在波音公司或发动机生产厂家从钛原料生产厂家购人的钛材量中，实际飞机用量只是其中的一部分．即使一架巨型喷气式客机，其钛原料的购入量相当于30t～40t，而一架波音777客机（B777）的钛原料购入量约为60，如果月产量能够达到7架，B777将消耗钛原料约5000t．目前世界钛加工材
The actual use of aircraft is only part of the amount of titanium purchased from manufacturers of titanium raw materials by either Boeing or engine manufacturers. Even a giant jet airliner purchases titanium equivalent at 30t to 40t while a Boeing 777 airliner (B777) buys titanium at about 60. If the monthly output can reach seven, the B777 Consumption of titanium raw materials about 5000t. The world’s titanium processing materials
