What kinds of PM machine parts are there?

What kinds of PM machine parts are there? It is the knowledge brought to you today that powder metallurgy can produce many kinds of parts. What are the specific types of mechanical parts? Let's take a look.

1: Structural parts

Gears and various stressed parts made of copper, iron, copper alloy, aluminum alloy, etc.

Sintered metal oil-bearing. Iron base and copper base porous bearings with porosity of 15%~25% are filled with lubricating oil.

Copper back sintered alloy bearing. The first layer is steel back, and the second layer is sintered copper aluminum alloy.

DU, DX bearings, etc.

Application of structural parts: automobiles, machine tools, agricultural machinery, textile machinery, instruments, sewing machines, electric tools, internal combustion engines, railway vehicles, metallurgical machinery, tape recorders, video recorders, micro-motors, etc.

2: Friction parts

Clutch plate or brake band made of steel back and iron-based or copper-based powder composition

Application of friction parts: friction components on automobiles, aircraft, tanks, engineering machinery, machine tools and power machinery.

3: Filter elements and other porous materials

Filter element. Cup-shaped, conical, cylindrical and rod-shaped products made of spherical bronze, nickel, iron, stainless steel and other metal powders with evenly distributed pores.

Quenched material. There are bars, strips and tubular products with porosity of 50% made of nickel, nickel-chromium alloy, stainless steel and other corrosion-resistant materials.

Fiber metal products. High porosity (up to 80%) products made of fine metal fibers.

Application of filter elements and other porous materials: used to filter various gases and liquids in chemical industry, machine tools, aircraft, automobiles, internal combustion engines, etc., used as porous metal filters in fluidic elements, used as porous quenching elements, sound absorption plates in aircraft, and used as filter elements for special purposes.
