Tungsten products available from AM&F include tungsten alloys, thoriated tungsten, and pressed and sintered tungsten. Customers can...
• Wear Resistance of Gas Nitrided Astaloy CrLTM Sintered Steel
  ). For all the tests the counterfacing material has been a sphere of tungsten. carbide of 6 mm diameter, with a hardness of at least 1600 HV, representing the static partner. The. wearable materials were the rotating disks of sintered steel. The evaluation of the wear rate has been. done through...
• Screen Classifying Cutter Allows Recycling of Tungsten Heavy Alloys
  in that they do not melt, but are compacted from powder into shapes and sintered to full density, after which they are machined and finished. Scrap is generated as a result of compaction, of sawing of large blocks, and other process scrap. Aerojet experimented with techniques to reclaim tungsten heavy alloys...
• Powder metalstake on new shapes
  is compacted and sintered in a hydrogen atmosphere. Then a 50% tungsten-50% copper core is inserted into the body and sintered again in hydrogen. Heat sinks made this way are thermally efficient and cost comparatively little to make. MIM GRAND PRIZE. A body assembly in a current-to-pressure (I/P...
• Carbide Design in Wear Resistant Powder Materials
  One area where powder metallurgy has proven to be superior to other means of manufacturing is wear resistant structures. Highly wear resistant high speed steel powders are commonly used in both HIPped and pressed and sintered forms. The carbide size and structure obtained depends both on production...
• Variability of Feedstock Viscosity and Its Correlation with Dimensional Variability of Green Powder Injection Moulded Components
  are with the Center. increasing the mixing speed increased mixture homogeneity. for. Innovative. Sintered. Products,. Penn. State. The study states that feedstock homogeneity can be. University, 147 Research West, University Park, PA. predicted by observing the torque values during feedstock. 16802, USA...
• Performance Characteristics of a Newly Developed Machinability Additive for PM Applications
  that improves the machinability of PM components with no detrimental effect on sintered strength, no staining, and no negative impact on the corrosion resistance of ferrous PM components. Results obtained from turning and drilling tests on common Fe-Cu-C and prealloyed Mo-Ni materials are presented...
• Refractory Hard Metals
  Refractory hard metals (RHMs) are a ceramiclike class of materials made from metal-carbide particles bonded together by a metal matrix. Often classified as ceramics and sometimes called cemented or sintered carbides, these metals were developed for extreme hardness and wear resistance. The RHMs...
• Bringing Powdered Metal Blending In-House, Rotary-Style
  shapes. Compacted powder not yet sintered is termed "green," and is subject to breakage if improperly handled. Broken pieces are loaded into a Pin Mill, also from Munson, reducing them into powders which are screened and blended with virgin powders up to certain percentages, depending on the blend...
• Metal Injection Molding of Co-28Cr-6Mo
  unless second phase particles are. The effect of sintering temperature on the density of Co-28Cr-. present in the matrix or at the grain boundaries [5]. 6Mo is shown in Figure 4 for samples sintered in 50% H2/50%. N2. The gas-atomized powder gave higher sintered densities at. Carbon, oxygen...
