Kind Code:
A
Abstract:
A specifically defined powder composition is provided wherein there is a requirement that the specified lubricant always be liquid at room temperature. Such powder composition contains coarse iron or iron-based powder having an average particle size between 75 and 300 μm wherein less than 10% of the powder particles have a size below 45 μm and the amount of particles above 212 μm is above 20%, and as a lubricant at least one non-drying oil or a vegetable or animal based fatty acid having a crystalline melting point below 25° C., and a viscosity (η) at 40° C. above 15 mPas, wherein said viscosity is temperature dependent according to the following formula: 10 log η=k/T+C, wherein k is the slope, T is the temperature in degrees Kelvin, and C is a constant, in an amount between 0.04 and 0.4% by weight of the composition and optional additives. The slope preferably is above 800.
