Tungsten Steel Nails For Snow Tires JX8-15-1 Metal Injection Molding

According to different uses, tungsten alloys are divided into hard alloys, high-density alloys, metal sweating materials, contact materials, electronic and electric light source materials.

Doped tungsten wire is to add about 1% of silicon, aluminum and potassium oxides to tungsten powder. During the process of vertical melting (self-resistance sintering), the additive potassium oxide volatilizes and forms pores inside the material. The pores are elongated axially after processing; after annealing, the elongated pores form diffused bubbles parallel to the wire axis. This diffused bubble is commonly known as potassium bubble. Potassium bubble hinders the lateral growth of tungsten grains, improves the high-temperature anti-sagging performance of tungsten, and can also improve the room temperature plasticity after recrystallization, which is conducive to winding and transportation and storage. China's doped tungsten wire has three grades of WAl1, WAl2, and WAl3 according to the high-temperature creep value.

In W-ThO2 alloys, the addition of an appropriate amount of dispersed ThO2 particles with good thermal stability can not only reduce the electron work function, but also inhibit the growth of tungsten grains, so that the material has a very high recrystallization temperature, excellent high temperature strength and creep resistance. Tungsten-thorium alloy is not only a widely used thermal electron emission material, but also an excellent electrode material.

In tungsten-rhenium alloy, the addition of rhenium can not only improve the material strength, increase the recrystallization temperature of the alloy by about 200-400℃, make the plasticity good after secondary recrystallization, slow grain growth, but also significantly reduce the plastic-brittle transition temperature. If the added rhenium exceeds 30%, it will damage the processing properties of the alloy. Tungsten-rhenium alloy also has a high thermoelectric potential. At 2200℃, its thermoelectric potential is linearly related to temperature. The measurement temperature of tungsten-rhenium thermocouple can be as high as 3000℃, which is an excellent high-temperature thermocouple material.
