Zinc ingot (purified metallic zinc) Zinc ingot refers to pure zinc, of course there will be impurities, but as zinc ingot, at least more than 90% purity.
Mainly used in die casting alloy, battery industry, printing and dyeing industry, medicine, rubber industry, chemical industry, zinc and other metal alloys in electroplating, spraying and other industries have been widely used.

We do all possible finishes including nickle free finishes, powder coating and lacquering.
Pure zinc ingot refers, of course, there will be impurities, but as zinc, at least more than 90% purity. Zinc uses: mainly used for die-casting alloys, batteries, printing and dyeing industry, pharmaceutical industry, rubber industry, chemical industry, an alloy of zinc and other metals in electroplating, painting and other industries are widely used.
Main Application:
(A) galvanized
Zinc has excellent resistance to atmospheric corrosion, it is mainly used for surface coating of steel and steel parts (such as galvanized sheet), widely used in automotive, construction, shipbuilding, light industry and other industries. In recent years, Western countries began to try to do directly with a zinc alloy plate roof covering material, which can be up to life 120--140 years, and then recycled, and galvanized iron roofing material as life generally 5--10 years.
(B) of the copper alloy material (such as brass)
For the automotive and machinery industries. Zinc has suitable mechanical properties. Zinc itself is not high strength and hardness, but after adding alloying elements aluminum, copper, its strength and hardness are greatly improved, especially the emergence of titanium zinc and copper, its mechanical properties close to or reach aluminum, brass , the level of gray cast iron, and its creep resistance is also significantly be improved. Thus, zinc, copper and titanium has been widely used in hardware production.
(C) zinc alloy for casting
Mainly for the casting for the automotive and light industry. Many zinc alloy processing performance are relatively good, pass processing rate of up to 60% -80%. MV excellent performance, deep drawing, and self-lubricating, extending the life of the die, the available brazing or resistance welding or arc welding (required in helium) welding, surface can be plated or coated, cutting performance is good. Under certain conditions, with excellent superplasticity.
In addition, zinc has a good anti-electromagnetic properties. Electrical conductivity of zinc is 29% for electric and copper, in the case of RF interference, zinc plate is a very effective shielding material, and because zinc is non-magnetic, suitable for housing materials and instruments and instrument parts of the coin, Meanwhile, zinc and other metal itself and the collision will not spark, suitable for underground explosion-proof equipment.
(D) for the manufacture of zinc oxide
Widely used in rubber, paint, enamel, pharmaceutical, printing, fiber and other industries.
Zinc with appropriate chemical properties. Zinc can occur with NH4CI, release H + cations. Zinc - manganese dioxide zinc batteries is the use of this feature, made with zinc alloy battery case, both the battery electrolyte container, took part in the cell reaction constitutes a battery anode. It's this performance is also widely used in the pharmaceutical industry.
Cadmium Ingot
Introduction
Cadmium and zinc are found in nature together.It is a good neutron-absorbing metal, made into rods that slow the rate of chain fission reactions in nuclear reactors, and Cadmium compounds useful in zn-cadmium batteries.Rare elements, symbol Cd.It's silver white.Melting point is 321 â??.The ratio of material to cadmium in the crust is 1000000:0.1 ~ 1000000:0.5.Cadmium Ingot is extracted from zinc ore or sulphur-cadmium ore as a by-product and is mostly used to protect other metals from corrosion and rust,� such as electroplated steel, iron products, copper, brass and other alloys.Another use is to make a bright yellow pigment called cadmium-yellow, which can be used in advanced paints and paints.
use
Used in the manufacture of alloys: as an alloy group, cadmium can be mixed into many alloys, such as hard copper alloys containing 0.5% ~ 1.0% cadmium, which have high tensile strength and wear resistance.Cadmium (98.65%) nickel (1.35%) alloys are used as bearing materials for aircraft engines.Cadmium is found in many low melting point alloys, with the famous wood fusible alloy containing 12.5% cadmium.
Cadmium rods has a large thermal neutron capture cross section so alloys containing silver (80%) indium (15%) cadmium (5%)Â can be used as control rods for atomic reactors.
Cadmium compounds have been� widely used in the manufacture of (yellow)� pigments, plastic stabilizers, phosphors, insecticides, fungicides, and paints.
