Molybdenum wire is used in profile cutting, H2 furnace, heater rod guide hooks, mandrels, wires, lead, etc. Molybdenum is applied in the manufacturing of high-temperature-resistant equipment such as supports, guide rods, and furnace heating rods.
Tensile strength of molybdenum wire: Tensile strength is a measure of a material's ability to resist breaking under radial loads. It is measured by the weight that a unit cross-sectional area can bear, such as in British units as PSI (pounds per square inch) or in metric units as N/mm2 (newtons per square millimeter). Copper is a material with low tensile strength (245N/mm2), whereas molybdenum has high tensile strength (1930N/mm2). The tensile strength of wire depends on the material chosen, as well as the heat treatment and stretching processes. Wires are sometimes categorized as "soft wire" and "hard wire," each having its advantages for different equipment and applications.

The diameter of molybdenum wire directly affects processing accuracy and efficiency. Smaller-diameter molybdenum wire can be cut in narrow routes, suitable for precise processing, but has lower strength and is prone to breakage. Larger-diameter molybdenum wire can withstand high loads, ideal for high-intensity processing tasks, but may compromise some processing precision. Therefore, when selecting the diameter of molybdenum wire, it's necessary to decide based on specific processing requirements.

During wire cutting processing, the wire needs to possess various beneficial characteristics. The coating should have high interlayer peel strength under high temperatures and heavy loads. Molybdenum, due to its properties, is widely regarded as a material for metal thermal spraying technology. It is widely used in the thermal spraying on surfaces of automotive parts such as piston rings, synchronizer rings, and gearboxes.

Electrical characteristics of wire EDM molybdenum wire:
Modern wire-cutting power supplies place strict demands on the electrical wire. They must withstand high cutting currents of over 700 amperes in peak or over 45 amperes in average, with efficient energy transfer to provide the pulse current needed to achieve high surface finish (above 0.2Ra). This depends on the wire's resistance or conductivity. Copper is one of the materials with high conductivity, used as a benchmark for other materials. The conductivity of copper is rated as IACS (Annealed Copper Standard), while brass has a conductivity of 20%.
