For an oil well with high mineralization degree, fluid in the well usually contains a large number of mineral elements, and the mineral elements can generate destructive influence on an oil pipe, a sucker rod and other equipment in the well. The invention discloses a scaling inhibition alloy. The alloy is prepared from the raw material components including, by mass, 65wt%-75wt% of Cu, 20wt%-25wt% of Ni, 2wt%-5wt% of Co and 0.5wt%-5wt% of Fe. The invention further discloses a preparation method of the alloy. The alloy achieves the scaling inhibition effect through the electrochemical action between the alloy and fluid, the scaling inhibition effect is good, the production efficiency is improved, the service life of equipment is prolonged, and economic losses are reduced. Compared with the conventional scaling inhibition alloy containing a zinc system, the alloy does not contain zinc and lead elements and is more environment-friendly. 对于高矿化度的油井，井内流体通常含有大量的矿物质元素，这些元素会对油管、抽油杆和井中的其他设备产生破坏性影响。本发明公开了一种阻垢合金，原料成分按质量百分
