Characteristics and Application of Titanium
Abstract: Titanium metal has the characteristics of very high strength, excellent corrosion resistance, difficult to cold work, good weldability, about 40% lighter than steel, 60% heavier than aluminum, low conductivity, low thermal expansion rate, high melting point, etc. High purity titanium can be made into all kinds of pure titanium products. Such as titanium powder, titanium rod, titanium plate, titanium tube and so on. The details are as follows:
Characteristics and Application of Chromium Metal
Abstract: Chromium is often used as a chromium coating. Chromium plating process is generally divided into three types: decorative coating, hard chromium coating and black chromium coating. The decorative chromium coating is usually plated on the outside of the nickel layer as the top layer, and the coating has a delicate polishing effect like a mirror. As a decorative post-treatment process, the thickness of chromium coating is only 0.006 mm. The sputtering targets commonly used for chromium coating are as follows:
Characteristics and Application of Aluminum
Abstract: The application history of aluminum is relatively short, but the output of aluminum products on the market has far exceeded the total of other non-ferrous products. In the high-tech field, the application of aluminum products is everywhere. For example, spherical aluminum powder in aluminum powder can be applied to 3D printing. High purity aluminum can also be used as evaporation material of aluminum block, aluminum sputtering target, aluminum alloy sputtering target etc.
Characteristics, Application and Introduction of Cast Iron
Abstract: Cast iron is the name for a mixture of many elements, including carbon, silicon and iron (hence, iron powder is often used). The higher the carbon content is, the better the flow characteristics will be. Here, carbon is in the form of graphite and iron carbide (carbon can also be used to make graphite crucibles).
Incremental Method VS Decrement Method in Sample Weighing
Abstract: Sample weighing is an important part of the analysis experiment. The inaccurate weighing will lead to the failure of the whole experiment. Therefore, we should choose the right weighing method when weighing. Such as increment method and decrement method. When it comes to increment method and decrement method, what's the difference between them? How to choose?
Analysis of the Reasons for the Inaccurate Weighing of Samples in the Experiment
Abstract: Sample weighing is an important part of the analysis experiment. The inaccurate weighing will lead to the failure of the whole experiment. If we always say that we are not on time, we need to analyze the reasons in detail. Generally speaking, the reasons for the inaccurate weighing of samples can be divided into four aspects: the scale is not calibrated, the environment and the physical factors of the sample influence and improper operation etc.
