Update conducted a short interview with Jonathan
Weiler about his 2023 WCX
session, " Advances in Lightweight
Materials " (session code M109).
The 11-year SAE member is chief
engineer at Meridian Lightweight
Technologies and his Ph.D.
research at University of Western
Ontario was on the processstructure-property
relationship in
magnesium alloys.

What are the most interesting developments in
magnesium at the moment?
Magnesium has seen its greatest successes in the form
of high-pressure die-castings in the automotive industry.
Common applications include cross-car beams, transfer
case housings, seat frames, closure inners, and front-end
carriers, among many others. More recently, applications

in electric vehicles have been
increasing, including a novel
application in charger housings.
Medical applications are seeing
significant developments in
orthopedic use, such as screws
and implants, due to
magnesium's excellent
biocompatibility, allowing for
slow dissolution within the
body while the repaired bone
regains strength. Using
magnesium in this application
removes the necessity for a
secondary surgery to remove
the screws or implants.
Magnesium has seen a very
long history in aerospace
applications, including fuselage
and engine components. More
recently, magnesium sandcastings
have been used in
transmission and gearbox
housings in helicopters and
airplane applications.
What developments do you
foresee in the short term and
the long term?
Due to its density and strengthto-weight
ratio, magnesium has a
very promising potential in the
transportation industry, and due
to its biocompatibility and similar
stiffness with human bone
material, a very interesting
