Main Tip: What are the surface treatment processing methods for aluminum alloy and how is the cost of aluminum fabrication calculated?
Due to its easy processing and excellent physical and chemical properties, aluminum and aluminum alloys have become the second-largest metal materials currently used. The widespread application of aluminum and aluminum alloys is mainly due to its easy processing and excellent physical and chemical properties, which become the second-largest metal materials currently used behind steel materials. (Aluminum fabrication factories, blasting oxidation factories, aluminum alloy fabrication factories, surface treatment factories, aluminum alloy unit price, aluminum housing unit price, etc.)
The widespread application of aluminum and aluminum alloys is mainly based on its three major properties:
1, Light weight (its density is about 2.7);
2. High mechanical strength can be obtained after proper alloying and heat treatment;
3. And pure aluminum has good corrosion resistance.
4. Aluminum fabrication and other properties of aluminum alloys are: Excellent thermal conductivity, conductivity and reflectivity; its strong ductility and low processing costs; due to its non-magnetic, high value of waste recovery and its corrosion products are non-toxic and colorless, which make it widely applicable to the chemical and food industries.
At the same time, aluminum can get other superior performance after different treatments. In general, the choice of processed materials for aluminum fabrication depends on its mechanical properties, physical and chemical properties, and its price. Due to the high price of other light metals, aluminum fabrication must be considered economically when it is selected. For example, strength requirements should be considered together with lighter weight and better corrosion resistance. In addition to meeting the mechanical properties, the choice of a special alloy still requires consideration of the process and conditions of use. In so many metal materials, aluminum and aluminum alloys meet the requirements of most industries for metal performance. However, aluminum alloy materials are low hardness and poor wear resistance, and abrasion damage often occurs. Therefore, before the aluminum alloy is used, it is often required to go through a corresponding electroplating process to meet its adaptability and safety to the environment. Industrial aluminum and aluminum alloys all require protective measures to improve their corrosion resistance. There are many methods of aluminum surface treatment, such as anodization, chemical conversion film, electroless nickel plating, organic coating, corrosion inhibitor treatment, etc., but the method of aluminum surface treatment needs to be selected according to the following conditions:
● The processing and use environment of aluminum products, refer to the environment exposed to indoor, outdoor, marine atmosphere and easy to generate internal stress.
● The base materials, means the suitability of certain selected alloys for surface finishing.
● For decorative purposes, such as dyeing anodizing, paint coloring, and reflectivity.
● Special purposes, such as additional requirements for hardness, wear resistance, insulation, etc.
● Whether processing costs and process complexity are tedious.
