South Africa Aluminum Window Frame Profiles Frame Casement
Connector Brown Aluminium Extrusion
Features of Aluminum Extrusion:
The density of aluminum profile is only 2.7g/cm3, about 1 / 3 of
that of steel, copper or brass (7.83g/cm3 and 8.93g/cm3
respectively). Aluminum shows excellent corrosion resistance under
most environmental conditions, including air, water (or brine),
petrochemical and many chemical systems.
Aluminum profile is often selected because of its excellent
conductivity. On the basis of equal weight, the conductivity of
aluminum is nearly 1 / 2 of that of copper.
The thermal conductivity of aluminum alloy is about 50-60% of that
of copper, which is beneficial to the manufacture of heat
exchangers, evaporators, heating appliances, cooking utensils, as
well as automobile cylinder heads and radiators.
Aluminum profile is non ferromagnetic, which is an important
characteristic for electrical industry and electronic industry.
Aluminum profiles cannot spontaneously ignite, which is important
for applications involving handling or contacting flammable and
The machinability of aluminum profile is excellent. In various
deformed aluminum alloys and cast aluminum alloys, as well as in
various states after the production of these alloys, the machining
characteristics change greatly, which requires special machine
tools or technologies.
The variation of allowable deformation is dominated by specific
tensile strength, yield strength, ductility and corresponding work
Aluminum has high recyclability, and the characteristics of
recycled aluminum are almost the same as that of primary aluminum.
Broken Bridge Aluminum Windows Doors Profiles:
Broken bridge aluminum doors and windows are mainly made of
heat-insulating broken bridge aluminum profiles and insulating
glass, which have the functions of energy saving, sound insulation,
noise prevention, dust prevention, waterproof and so on.
1. Good thermal insulation;
2. There is a drainage outlet designed to ensure smooth drainage
and good water tightness;
3. The three-way sealing structure separates the water vapor
chamber, realizes the balance of water pressure and air pressure,
and prevents condensation and frost;
4. Metal material, heat insulation strip, high temperature
resistance, non combustion, fire prevention function;
5. Broken bridge aluminum doors and windows do not produce harmful
materials in the production process, and the materials can be
recycled, which belongs to green building materials;
6. High strength, not easy to deformation and corrosion, almost no
1. To achieve the thermal insulation performance of broken bridge
aluminum doors and windows, PA66 thermal insulation strip is
required, but its price is high, so the price of broken bridge
aluminum doors and windows is also high.
2. In addition, because PVC spacer is cheaper, some illegal
businesses may cut corners, so they need to pay more attention when

Anode effect is a special phenomenon in molten salt electrolysis,
especially in electrolytic aluminum production. In production, when
the anode effect occurs, the voltage of the electrolytic cell rises
sharply, reaching 20 ~ 50V, sometimes even higher. Its occurrence
has a great impact on the whole electrolysis series, reduces the
current efficiency, affects various technical indexes of
electrolysis, reduces the output and quality of aluminum, and
destroys the stable power supply of the whole electrolysis series.
In terms of treatment methods, there are no more than two kinds:
extinguish with effect rod (wood rod), or reduce the anode and
increase the blanking amount of alumina, so as to extinguish the
anode effect. No better treatment has been found.
The anode effect occurs because the oxygen-containing ions in the
electrolyte gradually decrease with the progress of the
electrolysis process. When it reaches a certain degree, fluorine
precipitates and reacts with the anode carbon to form carbon
fluoride. When the carbon fluoride decomposes, fine carbon
particles are precipitated. These carbon particles are attached to
the anode surface to prevent the contact between the electrolyte
and the anode, The electrolyte can't wet the anode well, just as
water can't wet the oiled surface, so a layer of gas film with poor
conductivity is formed between the electrolyte and anode, and the
anode overvoltage increases, causing the anode effect. When new
alumina is added, oxygen is precipitated on the anode, which reacts
with carbon powder to gradually calm the anode surface, reduce the
resistance, and the electrolysis process tends to be normal.
