Basic properties of tantalum alloy Ta2.5W:
Composition:W 2~3%,Nb 0.5%(max),Ta balanced
Density:16.7g/cm3
Melting point：3005℃
Extension-brittle transition temperature:＜-250℃
Chemical resistance property is equivalent to pure tantalum, even better than pure tantalum.
Mechanical properties:Ta2.5w increases the tensile strength by about 40% compared to pure tantalum, but the ductility is slightly reduced.Recrystallized hardness is 130HV
Processing characteristics:Its processing characteristics and welding performance are similar to those of pure tantalum,its eliminates stress temperature 1000℃, recrystallization temperature is1200~1300℃.
