Knowledge of Aluminum Profiles

Mar. 31, 2020

The most abundant metal in the earth's crust is aluminum, which accounts for 7.45% of the total mass of the earth's crust. Although aluminum has more reserves in the earth's crust than iron, the production process of aluminum is more complicated than iron. Since smelting requires electrolysis, the cost in the entire production process is higher than iron, so the price of aluminum is higher than iron.

Why is aluminum profile generally surface-treated?

If the aluminum profile is not surface-treated, it has an unattractive appearance and is easily corroded in the humid air. This makes it difficult to meet the requirements for high decorative and weather resistance of aluminum profiles in building materials. In order to improve the decorative effect and enhance the corrosion resistance And to extend the service life, aluminum profiles are generally surface treated. Xingfa Aluminium Factory has anodizing, powder coating, spraying fluorocarbon coating, electrophoretic coating, a broken bridge, and other technological means to meet customer's customized requirements.

Why choose aluminum instead of traditional steel?

Due to its excellent structural and functional characteristics, the surface of aluminum has a dense oxide protective film, has strong corrosion resistance, and can be repeatedly recycled and reused. With the improvement and improvement of aluminum and aluminum alloy material properties The scope of its application is constantly expanding, and materials such as "aluminum instead of wood" and "aluminum instead of steel" are becoming more and more widely used, and the characteristics of lightweight, energy-saving, ecology and recycling of aluminum profiles are further exerted.

Aluminum Profile

In general, aluminum profiles are used in the construction field for their unique decoration, excellent sound insulation, thermal insulation, and recyclability, which are in line with the concepts of green, environmental protection, and energy conservation advocated by the state. In the future, as the development of the aluminum profile industry and process technology becomes more mature, it will expand into more fields and develop in a diversified direction. It will be more widely used in construction, transportation, home appliances, aviation, machinery, and other industries.

As a typical non-ferrous metal, aluminum alloy has the advantages of lightweight and corrosion resistance, which makes aluminum profiles widely used in traditional industrial profiles, doors and windows, curtain walls, decorative materials, and other fields. In the production and processing of extruded aluminum profiles, detailed control is the key. A slight failure will affect product performance and quality, such as:

1) In order to facilitate the aging and circulating air supply, the extrusion aluminum profile must not be too dense when framing, and there must be a gap between the materials, especially for small materials and thick materials that are not ventilated. When the tube material is combined with the small material and the sheet material, the tube material is placed below.

2) Before the aluminum profile is loaded, the other special alloys and ordinary alloys should be separately installed for aging. The aging is to make the aluminum profile effective within a certain period of time. For production reasons, it is necessary to use the special alloy for aging. The process to age.

3) In terms of temperature setting and control, usually, there is a certain error between the temperature and the displayed temperature. When setting the table temperature, set it according to the actual temperature of the furnace, and pay close attention to the temperature fluctuations.

4) Aging of aluminum profiles: Aging must be carried out in strict accordance with the process requirements, and the holding time should be appropriate to prevent insufficient hardness due to under-aging or over-aging.
