The process of powder metallurgy has (3) basic steps:
First, the metal, in this case, bronze or bronze alloy, is made into a powdered form. This can be achieved by a number of methods including grinding, chemical decomposition and the most common atomization.
The metallic powder is then poured into a die or mold cavity and compacted under great pressure in order to adhere the particles. This occurs at room temperature.
The metal part is then inserted into a furnace where the extreme heat fuses the metal particles together to form a rigid, high strength and porous component. This part of the process is called sintering.
The resulting porosity of the sintered parts makes powder metal products especially useful in lubricating applications and as a result, bearings and wear plates are often fabricated from sintered bronze. Powdered metal offer both strength and flexibility. Additionally, they offer a cost effective production process that includes oil impregnation or permanent lubrication.
