zinc alloy ball valve

A zinc alloy ball valve is a ball valve that uses zink alloy as its material. This design can takes advantages of both the structure of ball valve and the properties of zinc alloy. The follow is the basic information about them.
Zinc, is a metallic chemical element. Zinc production includes froth flotation of the ore, roasting, and final extraction using electricity.
Many alloys contain zinc, including brass, an alloy of zinc and copper. Other metals long known to form binary alloys with zinc are aluminium, antimony, bismuth, gold, iron, lead, mercury, silver, tin, magnesium, cobalt, nickel, tellurium and sodium.
The metal is most commonly used as an anti-corrosion agent. Galvanization, which is the coating of iron or steel to protect the metals against corrosion, is the most familiar form of using zinc in this way.
Zinc is more reactive than iron or steel and thus will attract almost all local oxidation until it completely corrodes away. The zinc is applied electrochemically or as molten zinc by hot-dip galvanizing or spraying.
A widely used alloy which contains zinc is brass, in which copper is alloyed with anywhere from 3% to 45% zinc, depending upon the type of brass. Brass is generally more ductile and stronger than copper and has superior corrosion resistance. These properties make it useful in water valves. Other widely used alloys that contain zinc include nickel silver, typewriter metal, soft and aluminium solder, and commercial bronze. Alloys of primarily zinc with small amounts of copper, aluminium, and magnesium are useful in die casting, especially in the automotive, electrical, and hardware industries. These alloys are marketed under the name Zamak. An example of this is zinc aluminium. The low melting point together with the low viscosity of the alloy makes the production of small and intricate shapes possible. The low working temperature leads to rapid cooling of the cast products and therefore fast assembly is possible.
