What is Cast Iron?

For most guys working in the industry of metal machining, Cast iron must be a kind of familiar material. What is cast iron? First of all, it’s a sort of ferro-carbon alloy that contains more than 2.11% of carbon and small amounts of Si, Mn, S, and P. The mechanical properties of cast iron are lower than that of cast steel. But it has excellent castability, shock absorption, wear resistance and cutting machinability. The production process is simple and the cost is low. It is one of the most commonly used metal materials in engineering. Table of Contents Classification of … Read more

8 Common Microstructures of Metal and Alloy

Modern materials can be divided into four categories: metals, polymers, ceramics and composite materials. Despite the rapid development of macromolecule materials, steel is still the most widely used and most important material in the current engineering technology. What factors determine the dominant position of steel materials? Now let’s introduce it in detail. Iron and steel are extracted from iron ore, rich in sources and low in price. Iron and steel, also known as iron-carbon alloy, is an alloy composed of iron (Fe) and carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) and other small elements (Cr, V, etc.). … Read more

14 Common Types Of Porous Materials

UPAC separates pores into micropores (<2 nm), mesopores or mesopores (2 to 50 nm), macropores (> 50 nm) according to the pore size scale; according to the latest definition, the pores are subdivided into Micropores (<0.7 nm) and micropoles (0.7-2 nm), while wells below 100 nm are collectively referred to as nanopores. So how are the names of these hole materials come from?

History And Development Of Tungsten Carbide Rolls

Continuously plastically deformed main working parts and tools on the rolling mill. The roller consists of a roller body, a roll neck and a shaft head. The roll body is the middle part of the roll that actually participates in rolling the metal. It has a smooth cylindrical or grooved surface. The roll neck is mounted in the bearing and the rolling force is transmitted to the frame via the bearing housing and the pressing device. The shaft end of the transmission end is connected with the gear seat through the connecting shaft, and transmits the rotational torque of the … Read more

Heat Treatment of Tungsten Carbide Products

Cemented carbide(hardmetal) is a general term for alloys composed of carbides, nitrides, borides, or silicides of high melting point metals (W, Mo, Ti, V, Ta, etc.). Divided into two major categories of casting and sintering. The cast alloy has high brittleness and low toughness, and has little practical application value. Widely used are sintered alloys, which are generally sintered from tungsten carbide or titanium carbide and cobalt powder and have high hardness, wear resistance and hot hardness. Mainly used to manufacture high-speed cutting and processing of hard materials, in recent years, the use of carbide in the mold industry is … Read more

Features And Preparation Of Tungsten Carbide Mining Tool

Cemented carbide is a composite material composed of high-hardness refractory metal carbides and cemented metals. Because of its high hardness, wear resistance, and stable chemical properties, it is used in modern tool materials and wear-resistant materials. High temperature and corrosion resistant materials occupy an important position. At present, tungsten carbide-based hard alloys are the most widely used among the carbides produced in the world, with the largest output and the most extensive use. Among them, the WC hard alloy used in mines has been regarded as the “tooth” of the mine development, oil drilling and geological exploration industries, and has … Read more
