Aluminum profile has many advantages in application, so it is very popular in the market. The aluminum profile titanium gold plating process belongs to the coating technology. It adds pre-plating and electroplating steps on the basis of the conventional titanium plating process. The aluminum profile process involves placing the activated plating parts in an aqueous solution of salt and hydrochloric acid for chemical treatment. So what are the advantages of aluminum profiles? How to distinguish the material of aluminum profile?
Insert picture description
The plating solution components of the electroplating process include nickel sulfate, nickel chloride, boric acid, sodium lauryl sulfate, saccharin, and brightener. This process has the advantages of simplicity, practicality and good effect. The film hardness of the titanium-gold-aluminum profile made by this process is HV≈1500, and it is 150 times more wear-resistant than 22K gold plating under the same conditions. It can be processed into various forms of gold, Various series of bright aluminum products in color and black.
What are the advantages of aluminum profiles?
The advantages of aluminum profile are as follows:
Aluminum profiles have lower density and lighter weight than other commonly used metals, with a density of only 2.70 g/cm3, which is 1/3 of copper or iron. There is no need to consider the load-bearing capacity during use.
In the production process, the aluminum profile adopts two processes of heat and cold treatment, which has strong corrosion resistance.
Aluminum profile has good ductility and can be made into light alloy with many metal elements with high quality material.
Compared with other metal materials, aluminum molds have strong plasticity and good productivity, and have good advantages for production.
Aluminum profiles have good casting properties and can be processed into aluminum profiles of different shapes.
Good surface treatment performance and bright appearance.
Stable chemical properties, non-magnetic, can be recycled and reused, is a benign and recyclable metal material.
The coefficient of elasticity is small, and there is no spark in collision and friction, which is the best performance in automobile technology.
It has good thermal conductivity and electrical conductivity, and has outstanding performance in short-distance power transmission.
Compared with other metal materials, aluminum profile has no metal pollution, no toxicity, and no volatile metal on the surface oxide layer.
How to distinguish the material of aluminum profile?
Look at the degree of oxidation: when purchasing, you can scratch the surface of the profile to see if the oxide film on the surface can be wiped off. Of course, this should not be done directly on the sample window, the owner can do it at the material vendor displayed by the business.
Look at the chromaticity: the same aluminum alloy profile should have the same color. If the color difference is obvious, it is not suitable for purchase. Generally, the section color of normal aluminum alloy profile is silvery white and the texture is uniform. If the color is dark, it can be concluded that it is recycled aluminum or scrap aluminum forging.
Look at the flatness: check the surface of the aluminum alloy profile, there should be no depression or bulging. The aluminum profile processed by the regular manufacturer has a smooth and bright surface. If it is a small workshop, due to the machine or raw materials, the surface of the profile will appear slightly bumpy. The balcony window synthesized by such aluminum profile is easily oxidized and deformed in the later stage.
Look at the strength: When purchasing, you can bend the profile moderately with your hands. If you bend the profile without any effort, then it can be determined that the strength of the aluminum profile is not up to standard, and the strength of the profile is not as hard as possible. Aluminum has a certain degree of toughness. For non-hard materials, this feature can be used to forge different shapes, so the owner must look for the brand and carefully observe when purchasing.
Look at the thickness: commonly used 70 and 90 series aluminum window profiles, the wall thickness should be 1.2-2.0 mm. The national standard for wall thickness of balcony window aluminum profile is 1.2mm.
6.Glossiness: Avoid buying profiles with obvious defects such as open bubbles and slag on the surface of aluminum alloy doors and windows, as well as cracks, burrs, and peeling. If there are the above phenomena, it can be concluded that secondary processing and forming of recycled aluminum or scrap aluminum. Such materials are prone to cracking and oxidation due to uneven texture and messy alloy ratio.
