Aluminum Extrusions

Factors to be considered in the design of extruded aluminum profiles

size
It is the primary consideration in designing aluminum profiles. The size needs to be determined according to your application needs, including length, thickness, width, etc. When determining the size of the aluminum profile, it is necessary to fully consider the load-bearing capacity and stress tolerance of the material to ensure that the profile can meet the required application requirements.

shape
It is also an important factor to consider when designing aluminum profiles. The shape of extruded aluminum profile includes cross-sectional shape and overall shape, which is the basis for realizing product structure and function. When designing aluminum profiles, the balance between product appearance requirements and performance requirements will be fully considered.

Aluminum Alloy Selection
It is also one of the factors that need to be fully considered when designing aluminum profiles. Aluminum profiles are usually made of some special aluminum alloy materials, which have excellent performance and special uses. Therefore, when choosing an aluminum alloy, it is necessary to fully understand its performance characteristics and make a reasonable choice according to actual needs.

tolerance
It is one of the factors that will inevitably appear in the production process of extruded aluminum profiles. Reasonably setting the tolerance can reduce the difficulty of the production process, ensure the accuracy and stability of the product size, and improve the overall quality of the product.

Extrusion Ratio, Tongue Ratio and Surface Finish
It is also a factor that needs to be considered when designing aluminum profiles. These factors have a great influence on the physical properties and surface quality of aluminum profiles. When formulating a design plan, these factors need to be fully considered to ensure the overall performance and quality of the product.

Finally, assembly issues also need to be considered. Aluminum profiles are often assembled with other parts in practical applications, so it is necessary to consider the degree of fit and connection with other parts to ensure the smoothness and correctness of the product assembly process.

In general, the design of extruded aluminum profiles requires comprehensive, systematic and scientific consideration of various factors to ensure that the quality and performance of the product meet the application requirements. Only in this way can we create better aluminum profile products and bring more convenience and benefits to people’s life and work.

The wall thickness of aluminum profiles that Xingda can provide

In extruded aluminum profiles, the wall thickness that Xingda can provide is divided into three categories, which are light, medium and heavy. These different wall thicknesses are selected based on your specific application needs.

The wall thickness of light extruded aluminum profiles is generally between 1.0mm and 2.0mm. This type of aluminum profile is very suitable for the fields of architectural doors and windows, furniture, aircraft models and electronic products.

The wall thickness of medium-sized extruded aluminum profiles is generally between 2.0mm and 3.0mm. This type of aluminum profile is widely used in larger building structures and mechanical equipment.

The wall thickness of heavy-duty extruded aluminum profiles is generally above 3.0 mm. This type of aluminum profile is commonly used in the manufacture of industrial and architectural structures for support or load bearing.

In short, extruded aluminum profiles have a variety of wall thicknesses for you to choose from. Selecting the appropriate wall thickness according to your specific application requirements can ensure that your products have better performance, strength and durability, and make them more durable Play a more important role in a wide range of application fields.

Alloy State Differences – Aging

Alloys are materials made by mixing two or more metal or nonmetal elements. It is precisely because alloys have more excellent physical and chemical properties than single-element materials, making them widely used in industrial production, construction, energy, aerospace, automobile manufacturing and other fields.

However, in the use of alloys, one needs to be aware of a state difference called aging. Aging refers to the phenomenon that the properties of an alloy will gradually change over time after receiving a specific heat treatment.

The strength and hardness of the alloy after aging heat treatment will gradually increase due to the continuous increase of precipitated phases. At the same time, aging will also have a certain impact on the ductility and toughness of the alloy. Since the crystallization state of the alloy and the number and size of precipitated phases change over time, when using the alloy, the aging state needs to be considered according to the specific application scenario and requirements.

However, the aging state is not a defect of the alloy. On the contrary, for different application environments and uses, the aging state can provide more excellent performance and more adequate utilization. For example, the axles of air vehicles and the blades of aircraft engines need to have characteristics such as high strength, high hardness and high temperature stability. These properties happen to be achieved through aging states.

In short, the aging state is one of the unique state characteristics of alloy materials. In a specific application environment, by choosing an appropriate aging state, alloy materials can produce excellent performance with better performance, so as to better serve our production and life. .

Performance-enhancing surface treatments for aluminum extrusions

In order to improve the performance of aluminum extrusion products, surface treatment is a very important step. Several surface treatment methods to optimize the surface of aluminum extrusion are introduced below.

1. Oxidation treatment

Oxidation treatment is a common surface treatment method, which can improve the corrosion resistance, wear resistance and decoration of aluminum by forming an oxide layer on the surface of aluminum extrusion. Oxidation treatment methods include sulfuric acid oxidation, sulfuric acid chromic acid oxidation and nitric acid oxidation.

Advantages of oxidation treatment：
