Core Performance Advantages
High Purity (>= 99.95%) for Stable Electrical & Thermal Behavior
Lower-grade molybdenum often contains elevated levels of carbon, oxygen, or iron impurities, causing erratic electrical conductivity, localized hot spots, and premature high-temperature embrittlement. By enforcing strict chemical control from raw powder to the final drawing stage, our wires ensure uniform electrical resistivity and predictable performance across demanding thermal cycles.
Extreme High-Temperature Resistance
With a melting point of 2,623 C, molybdenum vastly outperforms conventional stainless steels and nickel-based alloys in operating environments exceeding 1,000 C. It retains outstanding mechanical strength in vacuum and protective inert atmospheres (such as hydrogen or argon), making it an optimal choice for heating elements and furnace internal structures.
Low Thermal Expansion for Superior Dimensional Precision
Featuring a low thermal expansion coefficient of 4.8 x 10^-6 / K, our molybdenum wire undergoes minimal thermal distortion during rapid heating and cooling cycles. In precision mold-making and cutting applications, this stability prevents dimensional drift, guaranteeing tight tolerances and superior surface finishes.
