Tungsten Alloy EWCe-2 vs WVMA (Doped Non-Sag Tungsten)

Tungsten Alloy · grade comparison

Tungsten Alloy EWCe-2 and WVMA (Doped Non-Sag Tungsten) are both tungsten alloy grades. WVMA (Doped Non-Sag Tungsten) is the stronger of the two: yield strength 1,900 MPa (276 ksi) against 1,100 MPa (160 ksi) for EWCe-2, about 73% more; tensile strength follows at 2,200 MPa (319 ksi) vs 1,300 MPa (189 ksi). WVMA (Doped Non-Sag Tungsten) is the more ductile: elongation 2.5% versus 2% for EWCe-2. WVMA (Doped Non-Sag Tungsten) runs hotter in service (2,000°C vs 500°C continuous).

WVMA (Doped Non-Sag Tungsten)Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
