Metallographic Analysis

👏 High-temperature titanium alloy is a type of titanium alloy that can be safely and reliably used in service environments above 400℃. Due to its ability to maintain high tensile strength at high temperatures, along with excellent thermal stability, good fatigue performance, and good creep resistance, it is mainly used to manufacture discs, blades, intake […]

Aluminum alloy is highly favored due to its light weight and corrosion resistance. The application of hard anodizing technology further enhances the hardness and wear resistance of aluminum alloy, and it is widely used in high-end fields such as aerospace and automotive manufacturing. However, to accurately assess the quality and performance of the hard anodizing […]

Magnesium alloys, as the lightest structural metal materials, are widely used in various fields due to their low density, high specific strength, good thermal conductivity, and electromagnetic shielding properties. They are applied in aerospace (such as satellite brackets, aircraft landing gear components), automotive industry (engine blocks, transmission housings), electronic equipment (laptop computer shells, mobile phone […]

Monocrystalline silicon billet refers to the silicon crystal raw material with a specific shape and size formed by arranging silicon atoms in a regular diamond lattice through a specific process. It has a metallic luster, is mostly dark gray in color, and is hard and brittle in texture. It has a relatively high hardness but […]

In our world of life – screws, this seemingly insignificant little object, is like a silent and diligent behind-the-scenes hero, playing an irreplaceable role in every corner. In terms of appearance, it is simple and unique. On the slender screw, the spiral threads are dense and neatly intertwined, like steps winding upwards. In terms of […]

High-entropy alloys (HEAs) are reshaping the future of materials science. With exceptional strength, high-temperature resistance, and outstanding corrosion performance, HEAs are making waves in aerospace (engine blades), nuclear energy (reactor materials), defense (missile casings), biomedical (orthopedic implants), and renewable energy sectors. Structurally complex and chemically diverse—typically composed of five or more principal elements—HEAs often present […]

🔎 Amid the flames of spacecraft re-entering the atmosphere and in the circuit heart of new energy vehicles, the “tough guy and wise man” duo of carbon-carbon composite materials and copper welded joints are writing a material legend. As metallographic engineers, how do we decipher its microscopic codes? Next, we will take you on a […]

It is often mistaken for gold by people and is thus called “fool’s gold”. Pyrite is the most widely distributed sulfide in the earth’s crust and forms under various geological processes. It can be found in many rocks and ores (including coal seams) and has ornamental value. Industrially, it is used for extracting sulfur and […]

Do you know? There is a kind of metal material that is quietly changing the world. It has excellent properties such as high strength, low density, corrosion resistance and high temperature resistance. It is titanium alloy. It has an extremely light “weight”, yet possesses extraordinary “power”. In the aerospace field, it helps aircraft soar lightly […]

🔎 AZ31 magnesium alloy is a typical deformed magnesium alloy. With magnesium as the matrix, it provides the alloy with the basic characteristic of low density, which gives AZ31 magnesium alloy a significant advantage in lightweight applications. With its high ductility, high thermal conductivity and good electromagnetic shielding property, it is widely used in structural […]

🎉 Gold alloy sheets generally refer to thin sheet materials made of gold alloy used for connecting, fixing or packaging electronic components, etc. Due to the extremely high electrical conductivity, good thermal conductivity, high chemical stability, good flexibility and ductility of gold, the surface of the gold alloy sheets is widely used in microelectronic packaging […]

It was not only a survival tool in the Stone Age, a symbol of ritual in the Bronze Age, but also an aesthetic of assassination in the Iron Age. From Jing Ke’s revealing the dagger at the end of the map in ancient times to Li Bai’s heroic spirit expressed in his poems, from the […]

Aluminum nitride ceramic is a material with excellent comprehensive properties. It has a hexagonal wurtzite structure and is mostly gray or off – white. Besides features such as high thermal conductivity, high insulation, and a thermal expansion coefficient matching that of silicon, it also has high strength, high hardness, and good chemical stability. It is […]

The main method adopted is hot galvanizing. The galThe main method adopted is hot galvanizing. The galvanized layer has excellent resistance to atmospheric corrosion and can easily form a protective film on the surface at room temperature. Therefore, the largest application of zinc is in the galvanizing industry, which is widely used in automobiles, construction, […]
