Main Characteristics and Applications of Aluminum Alloys for Casting
ZL101 (ASTM A356) - Aluminum-magnesium-silicon ternary alloy. Characteristics: Excellent casting properties, high fluidity, no tendency to hot cracking, low linear shrinkage, high airtightness, but a slight tendency to develop concentrated shrinkage and porosity; fairly ...Read more -
Characteristics and Application of Gray Iron Castings and Ductile Iron Castings
Characteristics and application of gray iron castings HT100 (EN-GJL-100) Characteristics: It is a low-strength cast iron part with good casting performance, simple process, low stress, no artificial aging treatment, and excellent vibration reduction. Application: It is s...Read more -
Growth of Cast Iron
When cast iron components operate at high temperatures, they may undergo an irreversible dimensional expansion known as growth. This phenomenon not only reduces the strength of the cast iron but can also damage other components in contact with it. Cast iron growth is mos...Read more -
Internal Defect Inspection of Castings – Radiographic Testing
Internal defects of castings refer to various defects that exist inside castings and destroy the density or uniformity of castings, such as internal shrinkage, shrinkage, pinholes, pores, inclusions, internal cracks, segregation, etc. For these defects that are not expos...Read more -
Common Methods for Testing and Sampling Mechanical Properties of Castings
The mechanical properties of castings are important indicators of the quality of most castings and are often used as the basis for acceptance. However, it is very difficult and usually impossible to apply the same load to the castings as the working conditions to measure...Read more -
Gray Cast Iron Performance – Service Properties
Machines operating under different conditions require gray cast iron components to have service properties that cannot simply be characterized by conventional mechanical properties. Designers and manufacturers must give this due attention. Wear Resistance Gray cas...Read more -
Gray Cast Iron Performance – Mechanical Properties
The mechanical property data of gray cast iron is generally obtained from separately cast ⌀30mm test bars. Since the microstructure and mechanical properties of gray cast iron are significantly affected by the cooling rate during the solidification and eutectoid transfor...Read more -
Characteristics of Clay Sand Molds for Iron and Steel Castings
According to the different types of casting alloys, it can be divided into casting sand for cast steel, cast iron, cast copper, aluminum alloy castings, and magnesium alloy castings. Different casting alloys have different pouring temperatures and casting properties, and...Read more
