Product Description

Kefeng's Copper tungsten (CuW, WCu) has been regarded as a highly conductive and erasion resistant composite material that is extensively used as copper tungsten electrodes for EDM machining and resistance welding, electrical contacts in high voltage applications, and heat sinks and other electronic packaging materials in thermal applications.

 

The most common tungsten/copper ratios are WCu 70/30, WCu 75/25, WCu 80/20 and 90/10.  The range of available compositions is from Cu 50 wt.% to Cu 90 wt.%. Our tungsten copper product range includes copper tungsten rod, foil, sheet, plate, tube, tungsten copper rod and machined parts. We are capable of producing copper tungsten plates and sheets with a range of thickness from 0.05mm to 50mm. We also offer copper tungsten rods with diameters from 1.0mm to 127mm or more.

As an ISO-accredited tungsten alloy products manufacturer, Kefeng is capable of offering various types of tugnsten copper that meet a consistently high standard. We have the capacity to provide a reasonable lead time and handle large-volume sale.  We produce various sizes, shapes and
inished parts in forms as wire, rod, bar, sheet, ,strip, foil, sheet, plate, tubing, blanks, semi-finished and custom finished parts or according with
ustomer's drawing paper.

Certification: Corporation is ISO9001 Certified, SGS approved and has been manufacturing the highest quality tungsten alloy metals for over 28 years.
