PURPOSE: To suppress erosion and wear of parts to low by forming a part of suction in contact with molten metal of a composite material containing the specific quantity of Co and the balance of Ti (alloy) and ceramic particles with inevitable impurities.
CONSTITUTION: At least a part in contact with the molten metal is made of the composite material containing 0.1-20wt.% Co and the balance Ti (Alloy) and the ceramic particles with the inevitable impurities. This composite material is made by adding the ceramics particles having high strength and high hardness to the Ti (alloy) having excellent erosion resistance to molten non-ferrous metal and excellent impact resistance and possesses the erosion resistance, impact resistance and wear resistance at the same time. By this method, as the part in contact with the molten metal is formed with this composite material, the injecting parts for die casting machine having long service life and excellent workability can be obtd.
