polished/ground moly electrode:
Molybdenum electrode is electrodes made of material molybdenum, by applying its unique advantagestemperature resistance, continuous surface, stable edges good electrical conductivity, excellent corrosion-resistance -- to improve its entire quality and using age. Molybdenum electrode is silver gray metallic luster. It is isostatic pressed to forge to various types after sintering with medium frequency furnace and then turning, rolling, planning and milling. Meanwhile, the quality is unchanged, which can be seen from external and internal aspects, such as no lose side, no lose corner, and no crackle and divide layer. Thus, the surface of the molybdenum electrode is smooth and compact.
Molybdenum electrode can be used for glass industry,andwork in the glass solution with the temperature of 1300�C. Molybdenum electrode is used as electro-heat equipment of the glass fiber kiln. It is an important part in rare earth industry. Its density is more than or equal to 10g/m3, and its purity can reach 99.5%.

Molybdenum Heat Shield:
As thermal insulation components, molybdenum heat shield and molybdenum covers play a important role for heat blocking and reflecting in sapphire growth furnace. A high purity, precisely sized, smoothly clean, easy assembly and appropriately designed heat shield is significant for crystal pulling quality.
As the heat-shield parts in the sapphire growth furnace, the most decisive function of molybdenum reflection shield is to prevent and reflect the heat in the furnace. Heat-shield parts with high-density, exact-measurement, smooth-surface, convenient-assembly and reasonable-design has great significance in improving the crystal-pulling.

2. Dimensions and Tolerances of tungsten wire:
Tungsten wires diameters are generally expressed in terms of inches or mils (thousandths of an inch). For thin wires from. 001 inches up to. 020 inches in diameter, the diameter of the wire is measured by weight per unit length. That is, the weight expressed in mg of a 200 mm length of wire.
The standard diameter tolerance is: � 3% of the weight measurement. Closer tolerances are available, depending upon the application for the wire product.

Note: Different diameter and length are available for your 99.95% pure stranded tungsten wire.
3. Straightness of tungsten wire:
Wire may be finished in the unstraightened or as drawn condition and is controlled to Bango's internal standards, In addition, wire can be straightened via mechanical or heat treating processes. Typically, the measure of the straightness of a tungsten wire is obtained by cutting a ten inch long piece of wire and allowing it to lie on a flat clean surface. The maximum deviation from a straight line along its length is the quantitative measure of its straightness. In general, as the degree of straightness increases, tensile strength decreases.
4. Quality and Finish:
Wire is free of scratches, kinks and distortions insofar as they are harmful to the intended end use of the product. Surface finish is supplied in the black, as drawn condition, where drawing lubricants and oxides are retained on the surface, or in the cleaned condition by firing in hydrogen or electrochemical etching.
