Sinter Bonding in Powder Metallurgy: What is it All About?

January 14, 2020

Powder metallurgy has been playing a huge role in the creation of metallic materials and components. It is a form of technology where powder used for creating metallic or even ceramic materials are moulded into specific shapes and dimensions. The whole process of metal creation through powder metallurgy reduces cost, energy, and waste.

The formation of metallic products, or powder metallurgy, is possible through sinter bonding. Sinter bonding is a heating process where metal powder is compacted that creates powerful links between powder particles. In some cases, these powder particles are placed into a high-temperature environment to develop the bond, but not so high that the parts will melt into ashes.

The Importance of Sinter Bonding

Powder metallurgy industries have been using sinter bonding to join two parts together. What makes powder metallurgy effective is that it can hold two parts together without compromising the quality of the material and their respective functionalities. Sinter bonding can create a two-part metal assembly with accompanied useful benefits, just like welding two materials together.

Sinter Bonding and Its Applications

The general idea for sinter bonding is to create and fuse parts for easier assembly with other products or tools. This fused part may also be called as a single sintered assembly, where the involved components can still do their respective functionality without affecting each other. Sinter bonding can produce parts that are multifunctional in purpose.

With sinter bonding, you are guaranteed to reduce the number of components found in your assembly, reduce cost, create complex and complicated shapes, and isolate a material in a specific location.

Keep in mind, however, that sinter bonding doesn’t work on every assembly. If you want to merge two different assemblies, they must possess the right properties that can make them work together. For example, you can use a nickel-iron for the exterior and a copper-steel for the interior. These two different components work with each other very well since the copper will just expand while the nickel will shrink during the sintering process.

Benefits of Sinter Bonding

With the applications mentioned for sinter bonding, here are some benefits that you can get from this type of metal production.

  • Wide Moulding Capability: What makes sinter bonding suitable to metal production is its ability to be moulded to any type of shape. Sinter bonding can be applied even to complicated shapes.
  • Eliminates Scrap: With sinter bonding, you can create parts that don’t require any secondary machining. Subsequently, sinter bonding eliminates scraps that make your work cost-effective.
  • Stronger Formation: The ability of sinter bonding to fuse two different materials makes the whole assembly stronger than ever. The new assembly is as strong as the original parts.
  • Add-ons Not Required: Two sintered parts don’t require any more parts for them to be linked together. Sinter bonding will only have to rely on the unique qualities and properties of these two parts.
