Aluminum presents manufacturers and end-users with several benefits over other materials, including Strong, but lightweight construction. Aluminum demonstrates an excellent strength-to-weight ratio. Aluminum and aluminum alloys can exhibit strength equal to steel with one-third of the weight.
Durability. Aluminum material exhibits resistance to various environmental factors, including corrosive substances and UV radiation. This quality ensures a longer service life of aluminum products.
Flexibility and ease of fabrication. As aluminum is available in a variety of alloys with varying properties, it can be worked by several different manufacturing processes—including rolling, extrusion, forging, casting, etc.—for virtually any application.
Non-combustible. While aluminum does melt at around 600 degrees Fahrenheit, it does not burn or release potentially harmful gases.
Thermally and electrically conductive. Aluminum offers high electrical and thermal conductivity properties, enabling it to be used in electrical and thermal transfer applications.
Stainless Steel The Basic Types Of Surface Processing.
There are roughly five types of surfaces that can be used for stainless steel. They can be combined to produce more end products.
The five species are:
1. rolling surface processing
2. mechanical surface processing
3. chemical surface processing
4. mesh surface processing and color surface processing
There are also some special surface treatments, but no matter which one is specified, the
Following steps should be followed:
1. Work with the manufacturer to agree on the required surface processing, it is better to prepare a sample as the future batch production standards.
2. When used in large areas, such as composite boards, it is necessary to ensure that the same batch of base coil or coil is used.
3. Selection of surface processing should take into account the manufacturing process, such as: in order to remove beads, may be necessary to grind the weld, but also to restore the original surface processing. It is difficult or even unable to meet this requirement.
4, for some surface processing, grinding or polishing texture is directional, is called unidirectional. If this pattern is made vertical rather than horizontal when used, dirt will not easily adhere to it and will be easy to clean.
How to remove rust from galvanized steel pipe?First, the outside of the steel is coated with a solvent to remove external impurities, and then a wire brush is used to remove rust, loose or inclined rust, welding slag, etc., and rust can also be removed by pickling.
What are the commonly used processing techniques for stainless steel plates?Stainless steel plates go through various processes to obtain certain quality and performance, thus obtaining different properties. The following are the different processes that are often carried out on steel plates:
Heat treatment - temperature control operation to improve the physical and even structural properties of metal.
The five main heat treatment processes for stainless steel plates are quenching, surface hardening, annealing, tempering and normalizing.
Normalizing this special heat treatment heats the metal to a critical temperature and then immediately cools it in still air.
This will refine the structure of the internal crystal and gradually eliminate the internal stress.
Rolling - the metal material is pushed by a pair of rollers, and the size of the process depends entirely on the temperature range used.
If the temperature of the material exceeds the recrystallization temperature, the rolling process is called hot rolling.
On the other hand, cold rolling belongs to the process of using metal materials lower than the typical recrystallization temperature.
These processes are not necessary for the processing of stainless steel plates. They are only processing to achieve certain characteristics. The factory needs to apply specific processing processes to various specific grades of stainless steel in order to obtain good use.
