AZ Series Alloys | High strength, good ductility, excellent casting characteristics | Commonly used in automotive and electronics industries |
Aluminum Alloys | Higher melting point, good strength-to-weight ratio | Widely used in various industries including automotive and aerospace |
Zinc Alloys | Good corrosion resistance, lower strength compared to magnesium alloys | Often used in die casting for parts requiring good surface finish and corrosion resistance |
Magnesium alloys are used in many areas. Some examples are:
Car parts
Airplane parts
Electronic housings
Textiles
Building materials
Military gear
Magnesium die casting alloys have many benefits:
Very light (about 1.8g/cm³)
Strong for their weight
Conduct heat well (150-180 W/m·K)
Over 90% can be recycled
These features make magnesium alloys great for parts that must be strong but light, like wheel hubs and engine parts.

Why Choose These Materials
Key Properties for HPDC
Picking the right materials is important for hpdc die casting. Each alloy has special features that help make strong and detailed parts. Aluminum alloy is known for being easy to pour and very strong. This means the melted metal can fill tricky molds fast and evenly. The table below shows how different aluminum alloys compare in important ways:
Alloy Type | Fluidity | Strength | Thermal Conductivity | Additional Properties |
|---|---|---|---|---|
Al-Si Alloys | Very good | Good | Moderate | Wear-resistant, corrosion-resistant |
Al-Si-Cu Alloys | Good | Better | High | Handles high thermal loads |
Al-Mg Alloys | Moderate | Superior | High | Lightweight, excellent corrosion resistance |
A413 | Superior | Moderate | Enhanced | Reduced porosity, improved fluidity |
These features help the alloys make thin parts that stay strong. High fluidity lets the metal reach every part of the mold. Good thermal conductivity helps parts cool down fast and evenly. Corrosion resistance keeps parts working well, even in hard places.

Mold Materials in High Pressure Die Casting
Common Mold Materials
Manufacturers need strong mold materials to make good HPDC parts. Most HPDC molds use special steel grades. Tool steel is the best choice for molds. It can take high heat and be used many times. H13 steel is used a lot because it is very hard and handles heat well. P20 steel is also common and works for medium-size jobs.
The table below explains why tool steel is important for HPDC molds:
Property | Description |
|---|---|
Exceptional hardness | Tool steel stays sharp and keeps its shape for many uses. |
Temperature stability | Hot-work steel stays strong even when it gets very hot. |
Wear resistance | Carbide in steel helps molds last longer and keep parts good. |
Dimensional reliability | Steel does not bend and keeps parts the right size. |
Toughness | Some types, like S7, can take hits and do not crack. |
Heat-treat flexibility | Tool steel can be made harder or softer for different jobs. |
Some molds use beryllium-copper alloys for inserts. These alloys help cool the mold and make it last longer. But steel is still the main mold material. It gives the best mix of strength, toughness, and price.
Mold Selection Criteria
The right mold material depends on how many parts you need and how hard the part is to make. For small jobs, makers use aluminum or soft steel molds. For medium jobs, pre-hardened P20 steel is a good pick. For big jobs, hardened tool steel like H13 is best.
Production Volume | Recommended Mold Material |
|---|---|
Low (under 1,000 parts) | Aluminum or soft steel |
Medium (up to 500k) | Pre-hardened P20 steel |
High (500k+) | Hardened tool steel (H13, stainless grades) |
MORELUX uses special ways to get molds ready and check quality. Their team watches every step to stop mistakes. They use sensors and pressure checks to make the process better. These steps help every mold meet tough rules and make good parts each time.
Tip: Using good mold materials and careful work helps molds last longer and make better parts.
Material Selection for HPDC Die Casting
Application Requirements
Choosing the right material for hpdc die casting depends on what the part must do. Engineers think about how strong and light the part should be. They also look at how the part will be used. Car and airplane parts need to be strong but not heavy. HPDC can make parts with tricky shapes and high detail. This is important for cars and planes.
The table below shows what matters most when picking materials for different jobs:
Factor | Description |
|---|---|
Material Properties | Strength, ductility, and weight help parts work well in cars and planes. |
HPDC Process Efficiency | Making complex shapes and precise parts is key for design needs. |
Alloy Selection | Picking aluminum or magnesium alloys changes how the part performs and its cost. |
Process Parameters | How the die casting process is set up affects the quality of the finished part. |
Lightweight Materials | Lighter parts help cars and planes use less fuel and work better. |
Non-Heat Treatable Alloys | Some alloys do not need extra heat treatment, saving time and money. |
Sustainability is important too. Many companies use recycled aluminum in hpdc. This helps the earth and saves energy. New tools like digital simulation and 3D printing help design better molds. These tools also help cut down on waste.
Tip: Always pick a material that fits the part’s job. This makes products strong, safe, and efficient.
Material Limitations
Every material has some limits in hpdc. Some common problems are porosity, cold shuts, and shrinkage defects. These problems can make parts weaker or less smooth. The table below lists some usual issues:
Defect Type | Description | Impact on Manufacturing |
|---|---|---|
Porosity | Small holes from trapped gas | Makes parts weaker |
Cold Shuts | Metal does not fill the mold completely | Causes weak spots |
Shrinkage Defects | Material changes size as it cools | Can lead to wrong part sizes |
Flash Formation | Extra material leaks out of the mold | Needs extra cleaning |
Surface Defects | Marks or rough spots on the part | May look bad or not work as needed |
Misruns | Metal does not fill the mold | Part is incomplete |
Die Erosion | Mold wears out over time | Lowers accuracy and raises costs |
Soldering | Metal sticks to the mold | Hard to remove parts |
MORELUX fixes these problems with special solutions. They use smart tools like simulation software and X-ray checks. Vision systems help find and fix problems early. Their team picks the best material for each job. They use aluminum for cars, zinc for electronics, and copper for plumbing. They also use recycled materials and save energy to help the planet.
The main materials used in hpdc die casting are aluminum, magnesium, and zinc. Each one has its own special benefits:
