Product standard:

GB/T 8320-2003 or ASTM B 702-93

We supply tungsten copper with a variety of compositions，our WCu alloy can be almost completely dense, defect-free, fine-grained structure, and

 the air tightness of  the materials detected by the helium mass spectrometer is <5x10-9Pa /m3.s. reached the international advanced level. Below are metallographic photographs of a 70% tungsten, 30% copper alloy.
