MHC alloy wire and pure molybdenum wire tensile strength of less than 1100 ℃ annealing, the strength remained unchanged, but in the above 1 200 ℃ annealed with the annealing temperature increase strength tends to decrease, but the strength of the alloy wire has MHC higher than pure molybdenum wire strength.
