Product Description:

Aluminium is a relatively soft, durable, lightweight, ductile and malleablemetal with appearance ranging from silvery to dull gray, depending on the surface roughness. It is nonmagnetic and does not easily ignite. A fresh film of aluminium serves as a good reflector (approximately 92%) of visible light and an excellent reflector (as much as 98%) of medium and far infrared radiation. The yield strength of pure aluminium is 7–11 MPa, while aluminium alloys have yield strengths ranging from 200 MPa to 600 MPa. Aluminium has about one-third the density and stiffness of steel. It is easily machined, cast, drawn and extruded.

Q:Is aluminum veneer the same as color coated aluminum coil?
In general, the molded product will be painted by special spraying factory according to customer’s needs. Color coated aluminum coil is more popular in ceiling.
Q:Will the surface of aluminum contact water if the aluminum coil falls into water?
Yes.
Q:Why does the coated aluminum coil have thickness requirement for membrane?
The purpose of coating is to protect the surface of aluminum coil and make it more aesthetic. The thickness of membrane is closely related to the keep years of products made by aluminum coil.
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 5052 turn black after annealing during the production of aluminum alloy?
It has been sooted.
Q:If the aluminum coil is 220 kg, 0.3 thick and 500 wide, how much is the coil diameter?
With the outer diameter and inner diameter, you can know the volume. With the density and volume, we can calculate the weight. And with weight, we can know the length.
Q:Can aluminum foil coil be stores for a long time?
It is ok within one or two years, but for five or six years, it will be oxidized.
Q:What is the formula to calculate the wall thickness of aluminum coil?
Aluminum coil thickness*aluminum coil width*aluminum coil curl*aluminum density (the density of aluminum alloy: 2.73, the density of pure aluminum: 2.71)
Q:Why the aluminum sheet crack after?
Maybe the crack existed during welding but you didn’t notice. And then it expands and becomes obvious when acted on by external force in circling process. The reason may be the welding craft. Besides, I suggest more comprehensive tests after welding, such as penetrant test.
Q:How to remove the fingerprint and glue residue on the color aluminum coil?
Try to use essential balm. We often use the essential balm to remove glue residue on the stainless steel bowl and basin.
