Sintered Bronze Products (SAE 841)
Rigid, temperature resistant and high strength parts formed through the process of sintering, or powder metallurgy, sintered bronze parts are available in a number of different types.
SAE 841 Sintered Bronze parts are available as
Powder metallurgy uses a number of different metals including aluminum, copper, nickel, brass, steel, stainless steel, nickel and titanium in the fabrication of powdered metal parts.
Powdered metal parts have a proven record of unexcelled wear resistance and long life. They hold closer tolerances, and through oil impregnation they can even be made self-lubricating. The smoother action and self-dampening features that powdered metal parts provide assure a quiet operation.
Our Sintered Bronze cannot be used as filter material. If you require filter material,
give us a call, we’ll be happy to provide information and refer you to a company that provides this material.
Each of these rigid, temperature resistant and high strength bushings are formed through the process of powder metallurgy.
POWDER METALLURGY HAS THREE BASIC STEPS:
- First, the metal, in this case, bronze or bronze alloy, is made into a powdered form, either through methods such as grinding, chemical decomposition, or the most common atomization.
- Second, at room temperature, the metallic powder is poured into a die or mold cavity and compacted under great pressure in order to adhere the particles.
- Third, the metal part is 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. As a result, bearings and wear plates are often fabricated from sintered bronze.
Powdered metal provides both enhanced strength and flexibility. Additionally, these metals offer a cost effective production process that includes oil impregnation or permanent lubrication

SAE 841 SINTERED BRONZE TYPICAL USES:
Heavy industry uses sintered bronze as machinery components, as self-lubricating pump parts, and as turbine blades. The military depends on sintered bronze for reliability in weapons and aircraft; and this technique is also used to fabricate exotic materials for space vehicles.
Strong and resilient sintered bronze is also used in shock absorbers, in home appliances, automobiles and most commonly, it is used as bearings or bushings.
Sintered bronze parts can be produced in large quantities with consistent properties and sizes for a wide variety of applications.
