Magnesium Particles (Mg 9999)
At present, most high-speed railways with a speed per hour over 300 km in China adopt the third generation of copper and magnesium alloy contact wire; while the those with a speed per hours lower than 300km basically adopt the second generation of copper and silver contact wire or the third generation of copper and tin alloy contact wire. Through performance comparison, the tensile strength and electric conductivity of copper and magnesium alloy contact wire are higher than that of the cooper and tin alloy contact wire. In addition, the fourth generation of ultra-fine crystal strengthened copper and magnesium alloy contact wire independently developed by China boasts extremely improved major performance index and has been put into industrialized products. High-purity magnesium has been massively used in this product. For the convenience of production of copper and magnesium alloy, high-purity magnesium is added in the form of particles.
