SAE 841 Sintered Bronze Products & Parts
What is sintered bronze? Sintered bronze parts are rigid, temperature-resistant, and high-strength parts formed through the process of sintering or powder metallurgy. They are available in a number of different types,
including:
SAE 841 Sintered Bronze parts are available as
Powder metallurgy uses several different metals, including aluminum, copper, nickel, brass, steel, stainless steel, nickel, and titanium, to fabricate 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 SAE 841 sintered bronze material cannot be used as a filter. If you require filter material, give us a call, and we’ll be happy to refer you to a company that can provide it for you.
Each of these rigid, temperature-resistant, and high-strength sintered bronze bushings is formed through 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 to adhere to 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 SAE 841 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 APPLICABLE SPECIFICATIONS:
- ASTM - B438, Grade 1, Type II
- MPIF - CT-1000-K26
- Military - MIL-B-5687D, Type I, Grade I (This spec only applies to bushings and washers. MIL-B-5687D, Type I, Grade I must be requested at the time of quotation. Call us for more information.)
SAE 841 SINTERED BRONZE TYPICAL USES:
Heavy industry uses sintered bronze machinery components, self-lubricating pump parts, and turbine blades. The military depends on sintered bronze products for reliability in weapons and aircraft, and this technique is also used to fabricate exotic materials for space vehicles.
Strong and resilient SAE 841 sintered bronze parts are also used in shock absorbers, home appliances, and automobiles, but they are most commonly used as sintered bronze bearings or bushings.
Sintered bronze parts can be produced in large quantities with consistent material properties and sizes for various applications.
