Abstract
Disclose is a copper alloy for a laser cladding valve seat. the copper alloy may include an amount of about 15.0 to 25.0 wt % of Ni, an amount of about 1.0 to 4.0 wt % of Si, an amount of about 0.5 to 1.0 wt % of B, an amount of about 1.0 to 2.0 wt % of Cr, an amount of about 5.0 to 15.0 wt % of Co, an amount of about 2.0 to 20.0 wt % of Mo, an amount of about 0.1 to 0.5 wt % of Ti and the balance Cu, all the wt % based on the total weight of the copper alloy. Particularly, the copper alloy may not include Fe, and may include Ti silicacide. Further disclosed is a laser cladding valve seat including the copper alloy, which does not generate cracks and is excellent in wear resistance.
