Magnesium alloys are a popular choice for steering wheels due to
their high strength-to-weight ratio, making them lightweight yet
durable. They also offer excellent damping properties, reducing
vibration and improving vehicle performance. Additionally,
magnesium alloys are known for their good castability and are often
used in high-pressure die casting for complex parts like steering
wheels. Here's a more detailed look:
Weight and Strength:
Magnesium alloys are significantly lighter than steel or aluminum,
which is a major advantage for reducing vehicle weight and
improving fuel economy. They also offer a good strength-to-weight
ratio, allowing them to withstand significant stress.
Damping Properties:
Magnesium wheels have damping properties that are far superior to
aluminum wheels, contributing to a smoother and more controlled
ride.
Castability:
Magnesium alloys are easily cast using high-pressure die casting, a
process well-suited for producing complex steering wheel designs.
Common Alloys:
MgAl5Mn and MgAl6Mn are commonly used magnesium alloys for steering
wheels due to their excellent elongation and impact strength.
Recycling:
While magnesium alloys can be recycled, the concave shape of
steering wheels and the strong adhesive properties of polyurethane
resins pose challenges in recycling. However, new methods are being
developed to address these issues.
It is worth noting that this magnesium alloy night vision device
adopts the unique semi-solid forming process of EMT, which has fast
forming speed and high precision, and is suitable for large-scale
production.
The principle of the semi-solid injection molding equipment for
magnesium alloys:
The magnesium alloy particle raw material enters the semi-solid
slurry preparation tube (material tube) by negative pressure and
gravity, and is hot melted in the material tube to form a
solid-liquid two-phase mixture (semi-solid slurry) under the action
of screw stirring and shearing. Due to the stirring and shearing,
the solid phase becomes spherical and the slurry has good fluidity.
In this state, the slurry is high-speed pressed into the mold for
molding, cooled and shaped, and the integrated magnesium alloy
product can be obtained.
About Us:
EMT Precision Manufacturing is a technology-based enterprise that
integrates research and development of high-precision thixomolding
technology for magnesium alloys, equipment manufacturing, and
magnesium alloy product manufacturing.
The core team is one of the first teams in China to be exposed to
thixomolding technology for magnesium alloys. Through more than ten
years of arduous research and development, they have mastered the
world's leading thixomolding core technology for magnesium alloys,
breaking foreign monopolies.
Significantly reducing the purchase and usage costs of thixomolding
equipment for magnesium alloys and the manufacturing costs of
magnesium alloy parts, breaking through the biggest bottleneck of
the widespread application of magnesium alloys.
