tungsten mesh is a woven wire mesh that features warp and weft (woof / filling) wires interlaced at right angles to each other. Plain woven wire mesh, twill woven wire mesh and dutch woven wire mesh are available.
Tungsten has the highest melting point of all metals and is 1.7 times heavier than lead. It is found in scheelite (CaWO4) and wolframite [(Fe,Mn)WO4].
The metal has superior tensile strength and resistivity and is extremely durable. It can withstand high temperatures of 3400 degrees and has excellent impact resistance. It is used as a heating element for a vacuum furnace and radiation shielding.
It is also a great material for filtering or sieving materials in acid, alkali environmental conditions because of its corrosion resistance. It is used in hydrogen making, chemical industries and scientific research labs.
OXY-GON manufactures tungsten and molybdenum heating elements in both mesh and weave configurations. These elements are based on continuous interlocked molybdenum & tungsten wire coils which are heated and then move independently of each other.
The interlocked nature of these elements greatly reduces mechanical and thermal stresses which results in longer element life. tungsten mesh heating elements are available in cylindrical or flat panel designs and can be used for single- or three-phase power operation. They are designed with a variety of resistance and power leads which can be manipulated to maximize the efficiency of the heating process. The top and bottom bands are also key design factors.
