Shenyang Greiner Company will help you solve common problems in the aluminum processing process:
. One of the biggest headaches we have in the mold manufacturing process is that after completing most of the processing steps, suddenly It was found that there were sand holes or unknown particles on the final polished surface, and now the workpiece was scrapped.
Answer: The unique grain refinement process ensures that all aerospace product series have passed the ultrasonic flaw detection process inspection of aerospace aluminum alloy products and are free of sand holes, horizontal lines, bubbles and impurities. The heat treatment technology is excellent, and the product can maintain consistent strength and hardness below the thickness (or diameter). All production processes are computer controlled, with minimal human deviation, and the performance can be guaranteed to be the same in different batches of production.
.Our products are electronic manipulators and electronic tooling boards. This aluminum part requires no slight deformation after processing. Why did the European boards or domestic boards we previously bought on the market change within one or two days after processing? Sudden transformation?
Answer: The perfect pre-stretching process to eliminate internal stress completely eliminates internal stress, and the product will not warp, crack or deform during processing and stress.
.Our products are used for mechanical structural parts. Are the aluminum parts required to have stable and consistent strength and not break or deform at a certain point?
Answer: The unique grain refinement process ensures that all aerospace product series have passed the ultrasonic flaw detection process inspection of aerospace aluminum alloy products and are free of sand holes, horizontal lines, bubbles and impurities. The heat treatment technology is excellent, and the product can maintain consistent strength and hardness below the thickness (or diameter). The production process is all computer controlled, with minimal human deviation. Different batches of production can also ensure the same perfect performance. The pre-stretching process to eliminate internal stress completely eliminates internal stress, and the product will not warp or crack during processing and stress. and deformation.
.When we process precision workpieces, we require very precise thickness and tolerances. If the tolerances are uneven, self-correction will not only increase costs, waste time, but sometimes also cause the workpieces to be scrapped?
Answer: All products comply with the American Society for Testing and Materials specifications and the Aerospace Materials Specifications. The tolerance index of most products can exceed the standard tolerance accuracy, and the tolerance index of some products can even exceed the standard tolerance accuracy.
.We are a hardware processing factory. In the past, we often encountered "knife sticking" and "crash" when processing aluminum parts, resulting in low surface finish and dimensional accuracy of the workpiece, and a high scrap rate.
Answer: All products comply with American Society for Testing and Materials specifications and aerospace material specifications. The tolerance index of most products can exceed /tolerance accuracy, and the tolerance index of some products can even exceed /standard tolerance accuracy. The chemical composition, strength and The deviation in hardness is minimized, and the phenomena of "sticking" and "collapse" will not occur during processing. The heat treatment technology is excellent, and the strength and hardness of the product can remain consistent below the thickness (or diameter).
.Our products are all made of aluminum alloy. During the production process, we found the thorny problem is that the quality of the aluminum alloy purchased before was unstable. It was OK during the trial but changed during use. Sometimes the same batch of aluminum materials The quality also varies greatly, making it difficult to adapt the production process. Product quality is also difficult to guarantee.
Answer: The production process is all computer controlled, with very little human deviation, and the performance can be guaranteed to be the same in different batches of production.
.Our aluminum workpieces need to work continuously or intermittently in a high temperature environment of ℃. Can Alcoa meet the requirements?
Answer: The heat treatment technology is excellent. The strength and hardness of the product can be consistent below the thickness (or diameter) and will not cause permanent deformation in the working environment of ℃.
.Our products have a bending process during the manufacturing process, and it is required that there are no cracks or fine lines in the bends of the aluminum parts.
Answer: All the plates have passed the semiconductor bending test, and the bending will not cause cracking.
.The aluminum plate we need is a plate used in precision machinery, and the coloring effect is required to be beautiful. Can Alcoa meet this requirement?
Answer: The coloring effect of aluminum plates is determined by three factors: lattice structure arrangement, tissue density and heat treatment technology. Alcoa's product production technology is exquisite, chemical composition control is precise, and inspection procedures are complete, ensuring Alcoa's consistent excellent quality.
. Often seen in engineering materials or drawings, what does it stand for?
Answer: It is the abbreviation of the full English name C, which is the abbreviation of the American Aluminum Association. It is only crowned in front of the deformed aluminum alloy grade. It means that this grade is produced and inspected according to Alcoa standards.
.Superduralumin must be harder than duralumin, right?
Answer: Not entirely true. Certain technical performance indicators of aluminum alloys (such as strength, hardness, etc.) can only be compared when they belong to the same standard, the same grade and the same processing state. Such as the hardness of Alcoa (B), but the hardness of the state (B) is much lower than the hardness of Alcoa. It is often seen in the market that some brands have misalignment (such as the hardness of domestic brands of duralumin is lower than), which is this reason.
.Whether it is domestic aluminum alloy or European aluminum alloy, as long as the grade can correspond to Alcoa, the quality will be roughly the same, right?
Answer: In addition to being closely related to production technology, industrial equipment level, labor quality and other factors, the quality of aluminum alloy products is also related to the following factors:
Products under different production standards and specifications Quality varies as its requirements vary.
If the buyer does not require certain process treatment and inspection items of aluminum alloy products, the supplier will not provide them, which may cause significant differences in product performance. For example, the heat-treatable strengthened alloy series in Alcoa's products have been treated with internal stress relief processes, and have passed ultrasonic flaw detection, spectral analysis, semiconductor bending tests, micro-corrosion tests, electromagnetic (eddy current) tests, and cracking susceptibility tests. Ensure Alcoa products excel in every aspect of the marketplace.
The numbers in the grades of wrought aluminum or aluminum alloys only represent their purity or the maximum average percentage content of certain alloy chemical elements.
Even the chemical composition content of products of the same brand varies due to different production standards and different production batches.
.Why can’t aluminum alloy anodized parts be used in a sexual environment?
Answer: The component of the oxide film formed by the anodizing of aluminum alloy is aluminum oxide. The film layer is dense and wear-resistant. Aluminum oxide is an amphoteric substance and will react with it to dissolve the film.
.Why are the colors of different types of aluminum materials inconsistent after anodization?
Answer: Different types of aluminum materials have different alloy compositions and contents. The purity of aluminum directly affects the transparency of the oxide film. The elements in the alloy, , , will affect the color development of the oxide film, thus affecting the color of the film after oxidation.
. Are there obvious crystal spots after anodizing aluminum?
Answer: The occurrence of crystal spots is due to the segregation and aggregation of alloying elements in aluminum alloys due to improper extrusion process and irregular heat treatment, which leads to Intergranular corrosion, eventually precipitating white floc (), which dries to form crystal spots.
