Aluminum Windows Doors:
Thickness There are 70 series and 90 series of aluminum alloy sliding doors,
and 70 series can be used for aluminum alloy sliding doors in
residential buildings. Series number refers to the millimeter
number of the structural dimension of the door frame thickness.
There are four kinds of aluminum alloy sliding windows: 55 series,
60 series, 70 series and 90 series. Series selection should be
based on the size of the window opening and the local wind pressure
value. Aluminum alloy sliding window used as closed balcony shall
not be less than 70 series.
Strength The tensile strength should be 157 n / mm 2 and the yield strength
108 n / mm 2. When purchasing, the profile can be bent moderately
by hand, and it should be restored to its original state after
releasing.
Chroma The color of the same aluminum alloy profile should be consistent.
If the color difference is obvious, it is not suitable to purchase.
Planeness Check the surface of aluminum alloy profile, there should be no
depression or bulge.
Gloss Aluminum alloy doors and windows to avoid the purchase of open
surface bubbles (white spots) and ash (black spots), as well as
cracks, burrs, peeling and other obvious defects of the profile.
Oxidation Degree The thickness of oxide film should be 10 microns. When purchasing,
you can draw on the profile surface to see whether the oxide film
on the surface can be wiped off.
Specifications 1 the opening size of doors and windows shall comply with the
provisions of GB / T 5824 "series of opening size of doors and
windows in buildings". 2 dimensions and specifications of common window openings one thousand and two hundred × 1500mm one thousand and five hundred × 1500mm one thousand and eight hundred × 1500mm
Aluminum Profiles Features:
Corrosion Resistance The density of aluminum profile is only 2.7g/cm3, which is about
1/3 of that of steel, copper or brass (7.83g/ cm3, 8.93g/ cm3,
respectively). In most environmental conditions, including in air,
water (or salt water), petrochemistry and many chemical systems,
aluminum can show excellent corrosion resistance.
Conductivity Aluminum profile is often selected for its excellent conductivity.
On the basis of equal weight, the conductivity of aluminum is
nearly 1/2 of copper.
Thermal Conductivity The thermal conductivity of aluminum alloy is about 50-60% of
copper, which is beneficial to the manufacture of heat exchanger,
evaporator, heating appliance, cooking utensil, cylinder head and
radiator of automobile.
Nonferromagnetism Aluminum profile is non ferromagnetic, which is an important
feature for the electrical and electronic industries. Aluminum
profiles cannot be self ignition, which is important for the
application of handling or contacting inflammable and explosive
materials.
Processability The processability of aluminum profile is excellent. In various
deformation and casting aluminum alloys, and in the various states
after the production of these alloys, the machining characteristics
have changed greatly, which requires special machine tools or
technologies.
Formability The allowable deformation is controlled by specific tensile
strength, yield strength, ductility and corresponding processing
hardening rate.
Recyclability Aluminum has high recovery, and the characteristics of recycled
aluminum are almost the same as that of primary aluminum.
