3.1 grade and supply status
3.1.1 Product grade and supply status in Table 1.
Table 1 grades and supply
Product grades GSF90 GSF93 GSF95 GSF97 GSU90 GSU93 GSU95 GSM90
Supply state sintered state
Product grades GWF90 GWF93 GWF95 GWF97 GWU90 GWU93 GWU95 -
Supply state Sintering state Heat treatment state
3.1.2 Grade indicates rule. G (high tungsten basis weight) S/W (supply status, S is "sintered" state; W is "sintering heat treatment" state)
F/U/M (bonding phase, F is nickel iron; U is nickel copper; M is molybdenum nickel iron) 90/93/95/97 (nominal content of tungsten)
Example. GSU95 indicates that the supply status is sintered, with nickel-copper as the binder phase, and the tungsten content is 95% of the tungsten-based high specific gravity alloy.
