Gemei typically adopts the powder metallurgy method for production: first, tungsten powder or molybdenum powder is formed through powder compaction, then sintered to obtain slabs. The slabs are subsequently rolled via processes such as hot rolling, warm rolling, and cold rolling to produce sheets of different thicknesses. Annealing treatment can also be carried out as needed to eliminate internal stresses and prevent recrystallization. The company’s tungsten, molybdenum, and their alloy sheets feature excellent quality and reliable performance, are sold both domestically and internationally, and are widely used in fields such as semiconductors, medical care, and photovoltaics.

Tungsten Sheets: Characterized by high density, high melting point, excellent thermal and electrical conductivity, high strength, and creep resistance.
Molybdenum Sheets: Possess relatively high melting point, density, hardness, and strength, along with low thermal expansion coefficient and electrical resistivity. They also exhibit good chemical stability, high-temperature creep resistance, and corrosion resistance.
Electronics and Semiconductor Industry: Can be used to manufacture electric light source parts, electron vacuum devices, sputtering targets, etc.
Aerospace Field: Suitable for producing heat insulation screens, connectors, and other components for engines, exhaust systems, etc.
Medical Field: Applicable to medical diagnostic and therapeutic equipment.
Chemical Industry: Can serve as a material for corrosion-resistant components.
Other Fields: Also used in heat insulation screens and heating elements of high-temperature furnaces, as well as in optical instruments.
