    Among them, the composition of the 2-17 type alloy is others, and the magnetic energy product of the alloy is . Rare earth cobalt hard magnetic alloys are suitable for applications requiring small magnets and high magnetic field strength, such as precision DC motors, household appliances, magnetic b...

  • Classification of copper-tungsten alloy

    04 Apr 2019

    Since the two metals of tungsten and copper are incompatible with each other, the tungsten-copper alloy has low expansion property of tungsten, abrasion resistance, corrosion resistance, high electrical and thermal conductivity with copper, and is suitable for various mechanical processes. Tungsten-...
