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. Specification: Diameter, mm Difference between 2 feet, mm Inside diameter tolerance, mm Big heater element Small heater element 0.4-3.0 1 0.3 0.4-1.0 1 0.3 0.4-1.3 1 0.3 0.4-1.0 2 1 0.3 0.4-1.0 1 0.3 0.4-1.0 several stranded coils 0.3 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. 5. Products Feature: 1. Excellent Conductivity 2. Resistance of high temperature. 3. Abrasion and Erosion. 4. Suitable for making heating wires. 5. Twisted wires for coating films under vacuum and for tungsten wires in electrical light sources usage.

Cemented carbide is the term which refers to sintered composite materials composed of at least one metal carbide constituent. Tungsten Carbide (WC), Titanium Carbide (TiC),Tantalum Carbide (TaC) are common constituents. Our tungsten carbide rods are made of optimum quality raw material WC, which acts as hard phase, and the binder agent Cobalt. With powder metallurgy HIP technology, carbide rods are sintered with homogeneous microstructure including little or even no porosity, to a great extent, increasing the whole performance and properties such as hardness and bending strength. Our HF30U solid rod obtains 93 HRA hardness and at least 4000 MPa transverse rupture strength.
Cemented carbide sleeve adopts raw and auxiliary materials such as primary saturated tungsten carbide, high-purity ultra-fine cobalt powder, precise carbon blending, tilt ball milling, vacuum stirring drying, precision pressing, digital degreasing sintering and pressure sintering personalized post-processing and other advanced powder metallurgy processes. Hard alloy sleeve is widely used in special valve industry, with long service life and reliable quality.

The cemented carbide seal ring is made of tungsten carbide powder as the raw material, cobalt powder or nickel powder as the binder, pressed by a certain mold, sintered in a vacuum furnace or hydrogen reduction furnace, and made of high strength and high hardness cemented carbide material, which is not deformed and more compressive. As the most widely used mechanical seal products, cemented carbide seal ring has the characteristics of high hardness, wear resistance, corrosion resistance and so on.
Powder forming mold is to put powder into the to compress, solidify, and sinter at high temperature to form high-precision parts, which can be mass producted. The use of high-precision molds omits the cutting waste after forming and sintering, and achieves the purpose of reducing costs.
