Our tungsten filament, tungsten boat and molybdenum boat have excellent temperature loading performance, conductivity, low vapor pressure and relatively high melting point. At the same time, the corrosion resistance and material purity (the purity of tungsten and molybdenum is over 99.95%) can prevent the substrate from being polluted. The products are used in the field of vacuum heating, including tungsten filament, tungsten coil, tungsten heater, tungsten stranded wire, electron gun filament, ion source filament, EB filament, tungsten boat, molybdenum boat, tungsten molybdenum crucible, etc.

We can customize and process tungsten filament, tungsten heating wire, tungsten coil, tungsten boat and molybdenum boat for various specifications and precision vacuum coating according to drawings or objects. We have many years of processing experience in the refractory metal industry. In the aspect of tungsten and molybdenum deep processing, hengmi relies on the advantages of technology and experience, and the tolerance is controlled at 0.001mm. The products are applied in automobile manufacturing, mechanical manufacturing, aerospace, and semiconducting Vacuum coating and optical coating fields such as body, lighting, mobile phone, computer, flat panel display, etc.
