How lead is made material, used, processing,

BackgroundThe Manufacturing ProcessByproducts/WasteThe FutureLead is a dense, soft, low-melting metal. It is an important component of batteries, and about 75% of the world's lead production is consumed by the battery industry. Lead is the densest common metal except for gold, and this quality makes it effective in sound barriers and as a shield against X-rays. Lead resists corrosion by water, so it has long been used in the plumbing industry. It is also added to paints, and it makes a long-lastin在madehow上查看更多信息
