Custom Powder Metal Services
At Ridgway Powdered Metals, Inc., we deliver precision-engineered custom powder metal components that combine advanced technology with decades of expertise. Whether you need structural components, self-lubricating bearings, stainless steel parts, or specialized alloy solutions, our team works closely with you from initial design through full production to ensure every part meets your exact specifications.
Process Advantages
Why powder metallurgy?RPM has aggressively invested in the technology and equipment to take full advantage of PM’s many benefits — delivering precision parts that other metalworking processes simply cannot match at the same cost.
Net Shape Production
Eliminates or minimizes machining by producing parts at or close to net shape.
97%+ Material Utilization
Typically uses more than 97% of starting raw material in the finished part — minimal scrap losses.
Broad Alloy Selection
Wide variety of alloy systems — including brand-new formulations and RPM proprietary grades.
Surface Finish
Produces good surface finish — 32 RMS or better.
Heat-Treatable Materials
Provides heat-treatable materials for increased strength, wear resistance, and durability.
Controlled Porosity
Enables self-lubrication or filtration applications through controlled porosity.
Complex Geometries
Facilitates manufacture of complex or unique shapes that would be impractical or impossible with other metalworking processes.
High-Volume Production
Suited to moderate to high volume component production with long-term reliability in critical applications.
Green and Sustainable
PM is an environmentally responsible, sustainable manufacturing industry.
Cost Advantage
Minimum average savings of 30% over other metalworking technologies — often exceeding 100%.
Materials
MPIF standard and RPM proprietary gradesRPM builds parts in all standard Metal Powder Industries Federation (MPIF) grades as well as proprietary RPM grades. Material selection should be discussed with RPM Engineering prior to specifying a grade for your application.
| Material | MPIF Code | Characteristics |
|---|---|---|
| Iron | F-0000 | Electro-Magnets |
| Iron/Carbon | F-0003/F-0008 | Moderate Strength, Heat treatable |
| Iron/Copper/Carbon | FC-0200 to FC-0208 | Good strength and wear resistance, Heat treatable |
| Iron/Nickel/Carbon | FN-0200 to FN-0408 | Good impact strength and wear properties, Heat treatable |
| Alloy Steels | FLN2C-4005 to FLDN4C2-4905 | A wide variety of materials with specific properties to match the critical requirements of the application – all are Heat treatable |
| Copper Infiltrated Steel | FX-1005 to FX-2008 | Good strength, improved machinability, gas tight Heat treatable |
| Stainless Steel | SS-303, SS-304, SS-316, SS-409, SS-410, SS-430, SS-434, 17-4PH | Select the stainless grade that will satisfy your requirements for corrosion resistance, ductility, machinability, etc. |
| Copper | C-0000 | Electrical applications |
| Bronze | CT-1000 | Self-Lubricating Bearings |
| Brass | CZ-1000, CZ-2000 | Mechanical components and Hardware |
