φ0.18 molybdenum cutting wire

Introduction to Molybdenum Cutting Wire

Classification:


  • Molybdenum cutting wire is a high-performance wire material widely used in precision wire cutting, particularly in wire EDM (Electrical Discharge Machining) and semiconductor, electronic component, and precision mold manufacturing industries. It is known for its excellent mechanical strength, electrical conductivity, and high-temperature resistance.

    Material Characteristics

    Made primarily from high-purity molybdenum (Mo), this wire features:

    • High tensile strength

    • Good wear resistance

    • Low elongation

    • Excellent thermal conductivity

    • High melting point (~2620°C)

    These properties allow the wire to maintain dimensional stability and cutting performance even under high electrical discharge and thermal stress.

    Types and Surface Treatments

    Molybdenum cutting wire is typically available in various diameters (commonly 0.18 mm, 0.20 mm, 0.25 mm, etc.) and surface finishes:

    • Plain molybdenum wire

    • Coated molybdenum wire (e.g., with graphite or polymer coatings to enhance lubricity and reduce wire loss)

    • Black or white molybdenum wire (referring to oxide-coated or cleaned surfaces)

    Applications

    • Wire-cut EDM machines for high-precision part manufacturing

    • Cutting magnetic materials, such as NdFeB (neodymium magnets)

    • Microfabrication in electronics and watchmaking

    • Precision die and mold production

    Advantages

    • Stable performance during long cutting cycles

    • High cutting precision and surface quality

    • Good resistance to wire breakage

    • Lower wire consumption compared to brass wire in certain applications

    • Reusable in multi-pass or reciprocating wire cutting systems
