一、国际上镁及镁合金的生产和应用现状 据国际镁协统计,1995～1999年西方世界镁产量徘徊在25万吨上下,而我国的镁产量1999年产量达15.7万吨,居世界第一,比1998年增长30％,其中80％用于出口。1999年西方世界金属镁的消费量为37.55万吨,比1998年增长16.4％,其消费缺口主要由我国出口弥补。 First, the international status of the production and application of magnesium and magnesium alloy According to the International Magnesium Association statistics, from 1995 to 1999 the western world production of magnesium hovered around 250,000 tons, while China’s magnesium output in 1999 reached 157,000 tons, ranking first in the world First, an increase of 30% over 1998, of which 80% was for export. In 1999, the consumption of metallic magnesium in the western world was 375,500 tons, an increase of 16.4% over 1998. The consumption gap was mostly covered by China’s exports.
