How to correctly choose metal powder metallurgy materials

Author:


Metal powder metallurgy has a wide range of applications and a wide variety of materials. How to choose suitable metal powder metallurgy materials?
Powder metallurgy friction reducing materials are also called sintered friction reducing materials. It is prepared by immersing lubricating oil into the pores of materials or adding friction reducers or solid lubricants to the material composition. The friction coefficient between material surfaces is small, and it has a long service life and high reliability when lubricating oil is limited; under dry friction conditions, it has a self-lubricating effect by relying on itself or the lubricant contained on the surface. Widely used in bearings, bearing bushes or face seals.
Powder metallurgy porous materials, also known as porous sintered materials. It is formed by molding and sintering spherical or irregular-shaped metal or alloy powder. The pores in the material are criss-crossed and interconnected. The porosity is generally 30%-60%, the pore size is 1-100μM, and it has good permeability, thermal conductivity, high temperature and low temperature resistance, thermal shock resistance and medium corrosion resistance. Used to manufacture filters, porous electrodes, fire extinguishing devices, antifreeze devices, etc.
Metal powder metallurgy structural materials, also known as sintered structural materials. It can withstand tensile, compression, torsion and other loads, and can work under friction and wear conditions. Due to the presence of residual pores in the material, its plasticity

MIM products usually have the following characteristics

The most suitable wall thickness for MIM is no more than 6mm. Thicker outer wall is acceptable, but the cost will be increased due to the longer processing time and extra material used. In addition, u

What is the density and strength of MIM products?

The density of a typical MIM is theoretically higher than 98%. Specific density characteristics depend on the choice of material, but it is very close to precision materials.

Metal injection molding technology in detail

Metal injection molding (referred to as MIM) is a technology combining powder metallurgy and injection molding, which breaks through the traditional powder metallurgy product shape and strength limitations, also breaks through the strength limitations of die casting, breaks through the material flow restrictions of stamping molds, and breaks through precision. Mass production restrictions for casting and high cost constraints for turned parts.

The market competition pattern of 3D printed metal powder may change

The market competition pattern of 3D printing metal powder will change as more companies enter or increase their production and R & D efforts in the field of metal powder. In 2016, GKN, Oerlikon and Alcoa made active strategic plans.

Rich variety of raw materials, and the variety of domestic powder metallurgy products has been expanded

In terms of raw materials, at present, the main raw materials of powder metallurgy in China are not only reduced iron powder, electrolytic copper powder, etc., and domestic production of atomized iron powder, stainless steel powder, high-speed steel powder, coated powder and various element metal MIM powder, Ceramic powders can basically meet the needs of domestic production of high-strength parts, and can also produce raw material powders for special purposes, which greatly expands the variety of powder metallurgy products, but there is still a large gap in quality and variety from abroad.
