Brass and Zinc Ball Valve

Brass and Zinc Ball Valve

A brass and zinc ball valve is made of brass and zinc.

Brass is any alloy of copper and zinc; the proportions of zinc and copper can be varied to create a range of brasses with varying properties. Brass is used for applications where low friction is required. As it is softer than most other metals in general use, brass is often used in situations where it is important that sparks not be struck, as in fittings and tools around explosive gases. It is ususlly relatively resistant to tarnishing.Brass has higher malleability than copper or zinc. The relatively low melting point of brass and its flow characteristics make it a relatively easy material to cast. By varying the proportions of copper and zinc, the properties of the brass can be changed, allowing hard and soft brasses.

Zinc is used to make brass and bronze. It is also used in metal coating and rust protection, called galvanization. Zinc oxide is a common sunscreen because it can block harmful ultraviolet (UV) rays that damage skin. This same compound is also used to make white paints and to make photocopies. Zinc sulfide, another zinc compound, is used in electronic devices as a phosphor (Fos-four). Phosphor gives off light when struck by electrons. Zinc sulfide has been used on the inside of computer and television screens to produce images from your favorite TV show to computer games.
