting temperature on ductility of aluminum coil?
The tensile strength and ductility increase with the solid solution insulation time, and reach best fit at 1 hour. Continue thermal insulation, and the tensile strength will change little while the ductility will reduce. This is because the solid solution over insulation will cause the work pieces crystallize so that the large crystal reduce the plasticity.
Q:What are the best rust-proof coils? Please tell me the model and manufacturer in Shangdong. Thank you.
3003 aluminum coil, AL-Mn series alloy, is the most widely used rust-proof aluminum with the density being 2.73. It is applicable to insulation projects such as pipe insulation, packaging, machine parts, refrigerator, air conditioning and ventilation pipes and other wet environment.
Q:How much is the rust-proof and thermal insulation aluminum coil?
3003 alumal alloy is the best and common rust-proof and thermal insulation aluminum coil. The price depends on the thickness and width you need.
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: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.
If it is 1.0mm thick, the coil can be sliced into 124 pieces. For other thickness, please use 124 divide the thickness.
Q:Why there is always impression and indentation on the backup roller of aluminum coil rolling mill with 4 rollers.
It is either the external or the bearing problem in designing and installing.
Q:Why does the end face of aluminum coil have grease spots?
The reason may be that the manufacturer hasn’t cleaned. Before being coated, the aluminum should be cleaned carefully. Otherwise the paint will peel off.
