Refractory metals are a class of metals that are extraordinarily resistant to heat and wear and have extremely high melting points. Reactive metals have a strong affinity for oxygen and nitrogen at elevated temperatures and are highly resistant to corrosion at low temperatures.

  • Precious Metals
    Precious metals may seem unlikely as engineering materials, but the same expensive metals used for coinage and jewelry also satisfy applications requiring the ultimate in corrosion resistance or electrical conductivity. Three subgroups make up the entire family of precious metals: silver and silver...

    . Copper and Brass tubes. TELLURIUM COPPER. Rods, plates, hexes. SILVER TUNGSTEN. Rectangles, squares, rounds. GRAPHITE. Graphite electrodes are by far the most popular EDM electrodes used in the United States. Here at Saturn we feel that it is important to give our customers what they want and in doing...
  • Metals and Ceramics
    , and mullite. Adding titanium, zirconium, or hafnium to standard silver-based braze alloys forms an activated alloy. By firing such an alloy onto ceramic surfaces at 800 to 1,000 C in vacuum or argon, the braze will wet directly onto the ceramic through migration of the active metal toward the ceramic...
  • Refractory Metals
    and another wire alloyed with 5% rhenium. Nozzle throats of forged and machined unalloyed tungsten have been used in solid-fuel rocket engines; at one time, throats were machined from porous consolidations of tungsten powder that were infiltrated with silver for exposure to gases at temperatures near...
  • Shielding
    of silver ink printed on 5-mil-thick polyester. After printing, a curing process removes nonconductive solvents. The result is a homogeneous shield that does not crack or delaminate when bent. The shield can be mechanically fastened and grounded with solder tabs. The cost is about the same...

    faster, creating the potential for the dishing of copper lines on a wafer. In contrast, as Figure 4 shows, when the second-step chemistry was used as the test solution, the OCPs of the three electrodes changed. (For each of these Tafel plots, the potentials are plotted versus saturated silver/silver...
  • Guidelines for Selecting the Right Brazing Alloy
    copper and its alloys, this alloy group may also be used on silver, tungsten and molybdenum. Copper phosphorous alloys are not used on ferrous or nickel-containing alloys because iron and nickel form glass-like compounds with phosphorous, and the joints produced may be brittle. Silver - Copper...
  • Successful Plasma Cutting Counts on Consumables
    . The electrode carries the current from the torch to the plate. It’s a slender piece made of copper or silver and contains hafnium or tungsten. These materials have been found to be excellent conductors of electricity. The electricity comes from the machine out to the torch and goes into a cathode block...
