Luma Gold Plated Molybdenum Wire Luma Gold Plated Molybdenum Wire For some applications molybdenum wire has to be plated to meet special requirements. This may be for instance to protect the wire from corrosion or to solder it to other metals. Example of Applications: Antennas Wire qualities: 710/60 710/67 Connectors Properties of bare Molybdenum wire Electronic tubes Purity 99.9% Mo Melting point 2620 °C Density 10.14 g/cm3 Specific electrical resistance at 20 °C 0.052 Ohm x mm2/m Modulus of elasticity at 20 °C 320 kN/mm2 Description Treatment before plating: Etched of strike: Gold Type Treatment before plating: Etched Type of strike: Nickel Wire dimensions: 20 – 500 microns Diameter tolerances: +/- 4% by weight as standard Minimum +/- 1.5% available on request Gold coat thickness: 3 – 5% by weight as standard. The coat thickness can be adjusted to meet your requirements.
