The powder metal technology is an obvious process technology for manufacturing large batches of uniform quality with specific accuracy requirements and material properties.

      • Components for compressors typically have particular high precision requirements. A subsequent calibration of tolerances ensures the high precision requirements on the connecting rod, where the parallelism tolerance is 35 µm with a hole tolerance of only 6 µm.
        The valve plates are typically designed with multi holes / channels, this can be included in the pressing operation, thereby achieving net-shape design without subsequent processing.

      • FJ Sintermetal manufactures components for professional machines for maintenance of parks and forestry. Components for lawn mowers and clutch parts for chainsaws can profitably be manufactured in powder metal. These components are typically hardened to higher hardness due to requirements of high mechanical and wear properties.
      • GEARS

      • The sintering process is particularly suitable for the manufacturing of gear components. Gears in one or more levels can be manufactured directly in the tool with high precision. A quality class 8 can typically be achieved and a module down to about 0.4 can be manufactured in powder metal depending on the number of teeth.

      • Powder metal components are found in many appliances and machines used in the household. Among others are components for sewing machines often made ​​of sintered metal due the precision in the process. Design is a keyword and materials could typically be stainless steel, or made with a coating, if a neat and uniform surface or a particular color is required.

      • FJ Sintermetal manufactures various components for hydraulic pumps. These pumps are characterized by operating at high speed and high pressure that is at 270 bar, which requires a high precision and strength of the sintered components.

      • The powder metal process is used for manufacturing locking systems. Components for locking of doors are usually small with complex designs and in order to ensure high level of performance, tight tolerances are generally reqiuired. Components are often made of stainless steel or coated in order to obtain good corrosion protection.
      • MOTORS

      • Components for electrical motors are typically manufactured in soft magnetic materials. Materials used can be pure ferrite or silicon and phosphorus alloyed. Depending on the desired magnetic properties soft magnetic composites (Soft Magnetic Composites = SMC)can be used, resulting in a 3-D high-flux induction and high resistivity, low core loss comparable to that of conventional laminated steel sheets.
      • OTHER

      • The powder metal technology is a suitable manufacturing method for many components within fittings, filters and other parts designed for industrial use. The cheapest and simplest form of sintered components are achieved simply by pressing and sintering without subsequent machining.

      • Many tool parts can conveniently be manufactured in powder metal when requiring uniformity and narrow tolerances. Components for Power Tools require high mechanical properties and high precision. Clamps with special trays can also conveniently be manufactured in powder metal due to the many design options. Positioning systems for machining require good material properties with high precision.
      • PUMPS

      • Sintered components are often used as a basis for pump components. With a subsequent calibration, fine tolerances are achieved which are required for achieving a good vibration-free pump operation. Bushings are typically made in special designs of bronze and sealing systems in stainless steel. The components can be treated with a galvanic coating to increase corrosion resistance.
      • WINDOWS

      • For automation of opening and closing operation of windows powder metal components are typically used as the mechanical operating element. Reduction gear motors are examples of this. The advantage is that you can manufacture precision components at low cost in large series. The components are usually surface coated to increase corrosion resistance.

    • There is a wide range of design choices for sintered metal components, and their areas of use are continually being enlarged.

      Whether the powder metal component is manufactured in steel, stainless steel, bronze or maybe soft magnetic materials is often determined by the design and end usage of the component. Our powder metal components are often used in mechanical applications but powder metal components are actually used in everything from transmissions and fastenings to electromagnetic products.

      In cooperation with our customers we continually discover new opportunities for using sintered metal parts and the benefits and advantages of the process. Do not hesitate to contact us if you have questions concerning choice of material for your component.


      Steel alloys are the materials most commonly used in manufacturing sintered metal components.
      The many options for alloying the pure iron powder mean that materials can be adapted to offer the specific properties the customer needs.

      The strength of solid steel can also be achieved with sintered metal.

      Stainless steel

      FJ Sintermetal uses several types of powder to manufacture stainless steel sintered components.

      A selection of your options can be seen below.

      316 An austenitic and non-magnetic stainless steel powder with good corrosion resistance and mechanical properties. The most commonly used powder.

      410 A martensitic, ferro-magnetic stainless steel powder that can become extremely hard and therefore has good wear resistance.

      430 A ferrittic stainless steel powder with enhanced magnetic and corrosion resistant properties in comparison with 410. Used for applications where there is a need for corrosion resistance and magnetic properties.


      Sintered bronze is mainly used for bronze bearings, but due to the good frictional properties of the material, it has many other areas of use.

      Items made of sintered bronze are often calibrated and can therefore be manufactured to tolerances down to tolerance grade IT6.

      Soft magnetic materials

      Sintered metal can be used with great advantage for applications that requires soft magnetic properties, such as magnetic cores or other products that have electromagnetic components.

      Sintered metal adds a number of advantages to these types of applications in several areas, such as design, uniformity, quality, and price.
        • PROCESS

        • The sinter metal process involves compressing metal powder in a precision tool and then heating or sintering the component to create metallurgical bonds. The sintered component is often the end component or product and addtitional operations are not necessary.

          This is one of the main benefits of the sinter metal process and a major competetive advantage when comparing the process with other component manufacturing processes like machining or plastics.
