Summary:The invention discloses a spraying rod for roadways. The spraying rod comprises a metal body subjected to heat treatment and made of alloy material; the alloy material is composed of, by weight, 1-2% of Si, 0.5% of Se, 0.7% of As, 0.8% of Mg, 0.2% of Au, 0.9% of Ba and the balance Cu and inevitable impurities; the heat treatment comprises the steps of 1, heating the alloy material to 665 DEG C at the rate of 25 DEG C/min and preserving the temperature for 3.5 hours; 2, cooling the alloy material to the indoor temperature at the rate of 35 DEG C/min; 3, heating the alloy material to 765 DEG C at the rate of 20 DEG C/min and preserving the temperature for 2.5 hours; 4, cooling the alloy material to the indoor temperature at the rate of 15 DEG C/min. According to the invention, the performance of the metal body is good, and the service life is long.
