Combined with the previous background on the corrosion characteristics of metals in radiation environments and radiation-resistant stable metals, the price difference of this type of special metal is very large, and the price difference of products of different categories, specifications, and standards can reach dozens of times. 1. Basic price differences of different categories of ordinary radiation-resistant aluminum alloys: The unit price is about 20-50 yuan/kg, which is the entry price for this type of material. Inconel 718 nickel-based alloy: The unit price of domestic ordinary round rods is about 140-180 yuan/kg, and the price of aviation-grade products can reach 240-260 yuan/kg. Hastelloy C276: The unit price is generally 200-400 yuan/kg, and the price of special customized parts is higher. Nuclear grade zirconium alloy: The unit price can reach thousands of yuan/kilogram, which is dozens of times that of ordinary metals for civilian use. 2. Material standards, the core factors affecting the price difference: The price difference between ordinary industrial grade and nuclear grade/aerospace grade materials of the same brand can reach 2-3 times. Processing form: The basic prices of plates and bars are relatively low, while the prices of forgings and precision customized parts will rise significantly. Procurement channels: The unit price of small-volume retail sales will be more than 30% higher than that of large-volume industrial purchases. The latest market conditions in July 2026 show that the purchase cost of industrial-grade ordinary radiation-resistant metals is only about 1/10 of that of nuclear-grade high-end radiation-resistant special metals, and the price difference is very significant.
