I am trying to locate an S-N diagram for a sintered tungsten powdered
alloy with the following general characteristics:
90% W + 10% Cu-Ni-Fe
Density 16.85 - 17.25 g/cc
Rc hardness = 32 max.
UTS 120 ksi (827 MPa) min.
YTS 80 ksi (551 MPa) min. (0.2% offset)
Elongation 10% min in 1" gage length.
I have an application with a 400 MPa fluctuating stress, and I am trying
to establish the endurance limit for the above material to determine if
there is infinite life. Any information would be helpful. Thank You,

Tungsten is an environmentally friendly, durable and hard material, its most important property is its density of 19.25g/cm3, which is just about the same density as gold (19.3g/cm3). The common understanding of tungsten alloy shapes means tungsten alloy shape, but in fact, different component, production technology, and application, calls for different tungsten alloy shapes.
