Metalworking
The discovery and use of iron to make tools and weapons was one of the most important advances in civilization.Some historians consider the use of iron to be one of the distinguishing characteristics separating civilization from barbarism because the new tools increased productivity dramatically and led to so many new advances.Compared to bronze,iron tools were less brittle,could hold sharper edges,and held edges for a longer time without sharpening.Most importantly,iron ore was much easier to locate than copper and tin,making iron tools cheaper and more readily available.By 1000 BC iron tools were being made that were as good as the best ones of bronze; by 500 BC iron had largely supplanted bronze from Europe to Asia.The expense and scarcity of bronze had restricted its use to the elite and wealthy.Iron tools and weapons were available to nearly everyone.
-----------------------
Metallurgy
The use of iron spread throughout the Mediterranean,Middle East,and Asia during the first millennium BC,and some areas became especially adept at the new science.Certain compounds added to the molten metal increased the strength of the resulting tools.New forging techniques also resulted in better tools.The best iron workers made superior weapons that were an important advantage in battle.

铁的发现和使用制造工具和武器是文明的最重要的进步之一.一些历史学家考虑使用铁的到是有区别的特征分开的文明的一个从野蛮ad.因为新的工具增加的生产力戏剧地和领导到因而多数新的前进.比拟为青铜,铁工具是比较不易碎,可以支撑较鲜明的边缘,而且不拿着了边缘达比较长的时间之久尖锐而.最重要地,铁矿石加对找出胜于铜和锡是比较容易的,使铁成为工具更廉宜和更不迟疑可得.在西元前 1000 年之前铁工具正在被做那是像青铜的最好一些一样的好;在西元前 500 年之前铁已经从欧洲到亚洲主要地排挤掉青铜.青铜的费用和缺乏已经限制对精华的它使用和富有的.铁用工具工作,而且武器是可得的到几乎每个人.
-----------------------
冶金铁的使用在地中海,中东和亚洲各处传布在那的时候第一的西元前一千年,而且一些区域在新的科学尤其变成熟练.某化合物增加到增加产生的工具力量的溶化金属.新的锻链技术也造成较好的工具.最好铁工人制造了战争的一个重要的利益上好的武器.
