Mo Wire
---- Monocrystalline
Silicon
growing furnace application
Molybdenum is a transition metal. The pure metal is silvery white in color and very
hard, and has one of the highest melting points 26200C of all pure elements. Due to its
excellent thermal conductivity and low electrical resistivity, molybdenum is also used
widely in many industry. The low thermal expansion of molybdenum makes it a frequently
used material in the electronics industry for semiconductor supports and glass
melting. Molybdenum has good corrosion resistance particularly to hydrochloric acid. Molybdenum is not subject to hydrogen embitterment.
We focus on providing high quality Molybdenum products, such as
wires, plate, bar, Molybdenum machined
parts and fabrications so on.
Applying for extra high temperature
environment,
we strictly control the O,C,Fe elements from raw material, improving
high temperature creep strength and
Tensile strength,
hence the material high temperature stabilityproperty is much higher
than pure Mo wire from other suppliers.

With over decades
experiences in material, we could produce many varieties of Molybdenum
and its alloy fabricated parts for our customers' ready for use.
