A Comparison between Sintered Metal Components and Other Types of Components

June 7, 2021

Many equipment pieces, devices, and other products today are often comprised of different metal components. Subsequently, these metal components are made from various processes, which allow them to boast different characteristics and qualities.

Some of these metal components can be made from the powder metallurgy process. Others, alternatively, can be processed out of forging or die casting methods. What is unique about the powder metallurgy process is that it can boast numerous benefits that other processes do not manifest.

Sintered Metal Components

Sintered metal components are parts that are processed through powder metallurgy. Powder metallurgy generally covers processes that allow metal powders to be converted into useful materials and components. Through these processes, a significant amount of yield losses in manufacture can be minimised. Additionally, the whole operation costs can be cut through powder metallurgy due to reduced yield losses, less secondary machining, and lower labour needs.

As for the sintered metal components, they can easily provide tons of advantages to different industries. For one, these types of components are capable of being exposed to high temperature and extreme elements. Their electrical and magnetic properties, density, toughness, hardness, and damping can likewise be controlled effectively. Significant improvements over their tensile strength can also be seen once they are processed with high-temperature sintering. Ultimately, despite having complex and intricate details, these components can still be produced in huge quantity in just a short amount of time.

Some limitations of sintered metal components, however, include their overall size and part design. They can also be weaker when compared to forged or mould components.

Other Types of Components

Metal components can also be made from forging and die casting methods. The forging method can effectively create metal components that have different shapes and sizes. Components out of the forging process are likewise stronger than other types of components, which can be very helpful in applications that require stability all the time.

Forged components, however, also have some weaknesses. For one, they lack sufficient control over their microstructure. They likewise have to be processed for secondary machining. The process of forging cannot also produce parts with multiple types of metals.

Die casting, alternatively, is a process that forces molten metal into a mould cavity. After pouring the molten metal into the die and subsequently freezes, it still has to go through different machining operations to come up with the needed specifications. What is great about die casting is that it can produce complex shapes at a high speed. The process can likewise produce durable and dimensionally stable components. These components are also heat resistant, strong, and light.

Some notable drawbacks of die casting, on the other hand, include high costs and long lead time. Gases may likewise be trapped during the operations, which can affect the overall quality of the components.
