The Basic Method of Selection of Aluminum

The international community has registered more than 1,000 kinds of alloy grades, each grade there are a variety of body shape, hardness, strength, corrosion degree, machining, welding, decorative, etc. There are obvious differences. When selecting grade aluminum and state, is difficult to satisfy the above aspects, it is not necessary, should be based on performance requirements, the use of environmental factors, processes, etc., to set priorities for various properties before they make a reasonable selection, to ensure performance under the premise of reasonable control costs.

 

Corrosion resistance:

 

Corrosion resistance, including resistance to chemical corrosion, electrochemical corrosion, stress corrosion and other properties. In general: 1 Series best corrosion resistance of aluminum, 5 and performed well, followed by the 3 Series and 6 Series, 7 Series 2 system and poor. Corrosion resistance of the principle of selection should be based on the use of the occasion. High-strength alloys in corrosive environments, you must use a variety of corrosion resistant composite materials.(aluminum checker plate price)

 

Processing performance:

 

Processing features include line performance in cutting and the like. (aluminum floor plate sale)Because formability with the state, the choice of alloy grades, need to consider the strength of the scope of the various states, usually forming high-strength material is not easy. If you want to be on the aluminum bending, stretching, deep drawing and other forming process, forming fully annealed condition best. On the other hand, the heat treatment state of the material forming the worst. Cutting aluminum alloy composition and have a great relationship, usually high strength aluminum alloy cutting of better contrast, low intensity were poor machinability. For molds, machinery parts and other products require cutting, cutting of aluminum is an important consideration.

 

hardness:

 

Many customers buy very concerned about the hardness of aluminum, aluminum alloys with the chemical composition of the first hardness has a direct relationship. In fact, the various states have a greater impact. From the highest possible hardness of view: 7 Series, 2 Series, 6 Series, 5 Series, 3 Series, (tread plate aluminium)1 Series descending order.

 

strength:

 

Strength must be taken into account when designing the product an important factor, especially when an aluminum alloy as a structural member, should be based on the pressure, select the appropriate alloy. Minimum strength aluminum, and 2 and 7 Series heat-type alloy highest intensity. Hardness and strength have some positive correlation.

 

Welding performance:

 

Aluminum welding majority had no problems, especially some 5 series aluminum alloy, it is designed for welding into account and design.(3003 h14 aluminum) In contrast, Part 2 and 7 Series aluminum welding more difficult.
