Most business who are in need of a lightweight die casting component, which has an incredible strength to weight ratio, chose magnesium over other components. This is because of the excellent die casting properties of Magnesium. In fact, most of the die casters use the magnesium alloy AZ91D when they are casting magnesium.
AZ91D is a highly purified magnesium alloy that offers excellent corrosion resistance for the die casting magnesium parts. In addition to that, it also allows die casters to easily bring the desired shapes into the finished product without compromising on the quality. Below are a few more benefits of AZ91D that will explain why die casters die casters in Mexico love to work with the component.
- Extended tool life
- Easiest alloy for machining
- High electrical and thermal conductivity
- Excellent choice for complex parts
- Incredible vibration and noise dampening properties
- Offers exceptional RFI and EMI shielding
- Praiseworthy finishing characteristics
- Lightweight
- Scrap materials are 100 percent recyclable
Most of the die casting companies around the world use hot-chamber die casting process for producing die cast magnesium parts. In this particular die casting process, die casters submerge the metal injection parts into a reservoir of molten magnesium. Magnesium is then forced into the die with the help of a hydraulically powered piston. Besides, the excellent flow characteristics of magnesium enables die casters to easily produce complex shaped finished products.
Magnesium is approximately 75 percent less lighter than steel, yet it has no significant loss of strength. This makes magnesium a suitable component for net shape, thin-walled, and complex castings. In addition to that, it also offers incredible dimensional stability. Most die casters find it very difficult to meet with the desired tight tolerance when they are working with steel. However, they are easily able to bring all the desired effects to their finished products when they are working with magnesium.
Another major advantage of working with magnesium castings is that the tooling costs are less. This is because die casters in Mexico are able to consolidate multiple parts into a single component when they are die casting magnesium. This will also significantly reduce assembly and welding costs and boosts the rigidity of the component. In addition to that, magnesium is also stiffer and stronger than most advanced engineering plastics, which also makes it a suitable choice for die casting complex parts.
