W1 99.95% Pure Tungsten Plate Polished Surface with Thickness 1.0mm to 100mm
Pure tungsten Polished Plates are available in our factory.
Pure Tungsten has high melting temperature, high density, low vapor pressure, low thermal expansion combined with good thermal conductivity, sufficient electrical resistance, high modulus of elasticity.
Tungsten Plate Sizes:
Thickness: 1.0mm - 100mm
Width: 50mm - 450mm
Length: 50mm - 1000mm
Pure Tungsten Polished Plates Applications
For sapphire crystal growth furnace, high-purity, high- density, no internal-crack tungsten crucible with
other features of exact measurement and smooth surface has decisive influence on success ratio of
seed growth, quality control of pulling crystal, metamictization pot-committed and service life during
sapphire growth process, and we are willing to be checked by professional units.
