As tungsten heavy alloy's high density, high melting point, small capacity, excellent hardness, superior wearing resistance, high ultimate tensile strength, etc. Tungsten heavy alloy rod is increasingly welcomed by public.
Features: high melting point and low vapor pressure, low thermal expansion, high thermal conductivity, is mainly used for structural parts of quartz industry, high-temperature furnace heating element, and so the cathode electrolysis.
High-temperature refractory metals such as molybdenum- and tungsten-based materials are essential in today's sapphire crystal growing technologies and are widely used for crucibles, hot-zone shieldings or heaters.
If the heat generated cannot be diffused and is instead reserved, it will reach the melting point of PTFE and quickly be destroyed, so the PV value gives a general indicator of the operating limits.
In order to manufacture high purity niobium ingots by electron beam purification, it is best to purify them at high power under high vacuum to effectively remove impurities, especially gases and high melting-point metals.
The manufacturing process of tungsten copper rod is as follows: press the refractory metal, sinter the pressed compact at a high temperature, and infiltrate it with copper.
Although initially defined by the freezing point of water(and later the melting point of ice), the Celsius scale is now officially a derived scale, defined in relation to the Kelvin temperature scale.
It has poor thermal and electrical properties and finds applications in the manufacture of fusible alloys, a range of materials with low melting points which are suitable for various applications including solders and thermal fuses.
