Good wear resistance and high temperature properties of tungsten sheet

In the use of diamond saw blades or drill to process high quartz content of the concrete pavement, concrete structures and high hardness , hard red granite sawing materials like high-density, high quartz content , often used to join a large number of tungsten metal powder , improved high-temperature strength and wear resistance of the carcass to improve product performance . Good wear resistance and high tungsten carbide plate of tungsten , but the high sintering temperature , generally in diamond segments carcass adding other low melting point metal powder such as copper , cobalt, nickel and other elements as the bonding phase , and add some low melting point metal tin elements to reduce the sintering temperature . In the diamond tool industry , the traditional method is the use of elemental powders obtained by mechanical mixing matrix material , due to the large proportion of tungsten , and other difficult process of mixing the powder mixing, likely to cause uneven carcass composition and organization , resulting in  Tungsten copper alloy  of the tool . In recent years, research on the application of pre- alloy powder ultrafine diamond tools carcass more and more , and achieved good results using the application or part of adding these pre- alloy powder were able to significantly improve the hardness and cutting the carcass performance . While research on the preparation of ultrafine tungsten-copper powder material , and made good sintering properties have been reported , such as tungsten, copper powder ultrafine high activity, low sintering temperature , high alloy densification , homogeneous and so on.
