Embodiment 1
[0016] A platinum alloy for 1800-degree smelting, Ru-containing, high-conductivity and corrosion-resistant electrical contact materials. In terms of weight percentage, the chemical composition of the alloy is: Ru: 2.6wt.%, Ti: 1.4wt.%, Ge: 0.6wt.%, Mn: 0.3wt.%, Al: 0.7wt.%, Pd: 0.6wt .%, W: 0.3wt.%, Pr: 0.6wt.%, B: 0.3wt.%, the balance is platinum. The preparation method of the alloy: add the above-mentioned raw materials into an induction furnace under an argon atmosphere, and use a silicon carbide crucible. Induction heating to 1800 degrees to form an alloy solution, and use the electromagnetic effect to fully stir for about 10 minutes. The alloy liquid is poured into a water glass mold at 1800 degrees for 10 minutes for casting. The ingot is deformed at room temperature, and the amount of rolling in each pass is 12%; every 3 passes of rolling requires an intermediate heat treatment to eliminate work hardening, the process is: 640 degrees, 3.0 hours; after rolling The fin...
