(http://www.zcmim.com/)Powder metallurgy can was prepared by
ordinary smelting method to preparation of special materials, and can produce
various kinds of precision mechanical parts, powder metallurgy forming features
not only, also labor-saving.
Physical properties of powder metallurgy,
such as particle shape, particle size, particle size distribution and specific
surface area. Common spherical, granular, flake like and needle like. The
linear size of a single powder particle is its size, according to different size,
divided into several levels, each level of powder in accordance with the
quality, quantity or volume percentage is its size distribution.
The total surface area per unit mass of
powder is its specific surface area. When the powder is compressed into a certain
shape and the ability to maintain this shape in subsequent processing, the
higher the compressive strength obtained under a certain pressure, the better
the formability of powder metallurgy.
