The figure and tables shown below indicate the typical dimensional tolerances achievable in a powder metal part.
For the correct interpretation of these data, it is important to highlight that:
- These tolerances can be affected by the geometry of the component, the type of material and the manufacturing process (sintering conditions and/or complementary operations).
- In self-lubricating bushings, dimensional accuracy in diameter improves up to IT 5-7.
- In high temperature sintered materials, such as stainless steels, some soft magnetic materials and certain structural steels, dimensional accuracy is adversely affected by one IT, especially in diameter.
