A TRADE-OFF BETWEEN MECHANICAL STRENGTH AND EROSIVE WEAR RESISTANCE IN ALSI12CUMGNI ALLOY USED TO MANUFACTURE FAN BLADES FOR UNDERGROUND MINES

A Trade-Off between Mechanical Strength and Erosive Wear Resistance in AlSi12CuMgNi Alloy Used to Manufacture Fan Blades for Underground Mines

The axial fan blades used in underground mines are usually manufactured in AlSi12CuMgNi bl2420pt alloy (EN AC 48000).They must have a high mechanical strength to withstand the stresses resulting from the rotation speed of the rotor and a high resistance to erosive wear caused by suspended particles from underground mining and transport operations.T
