Common materials for constant speed drive shaft forgings
While closed die forging is applied for almost all the metal materials, in actual production, only part of the materials are used for the different characteristics. The material used is one of the main factors that affect the cost of the forgings. Let’s take a look at some of the common materials used in closed die forgings.
When it comes to closed die forging, steel is by far the most common material used. Alloy steel, carbon steel, and stainless steel are all used depending on what the forging is used for. Stainless steel material is often used for components that require corrosion resistance and rust resistance. Alloy steel and carbon steel are the most widely used in closed die forging process for its competitive price and easy deformation.
Aluminum is popular due to its low density, high strength, and easy machining. It is widely used in closed die forging process especially for the automotive and aerospace industries. Although it is commonly used in the aerospace and automotive industries, it is a challenge for domestic forging due to the fact that it is easily deformed after forging.But heat treatment can help to improve the hardness and other properties.
Copper or Brass
Copper or brass is also commonly used in closed die forging, which is the most expensive of the three materials that we have discussed. Copper forging or brass forging is most commonly used for valve and pump fittings.
