Product Description:

Aluminium is a relatively soft, durable, lightweight, ductileand malleablemetalwith appearance ranging from silvery to dull gray, depending on the surfaceroughness. It is nonmagnetic and does not easily ignite. A fresh film ofaluminium serves as a good reflector (approximately 92%) of visible lightand an excellent reflector (as much as 98%) of medium and far infraredradiation. The yield strength of pure aluminium is 7–11 MPa,while aluminium alloys have yield strengths ranging from200 MPa to 600 MPa. Aluminium has about one-third the densityand stiffness of steel. It is easily machined,cast, drawn and extruded.

Aluminium alloys (or aluminum alloys; see spellingdifferences) are alloysin which aluminium(Al) is the predominant metal. The typical alloying elements are copper, magnesium,manganese,silicon,tin and zinc. There are twoprincipal classifications, namely casting alloys and wrought alloys, both of which are furthersubdivided into the categories heat-treatableand non-heat-treatable. About 85% of aluminium is used for wrought products,for example rolled plate, foils and extrusions.Cast aluminium alloys yield cost-effective products due to the low meltingpoint, although they generally have lower tensile strengthsthan wrought alloys. The most important cast aluminium alloy system is Al–Si,where the high levels of silicon (4.0–13%) contribute to give good castingcharacteristics. Aluminium alloys are widely used in engineering structures andcomponents where light weight or corrosion resistance is required

Q:How much is aluminum-plastic panel with the 0.155mm thick aluminum per ton?
The price is around 17000 yuan per ton, but you need to take the surface effect into account
Q:How to sell the super hard 5083aluminum alloy and 5083 aluminum coil?
Among the alloy which cannot endure heat treatment, 5083 aluminum alloy, a kind of high magnesium alloy, has the properties of intensity, machinability, anti-corrosion, electric-arc weldability and aesthetic after anodizing. The main element of 5083 alloy being magnesium, it is endowed with corrosion resistance, weldablility and moderate intensity, thus applicable to maritime areas such as ships, and cars, airplane weldments, metro light rail, and pressure vessel (such as liquid tank truck, refrigerated truck, refrigerated container), refrigerating equipment, television tower, drilling equipment, transport facility, missile parts, armor and so on.
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: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:Why 5052 turn black after annealing during the production of aluminum alloy?
The aluminum oxide in the surface has been oxidized by other chemical elements.
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:What do the two items (COIL:873347 HEAT: number) on the label of the raw material of aluminum coil stand for?
COIL means aluminum coil and HEAT means heating, so together they mean hot rolled coil.
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:Why there is arc panel after aluminum coil straightening?
The aluminum coil can only become flat and straight after being planished on stretch bender.
Q:What is color aluminum coil?
Colored aluminum coil is that the aluminum alloy whose surface has been shaded. The surface color after special treatment will not fade within 30 years at least because of the stable performance and good corrosion resistance. The weight per unit volume of color aluminum coil is the lightest among metal materials because of the low density and high hardness. Color aluminum is a newly emerging material in the field of doors and windows. Compared with steel, the biggest advantage is unparalleled firmness, varied colors and non-toxic for which steel has always been blamed. Therefore, it is widely used in areas such as doors and windows, sunroom and balcony seal. Color coated aluminum coil has become one of the most popular decorative material which is environmentally-friendly, durable and aesthetic. As a decorative material, it has the following unparalleled advantages: uniform color, bright and clean, strong adhesion, durability, anti-acid and anti-alkali, corrosion resistance, wind and weather resistance, decay and abrasion resistance and ultraviolet proof. Products categories: polyester coated aluminum coil (PE) and perfluorocarbon coated aluminum coil (PVDF).
