Tin Brass Adding tin to brass can significantly improve heat resistance of the alloy, which can especially improve resistance of the alloy to sea water. Therefore, tin brass can also be called admiralty brass. Tin can dissolve in the copper-based solid solution, playing a role of strengthening the solid...

Special brass The multiple alloys which are formed by adding other alloying elements to ordinary brass are called special brass. The common added alloying elements are lead, tin, aluminum, etc., and the multiple alloys can be called lead brass, tin brass and aluminum brass. The purpose of adding alloying...

Brass which is made of copper and zinc is called ordinary brass. A variety of alloys which is made of two or more elements is called special brass. For example, copper alloys are made of lead, tin, manganese, nickel, iron and silicon. Brass has strong wear resistance. Special brass has high strength,...

4. Designs of discharge systems  Overflow boxes and discharge passages with enough overflowing areas should be set up for molds, which is very important to ensure quality of die casts. People often overlook the problem of molten metal blocking the overflow passages too early. Reasonable structures...

4. The formulation and implementation of the die casting process The formulation and implementation of the die casting process are related to the quality of the die casting mold and equipment and the technical level of the operator. Lax implementation of die casting processes and their main parameters...

With development of science and technology, requirements of safety and beautiful appearance for die casting products gradually become higher and higher. The quality of the die casting part is evaluated differently based on the application. Today, JY is going to tell you how mold designs affect quality...

In order to cope with increasingly stringent fuel economy regulations, light weights of automobiles are general trends. The experimental results show that when weights of automobiles are reduced by 10%, fuel efficiency can be increased by 6% to 8%; curb weights are reduced by every...

Aluminum alloy die casting manufacturers must ensure the quality of their products in the production processes. In order to obtain the metal parts through die casting during the operation, we should pay more attention to the die casting processes. First, we need to smelt metal materials, and then inject...

With the continuous development of society, applications of aluminum alloy die casts also become very wide. Aluminum alloy die casts are often used for oil, industrial and mineral industries. In our daily life, this kind of die casting parts is mainly used in automotive field, thus so many people list...

1. The damage and failure of thermal fatigue cracking The molding surface and the inner part of the mold will deform under the influences of shock cooling and shock thermal in die casting process. Cyclic thermal stress results in secondary damage to the structure and toughness loss of the structure....

The wear resistance and dimensional stability of the aluminum casting directly affect the machine accuracy and service life; size, accuracy of mold and surface roughness of various pumps' impellers, bodies and inner cavities have direct impacts on the working efficiency of pump and...

Aluminum alloy die casting infiltration is a new type of casting process, the main principle is to use polystyrene foam to make exactly the same foam model as casts, and then brushed aluminum alloy die casts which was impregnated with special refractory coating, drying, packing, pouring, the metal solution...
