Sintered parts: economic & technical advantages.
Economic advantages
Cost reduction of over 40%
Powder metallurgy is well suited to the requirements of large-scale component production because it uses over 97% of the raw material needed for the starting piece.
This method reduces costs by over 40% compared to other metallurgical processes.

The advantages of sintering mechanical parts compared to other technologies.
Comparison with parts produced by casting, die casting, and microcasting
- Improved accuracy and surface finish
- No blowholes
- No reworking required
Comparison with machined mechanical parts
- Elimination of a complex and costly range of products
- Reduction in machining waste and chip recycling costs
- Improved dimensional reproducibility in very large production runs
Comparison with cut and assembled parts
- Improved accuracy and surface finish
- A single-piece design replaces multiple assembled parts
Sintered mechanical parts : technical limitations.
Dimensional tolerances
The dimensions, perpendicular to the direction of compression and obtained using hardened steel or tungsten carbide tooling elements, can be achieved with tight tolerances.
Given the maximum power of the presses used in MP and the pressures required to achieve sufficient densification, the projected cross-section of a part is limited.
Industrial applications and materials of sintered parts.
Sintered mechanical parts have numerous applications in industry. Thanks to their dimensional accuracy, good mechanical strength, and cost-effectiveness, they are ideal for components such as gears, bushings, cams, sprockets, etc.
The materials used to manufacture sintered mechanical parts mainly include iron, alloy steel, bronze, and stainless steel powders, selected according to customer requirements and intended use: wear resistance, temperature resistance, corrosion resistance, etc.
