mim metal powder metallurgy process performance

mim metal powder metallurgy process performance including liquidity, filling properties, compression resistance and formability.

1. The charge characteristics

Means in the absence of external conditions, the tightness of the accumulation of powder free time. Often the bulk density or bulk density expressed. The size of the particles of the powder filling characteristics, shape and surface properties related.

2. Liquidity

Refers to the powder flowability, time used 50 grams of powder from a standard funnel flow time representation. Granule adhesion of liquidity by.

3. Compression

It indicates the ability of the powder metallurgy in the pressing process is compacted under pressure by a predetermined unit achieved green density expressed in standard mold, measured under the conditions specified lubrication. Factors affecting powder compressibility particulate plastic or micro-hardness, ductility metal powder than the hard, brittle material compression is good; the shape and structure of the particles also affects the compressibility of the powder.

4. formability

Refers to the powder compaction, the compact's ability to maintain a predetermined shape, the smallest unit capable of forming a powder compaction pressure, or by a strength of compacts to measure. Formability affected particle shape and structure.
