The benefits of using powder metallurgy

History of powder metallurgy

Size of powders 0. The products of metallurgy can have limited shapes and features. The powder thus produced will be in its purest form. The technique of powder metallurgy combines unique technical features with cost effectiveness and generally used to produce sintered hard metals known as carbides or tungsten carbides. This produced a powder with varying particle size. Elemental powders like iron and copper are more compressible and produce pressed compacts with good strength. The majority of presses typically compact gear faces up to 3 inches. The porosity-induced lack of density kept PM gears from being adopted for high-strength applications until about 15 years ago.

One-way single press and single sintering is improving with selectively densifying areas of critical importance and leaving the core—or non-critical areas—at a lower density. By using powder metallurgy, parts can be produced with infiltration and impregnation of other materials to obtain special characteristics which are needed for specific application.

Powder Metallurgy What is Powder Metallurgy? Powders can be tailor-made to meet the most important property requirements. Generally, PM is competitive with casting, machining, and forging, and often associated with the aerospace, power, and medical industries.

economics of powder metallurgy

Powders might not be able to handle as much force as some of the AHSS, but the process allows for porosity and complex shapes that can reduce cost, material, and weight.

It is a versatile, cost-effective, and constantly expanding technology that is rapidly gaining worldwide popularity. Bycemented carbides and impregnated lubricants in ball bearings started changing the machine industry.
