1. Compared with other commonly used metals, aluminum profiles have small density and light weight. The density is only 2.70 g / cm3, which is 1 / 3 of copper or iron. In the process of use, the required load-bearing capacity does not need to be considered.
2. Aluminum profiles are treated by hot and cold processes in the production process, which has strong corrosion resistance.
3. Aluminum profile has good ductility and can be made into light alloy with many metal elements. The material is high-quality.
4. Compared with other metal materials, aluminum has strong plasticity and good productivity, and has good advantages for production.
5. Aluminum profile has good casting performance and can be processed into aluminum profiles with different shapes.
6. The surface treatment performance is good and the appearance color is gorgeous.
7. It has stable chemical properties, no magnetism and can be recycled. It is a benign and recyclable metal material.
8. Small elastic coefficient and no spark due to collision and friction, which is the best performance in automobile technology.
9. It has good thermal conductivity and conductivity, and is outstanding in short-distance power transmission.
10. Compared with other metal materials, aluminum profiles have no metal pollution, toxicity and no volatile metal on the surface oxide layer.

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.
Q – What is the average lead time for pre production samples?
A – Our average lead time is normally 7 days for making new samples and 7 days for testing , totally need about 14days.
Q – What is the average lead time for mass production?
A – Our average lead time is delivery within 20-30 days after receive deposit and and moulds/samples are passed.
Q – What is CAD?
A – CAD stands for “computer assisted design” and it is a 3-D program that is used by our clients to provide our technicians with a three-dimensional example of the custom shape that they want made at GUANGDONG YONGLONG ALUMINUM.Aluminium Window Profiles
