What is Sintered Metal?

Conventional sintering and high-temperature sintering are different shades of the same color. In our eyes, for sintering to be considered high-temperature, it needs to happen at around 100-250 F hotter (in the case of iron-heavy materials) than the standard sintering temp for a particular metal.

Pressing And Sintering Of Powder Parts

Powder Sintering . Powder sintering involves raising the temperature of the green compact, (pressed powder part), to a certain level and keeping it at that temperature for a certain amount of time. The sintering temperature is usually between 70% and 90% of the melting point of the powder metal. This will cause bonding mechanisms to occur between powder particles pressed together in the compact.
