Wire EDM Blocks

May 17, 2016

General Carbide has expanded its operations to produce more than 40 standard and custom sizes of WEDM blocks for a range of stamping and fabricating applications. To help ensure that blocks are of the highest metallurgical quality and reach customers intact and quickly, the company processes every order in sinter-HIP furnaces, ships the blocks in durable packaging, guarantees turnaround of 3 to 5 business days and tracks shipments door-to-door.

“Providing superior grades and more WEDM options is the result of listening to customers and prospects, making a significant capital investment,” said Mona Pappafava-Ray, General Carbide’s president and CEO. “Our submicron grain size of tungsten carbide particles is ideal for wear resistant grades capable of withstanding moderate impact loads. In contrast, our 4-micron carbide particle grain size and use of tantalum carbide yield a WEDM block that offers the highest resistance to galling.”

  • galling


    Condition whereby excessive friction between high spots results in localized welding with subsequent spalling and further roughening of the rubbing surface(s) of one or both of two mating parts.

  • tungsten carbide ( WC)

    tungsten carbide ( WC)

    Intermetallic compound consisting of equal parts, by atomic weight, of tungsten and carbon. Sometimes tungsten carbide is used in reference to the cemented tungsten carbide material with cobalt added and/or with titanium carbide or tantalum carbide added. Thus, the tungsten carbide may be used to refer to pure tungsten carbide as well as co-bonded tungsten carbide, which may or may not contain added titanium carbide and/or tantalum carbide.
