Apart From Zinc Alloy 3, Which Other Zinc Alloys Are There?
Zinc base alloy commonly used in rubber mould casting.
- Zinc aluminium M solder alloy is composed of 95%zinc 5% aluminium that contains remarkable coating corrosion resistance.
- It is soldered with 95ZN-5AL corrosion resistance hence superior to that obtained with other solders.
Slush cast alloy.
- It is a high purpose engineered product because the alloy is manufactured to provide a high fluidity casting material, capable of producing a good surface definition when cast
- It contains approximately 5% aluminium and 95% zinc hence it is used primarily for the use of hollow casting.
Spin cast zinc alloy-J1
- It is a lead-free zinc alloy that frequently works well in spin cast thus silicone moulds for designs with thin cross section or maximum detail.
- It contains property grain refiners for improved flow into the mould.
Commercial zinc alloy.
- It is made up of 20% aluminium and 80% of zinc.
- During spin casting application, commercial zinc alloy provides an excellent casting outcome.
- It is one of the most commonly used alloys in musical instruments since it is made up of 12% aluminium and 88% zinc.
- A mixture of lead and tin is known to make zinc alloy with low melting point thus used to join electrical components, pipes and other applications.
- Zinc/aluminium solder is an alloy used as a coating sprayed onto steel.
Can You Die Cast Zinc Alloy 3?
Zinc alloy 3 is considered the first choice for die casting because it offers an excellent finishing result for plating, painting and chromate treatment.
Zinc alloy 3 is the easiest alloy to cast and also offers the best desirable physical and mechanical properties.
It also has a superb cast ability and the long-lasting dimensional stability.
When comparing to other die cast metals, zinc alloy 3 provides the higher precision with lower tooling cost thus it is most versatile metal.

What Are The Benefits Of Zinc Alloy 3?
Zinc alloy 3 are mostly used as antifriction materials in bearing linings hence they are good for the casting
They are also used in printing industry [zincography].
Zinc alloy are also used in pressure die casting to produce structural and decorative components of motor vehicles and other objects.
They are also used in some of the technology for the manufacture of goods by deep stamping.
Are There Limitations Of Zinc Alloy 3?
Zinc alloy 3 has a poor mechanical property at elevated temperature hence resistance in corrosive acidic and alkaline media.
What Are There Properties Of Zinc Alloy 3?
Zinc alloy 3 has excellent combination of the mechanical properties such as;
- Corrosion resistance
- Good thermal conductivity
Where Can You Use Zinc Alloy 3?
We can use zinc alloy 3 for;
- Chromate treatments.
- Stamping dies and die casting.
- They are also used in medical equipment.
What Is There Chemical Composition Of Zinc Alloy 3?
Zinc alloy is made up from a composition of;
- Cadmium[max]-0.04 Aluminium-3.0-4.5
Zinc alloy 3 is the most commonly preferred alloy when it comes to die casting.
How Does Zinc Alloy 3 Compare To Aluminium Alloy?
Zinc alloy 3 is a substance formed of two or more different chemical components while aluminium alloy is a chemical component as a metal.
Die cast made from zinc alloy 3 last longer due to its strength compared to aluminium die cast.
Zinc alloy 3 has a low melting temperature hence it requires lower pressures for casting thus allows die cast to long last compared to aluminium alloy.
Another advantage of using zinc alloy 3 is that zinc 3 is great for casting with intricate details and thin walls.
Zinc alloy is used when trimming and finishing work is needed hence the thermal shock is reduced by a lower pressure during casting.
Are There Standards Specifications Of Zinc Alloy 3?
