APPLICATIONS FOR OPM SINTERED MECHANICAL PARTS.
OPM, the expert in sintered mechanical parts.
Motor
- Pole pieces
- SMC stator (soft magnetic compound)
Which industrial sectors use sintered mechanical parts?
Historically, powder metallurgy has been driven by the automotive industry, which accounts for 60 to 80% of sintered mechanical parts. However, the widespread introduction of electronics has led to a significant reduction in the proportion of mechanical parts used in this industry.
At the same time, other sectors such as household appliances, construction, and tools are seeing rapid and steady growth in the use of mechanical parts. This allows us to say that sintering techniques will continue to surprise us and have a bright future ahead of them.

Advantages of sintering and materials used.
Sintering offers numerous advantages for the manufacture of precision mechanical parts: it enables the production of complex parts in large series with an excellent level of repeatability. This process also offers great design freedom and allows mechanical performance to be optimized according to functional requirements.
Sintered parts are made from metal powders, mainly based on iron, stainless steel, copper, bronze, or specific alloys. Find out more about the choice of materials for sintered mechanical parts on our dedicated page.
