Abstract

The invention discloses CuZnNiSi alloy, a preparation method thereof and a method for preparing strips using the same. The method comprises the following steps: weighting 10-20% of zinc, 0.462-1.89% of nickel, wherein silicon accounts for 0.11-0.42% of the total amount of copper silicon alloy and the balance is copper; placing copper and nickel into an intermediate frequency induction melting furnace, heating to 1250-1300 DEG C and melting; after melting, adding zinc, copper silicon alloy, uniformly stirring up and casting; obtaining CuZnNiSi alloy using homogenization processing. The CuZnNiSi alloy strips can be obtained by hot rolling, quenching, rolling, annealing and tension-leveling. The CuZnNiSi alloy is high in strength and conductivity.
