6 Factors to Consider in Aluminium Profile Selection

Faced with a variety of industrial aluminum profiles, it is often difficult for users to choose. Today, we will introduce some factors to be considered when choosing industrial aluminum profiles. When choosing industrial aluminum profiles, the following points should be considered:

· Hardness

Hardness is, of course, the first issue for users to consider. Of course, they are also extremely concerned about whether the hardness of aluminum profiles can meet the applicable standards. I directly related the first choice of hardness to the chemical composition added, and there is a certain influence in terms of the highest hardness that can be achieved. The hardness of 7 series, 6 series, 4 series, 2 series, 5 series, 3 series, and 1 series materials decreases.

· Strength

Strength is an important factor to be considered in product production. When aluminum alloys are used as components, appropriate alloys need to be selected according to the pressure they can withstand. The strength of pure aluminum is the lowest, and the strength of the 2-series and 7-series heat-treated alloys is the highest, and the hardness and strength have a certain linear relationship.

· Corrosion resistance

Corrosion resistance includes chemical corrosion, stress corrosion resistance, and other properties. Generally, 1 series pure aluminum has the best corrosion resistance. The 5 series has good corrosion resistance, followed by the 3 and 6 series. The 2 and 7 series have relatively poor corrosion resistance. We should note the corrosion resistance. The principle of selection of properties depends on the occasion of their use. In the corrosive environment of high-strength alloys, various anti-corrosion composite materials must be used. In this way, the product can be effectively prevented from being corroded. Used more, the 5 series, and the 3 series are used more. It is unnecessary to choose the best 1 series pure aluminum material. It is also necessary to consider the cost. Generally, choose the appropriate one. Aluminum material will do.

· Machinability

Machinability includes formability and cutting performance. Considering that formability is related to the state. After selecting the corresponding aluminum alloy grade, it is also necessary to consider the strength range of various states. Generally speaking, aluminum with high strength is not easily formed, and the formability of the annealed material is the best after bending, stretching, deep drawing, and other forming processes of the aluminum material, while the formability of the heat-treated material is the worst. The machinability of aluminum alloy is poor, and the machinability is better for molds and mechanical parts.

· Weldability

The weldability of most aluminum alloys is good, and the representative ones are some aluminum alloys of the 5 series, which have excellent weldability. Relatively speaking, the weldability of the 2 series and 7 series is poor.

· Decorative properties

When users buy industrial aluminum profiles, their decorative properties are also very fancy. Generally, when aluminum materials are used in certain decorations or special occasions, they need to undergo anodized surface treatment and coating processing. and other processes and materials with better corrosion resistance have excellent anodizing performance, surface treatment performance, and coating performance.
