Embodiment Construction
[0013] An environmentally friendly zinc-nickel-nickel alloy material, which contains chemical element components and mass percentages: nickel 11.5-12.9, cobalt 0.6-0.9, manganese 2.3-2.5, iron 0.15-0.18, bismuth 0.05-0.09, zinc 21.5-21.9, Si0.5-0.6, Sb0.03-0.05, and the balance is copper.
[0014] The production method of described environment-friendly zinc-nickel-nickel alloy material is as follows:
[0015] (1) Prepare pure copper and scrap copper as the source of copper matrix in a ratio of 1:0.6, add pure copper into the furnace to melt, remove impurities, deoxidize, use refining agent for one-time refining, add alloy components for alloying, and then add Scrap copper melting, adding refining agent for secondary refining, testing and adjusting the content of chemical elements to pass, casting, post-casting heat treatment, etc.;
[0016] (2) The order of batches of alloying elements put into the furnace during the alloying process is: (1) zinc; (2) nickel; (3) iron, cobalt...
