Extruded Magnesium Profiles Overview
Definition and Key Features
You see extruded magnesium profiles in many new products. These profiles are made by pushing magnesium alloys through a shaped die. This process makes bars, tubes, strips, and special shapes. They are very light, so they are good for things that need to be less heavy. Magnesium is the lightest structural metal. Its density is only 1.74 g/cm³. This helps in cars, planes, and electronics.
Extruded magnesium profiles are strong for their weight. They give support without making things heavy. Engineers pick magnesium alloys because they are strong, stiff, and resist rust. These profiles can work better than other metals in some uses. The extrusion process lets you make tricky shapes and change properties for your needs.
Tip: When you pick extruded magnesium profiles, you get many magnesium alloys. Each alloy has its own mechanical properties and chemical makeup. For example, Mg-1Zn-0.4Gd-0.2Ca-0.5Zr bends well at room temperature. Mg-3.0Al-0.5Mn-0.2Zn has a yield strength of 150 MPa and stretches over 12%. You can see more details in the table below:
| Alloy Composition | Key Characteristics |
|---|---|
| Mg-1Zn-0.4Gd-0.2Ca-0.5Zr | Exceptional stretch formability at room temperature, Erichsen index > 7 mm |
| Mg-3.0Al-0.5Mn-0.2Zn | Yield strength of 150 MPa, elongation > 12% at room temperature |
| Mg-2.0–8.0Bi-0.5–6.5Al | Ultimate tensile strength of 280–320 MPa, elongation of 15–18% |
| Mg-0.8Ca-0.4Zn-0.1Sr-0.4Gd-0.5Zr | Yield strength > 250 MPa, corrosion rate < 1 mm/year in 3.5% NaCl solution |
The extrusion process lets you control the mechanical properties. You can change the alloy mix and how you make it. This helps you get the strength, stretch, and rust resistance you want. This makes extruded magnesium profiles a smart pick for tough projects.
Common Forms and EN Standards
You can find extruded magnesium profiles in many shapes. Companies make bars, rods, tubes, strips, channels, and special shapes. You can pick the shape that fits your project. The extrusion process helps make profiles with exact sizes and good quality.
You need to follow industry standards when picking extruded magnesium profiles. The European Norm (EN) standards give rules for magnesium alloys and their products. These rules make sure you get profiles with good mechanical properties, chemical makeup, and surface finish. For example, EN 1759 gives rules for magnesium and magnesium alloy extruded products used in building things.
Note: Good suppliers like mijimg.com follow EN standards and give you technical data for their extruded magnesium profiles. You can trust their products to meet industry rules and work well.
EN standards help you get safe and good quality profiles. You do not have to worry about bad material or rough surfaces. If you pick profiles that follow EN standards, your project will meet the rules and work as planned.
You also find extruded magnesium profiles in semi-finished forms. You can cut, weld, or put these profiles together to make finished products. This means you can use them in car frames, airplane parts, medical tools, and electronic cases.
Comparison with Other Metals
You often look at extruded magnesium profiles next to other metals like aluminum and steel. Magnesium has some benefits that make it a good choice. Magnesium is 35% lighter than aluminum. This helps you make your products lighter. Sometimes, magnesium alloys are up to 20% stronger than aluminum.
The table below shows the main differences between extruded magnesium profiles and extruded aluminum profiles:
| Property | Magnesium | Aluminum |
|---|---|---|
| Weight | 35% lighter than aluminum | Heavier than magnesium |
| Strength | 20% stronger than aluminum | Higher overall strength |
| Ductility | Lower ductility | Better ductility |
| Formability | More challenging to form | Easier to form into shapes |
| Strength-to-weight ratio | Better performance | Lower performance |
You get a better strength-to-weight ratio with magnesium. This means you can build lighter things without losing strength. But magnesium is less bendy and harder to shape than aluminum. You need special extrusion methods to make hard shapes.
You also check things like tensile strength, stretch, yield strength, stiffness, and how well it handles hits. These things change with the alloy and how you make it. For example, the extruded AZ31B magnesium alloy acts differently in different directions. It is strongest in the extruded direction, but stretches less because of how it slips. In double directions, it is not as strong but stretches more because it slips easier.
- Tensile strength changes with alloy and how you make it.
- Stretch is different for cast and wrought magnesium alloys.
- Yield strength depends on the extrusion direction.
- Stiffness tells you how hard it is to bend.
- How well it handles hits changes with temperature.
You need to think about these things when you pick extruded magnesium profiles for your project. Magnesium saves weight and is strong, but it is harder to shape and less bendy. You can ask good sources like mijimg.com for help and quality checks.
Callout: When you use extruded magnesium profiles, you can make lighter products. These products are easier to move and put together. You can also save fuel in cars and use less energy in planes.
Magnesium alloys and the extrusion process give you special properties. You can change profiles to fit what you need, like high strength, rust resistance, or exact sizes. You learn a lot by knowing how magnesium is different from other metals.
Magnesium Extrusion Process
How Extrusion Shapes Magnesium Profiles
You make magnesium profiles with magnesium extrusion. This process pushes hot magnesium alloy through a die. It forms bars, tubes, or special shapes. You control heat and pressure for good results. Each alloy needs its own settings. Mg-Al alloys need higher heat. Mg-Zn-RE alloys use lower heat to keep their special features.
| Alloy Type | Temperature Range (°C) | Notes |
|---|---|---|
| Mg-Al alloys | 350–400 | Commonly extruded at higher temperatures. |
| Mg-Zn-RE alloys | 230–280 | Lower temperatures to retain quasicrystal dispersions. |
Magnesium extrusion needs careful control. The right heat makes strong and smooth profiles. The process changes the grain inside the metal. Using the right speed and ratio can make grains bigger or smaller. This changes how strong and bendy your profiles are.
Tip: Magnesium extrusion can make profiles stronger and more bendy. It does this by making a special grain structure called bimodal grain structure.
Quality and Precision Factors
You want magnesium extrusion profiles to fit your project well. Quality checks help you get the right size and shape. You measure length, width, and wall thickness. You also check the diameter and hole position. These checks make sure profiles work in assembly.
