The main alternative rare earth materials due to insufficient supply of rare earth or rare earth high prices at home and abroad to seek alternative materials and related technology, materials and technology to be replaced upgrading, with a better price.

Analysis mainly has the following substitution pattern:

1, resource substitution: resource-consuming countries to diversify supply, alternative supply China will gradually form a pattern of the United States, Australia, Canada, Vietnam, India and other countries of supply.
2. Alternative formats: producer services on the part of the manufacturing sector instead.
3, raw material substitution: with rare earth materials production outside of China rare earth salts, oxides, metals, alloys, etc.
4, material substitution: cost-effective alternative to lower material cost materials, energy materials to replace energy-intensive materials, low (no) material contaminated materials instead of high pollution.
5, disruptive alternative and improved replacement.
6. Technical alternatives: a new generation technology to replace the old technology.
7, equipped with an alternative: a new generation of high efficiency, low cost, green production equipment replace the old generation equipment.
8, the system alternative: a comprehensive alternative to the equipment from materials to technology, such as solar power to replace fossil fuel generation.

Material substitution effect is generally positive, beneficial, such as rare earth NdFeB ferrite magnet technology to replace the indicators, and other breakthrough energy product promotion, greatly reducing the weight of the magnet, volume, with NdFeB magnets device, the device uses a significant improvement in performance, enhance economic and environmental benefit. Because of supply and prices, resulting in a device already NdFeB changed back to be replaced ferrite, which is harmful to the reverse substitution, the long-term and comprehensive benefits to see is worth the candle.
