Zinc ingot

Zinc ingot uses: mainly used in die casting alloy, battery industry, printing and dyeing industry, medicine, rubber industry, chemical industry, zinc and other metal alloy in electroplating, spraying and other industries to get the application.

Content of zinc ingot

1, zinc ingot can be used for galvanizing

Zinc has excellent atmospheric corrosion resistance, so it is mainly used for the surface coating of steel and steel structural parts (such as galvanized sheet), used in automobile, construction, shipbuilding, light industry and other industries. In recent years the west begins to try to use zinc alloy board to do housetop to cover material directly, its use fixed number of year can be as long as 120-140 years, and can recycle reuse, and the service life that makes housetop material with galvanized iron board is 5-10 years commonly.

2, zinc ingot used to manufacture copper alloy materials (such as brass)

Used in automobile manufacturing and machinery industry. Zinc has suitable mechanical properties. The strength and hardness of zinc itself are not high, but after the addition of aluminum, copper and other alloying elements, the strength and hardness are greatly improved, especially the appearance of zn-Cu-ti alloy, its comprehensive mechanical properties have approached or reached the level of aluminum alloy, brass, gray cast iron, its creep resistance is also greatly improved. Therefore, zinc-cu-ti alloy has been used in hardware production.

3, zinc ingot for casting zinc alloy

Mainly for die casting, used in automobile, light industry and other industries. The processing performance of many zinc alloys is relatively good, the processing rate can reach 60%-80%. Medium pressure, can carry out deep drawing, and has self-lubrication, prolong the life of the mold, can be brazed or resistance welding or arc welding (need in helium) for welding, surface can be electroplated, paint treatment, good cutting performance. It has superior superplastic energy under certain conditions.

In addition, zinc has good resistance to electromagnetic field. Zinc conductivity is 29% of the standard electrical copper, in the rf interference, zinc plate is a very shielding material, at the same time because zinc is non-magnetic, suitable for instrument parts of the material and instrument shell and money, at the same time, zinc and other metal collision will not spark, suitable for underground explosion-proof equipment.

4, zinc ingot is used to make zinc oxide, accounting for about 11%

Used in rubber, coating, enamel, medicine, printing, fiber and other industries.

5, used to manufacture dry battery, in the form of zinc cake, zinc plate, about 13%.

Zinc has suitable chemical properties. Zinc can react with NH4CI and release H+ positive ions. Zinc-manganese dioxide battery is the use of this characteristic of zinc, zinc alloy as the shell of the battery, not only the battery electrolyte container, but also participate in the battery reaction constitute the anode of the battery. Its properties are also being used in the pharmaceutical industry.

Environmental protection low temperature zinc alloy (English name: zinc alloy) : zinc ingot 98.7, 99.97, 99.99, zinc ingot content

Is a kind of environmental protection products, exported to Europe and America, can be used for centrifugal casting all kinds of jewelry, corsage, badge, belt buckle and other objects.

Zinc alloy introduction:

Zinc alloys are alloys based on zinc and composed of other elements. Common alloying elements include aluminum, copper, magnesium, cadmium, lead, titanium and other low temperature zinc alloys. Zinc alloy has low melting point, good fluidity, easy fusion welding, brazing and plastic processing, in the atmosphere, the disabled material is easy to recover and remelt; However, the creep strength is low and the size change is easily caused by natural aging. Prepared by melting method, die casting or pressure processing. According to the manufacturing process, it can be divided into casting zinc alloy and deformation zinc alloy.

Low temperature zinc alloy:

The main added elements of zinc alloy are aluminum, copper and magnesium. Zinc alloy can be divided into deformation and casting zinc alloy according to the processing technology. Casting zinc alloy has good fluidity and properties, suitable for die casting instrument, automobile parts shell, etc.

Zinc alloy handle

Ingredient quality characteristics:

1. Relative weight.

2. Casting performance is good, can die casting complex shape, thin wall parts, casting surface is smooth.

3. Surface treatment: electroplating, spraying, painting, polishing, grinding, etc.

4. When melting and die casting, no iron absorption, no corrosion, no sticking mold.

5. Good mechanical properties and properties at room temperature.

6. Low melting point, melting at 385ºC, easy to die casting.

species

The traditional die-casting zinc alloys are no. 2, 3, 4, 5 and 7, and no. 3 zinc alloy is currently used. In the 1970s, zA-8, ZA-12 and ZA-27 alloys were developed.

Zamak 3: Good fluidity and mechanical properties.

Used for casting with low mechanical strength requirements, such as toys, lamps and lanterns, decorations and some electrical parts.

Zamak 5: Good fluidity and good mechanical properties.

Applied to castings with certain requirements on mechanical strength, such as automobile parts, electromechanical parts, mechanical parts, electrical components.

Zamak 2: used for mechanical parts with special requirements for mechanical properties, high requirements for hardness, good performance and general requirements for dimensional accuracy.

ZA8: Good fluidity and dimensional stability, but poor fluidity.

It is suitable for die casting workpiece with small size, high precision and high mechanical strength, such as electrical parts.

Superloy: good fluidity, suitable for die casting thin-walled, large size, high precision, complex shape workpiece, such as electrical components and their boxes.

Different zinc alloys have different physical and mechanical properties, which provides choice space for die casting design.

Zinc alloy can be divided into casting zinc alloy and deformation zinc alloy according to the manufacturing process. The yield of cast alloy is much higher than that of deformed alloy. The following table lists the composition, properties and uses of several important zinc alloys.

Casting zinc alloy according to the casting method is divided into pressure casting zinc alloy (solidified under the action of added pressure) and gravity casting zinc alloy (only solidified under the action of gravity).

The production of pressure cast zinc alloys has increased dramatically since its introduction in the automobile industry in 1940, accounting for about 25% of total zinc consumption. Applicable technologies are being used and developed rapidly. Related talents are also increasing. The alloy system commonly used by Iron and Steel Talent network is Zn-Al-Cu-Mg system. Some impurities obviously affect the properties of die - cast zinc alloy. Therefore, the content of impurities such as iron, lead, cadmium and tin is strictly limited, with the upper limit of 0.005%, 0.004%, 0.003% and 0.02% respectively. Therefore, high-purity zinc with purity greater than 99.99% should be used as raw materials for die casting zinc alloy.

Gravity casting zinc alloys can be cast in sand, plaster or hard molds. This kind of zinc alloy not only has the characteristics of general die-casting zinc alloy, but also has high strength, good casting performance, cooling rate has no obvious effect on mechanical properties, residual and waste materials can be recycled, simple gate, not sensitive to overheat and remelting, small shrinkage rate, less porosity, electroplating, can be used by conventional finishing method.

In addition to the traditional varieties, there are Zn-1Cu-0.1Ti and Zn-22Al alloys. When the alloy is rolled, the grain boundary movement can be obstructed due to the presence of TiZn15 intermetallic compound dispersed particles aligned along the rolling direction.
