Nickel aluminum bronze plastic mould material and preparation method thereof

The invention discloses a nickel aluminum bronze plastic mould material. The nickel aluminum bronze plastic mould material comprises the following components by weight percent: 10-12% of Al, 3-5% of Ni, 3-5% of Fe, 1-2% of Mn, 0.2-0.3% of Ti, 0.2-0.3% of B, 0.05-0.1% of Zn and the balance of Cu. The material provided by the invention is high in compression strength and excellent in heat conduction, heat dissipation, thermal fatigue resistance, abrasive resistance and corrosion resistance; the service life of the mould is 3-6 times higher than that of the traditional iron alloy steel plastic mould material; the material is excellent in cold and heat process molding and smooth in mould processing surface, is used for high polymer plastic forming, is high in plastic product size precision, clear in ornamentation and beautiful on the surface and has higher performance than that of the iron alloy mould material. The invention also discloses a preparation method of the nickel aluminum bronze plastic mould material.
