General Comparison between Cast Iron and Steel

Cast iron and steel may look very similar on the surface, and they have different advantages and disadvantages from production to application. Understanding these advantages and disadvantages, and choosing the right ones may mean unforgivable differences between strength and durability and cracked or deformed parts, which can quickly lose luster. Carbon content Both iron and steel are ferrous metals mainly composed of iron atoms. In manufacturing, however, it’s not that simple. There are many different alloys and grades. In fact, carbon composition is the main difference between cast iron and steel. Cast iron usually contains more than 2.5% carbon, while … Read more

Application of Grain Growth Inhibitors in Cemented Carbide

When WC grains in cemented carbide are less than 0.5 μ m, the finer the grains are, the fewer the defects are, and the higher the bending strength and hardness are The particle size of WC powder used to produce ultrafine cemented carbide is much smaller than that of WC powder used in general cemented carbide. The WC powder has high activity and is easy to cause grain growth in the sintering process, which is one of the crack sources. At present, there are two main methods to control the grain size: First, a new sintering process is adopted. The … Read more

Something Informative about Metallurgy

Powder metallurgy is the technology of making metal powder or using metal powder (or mixture of metal powder and non-metal powder) as raw material, through forming, sintering, and manufacturing metal materials and various types of products. There are some similarities between powder metallurgy and ceramic production, which belong to powder sintering technology. Therefore, The metallurgy technology can also be used in the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solve the problem of new materials and plays an important role in the development of new materials. Application fields of powder metallurgy First of … Read more

What You Should Know about 3D Printing

With pricing of 3D printers comes down in modern time, it’s safe to say everybody have gotten the access to exert the machine for their own purpose. Before purchasing your own 3D printer, you are probably interested in 3D printer’s history and development. What is 3D printing? Comparing to material removal forming method such as drilling, it’s a process to adding material, which is called additive manufacturing, rapid prototyping, and solid free form fabrication, rather than removing excess material from workpiece. It was introduced for commercially use in the late 1900s by Charles Hull. Which is followed by many 3D industrial … Read more
