ALUMINUM SOLUTIONS
TAKES THE HEAT
Ideal or harsh environments, aluminum die castings are lightweight, yetwithstand the highest operating temperatures o all the die cast alloys.Its strength, rigidity, corrosive resistance and heat dissipating propertiesoer signifcant advantages to mechanical designers. Fully recyclablealuminum die cast alloys are secondary alloys 100% derived rom primaryaluminum scrap, an environmental advantage over primary aluminumalloys or machining, which have to be mined and extracted rom ore.

Telecommunications
& ComputingIn telecoms and computing
they are used in a broad
range o networking and
inrastructure equipment,
most importantly RF ilter
boxes and various housings
into which heat sinks are
oten designed as an integral
component.
Handheld Devices
In handheld devices, aluminum
die cast shields and housings
give EMI shielding, rigidity
and durability with minimal
additional weight. This is most
important in electronic
equipment where emission
and intererence suppressionrequirements are high.
Automotive
Aluminum die castings invehicles signiicantly
contribute to the weight-
saving requirements needed
to improve uel economy.
Our strength in automotive
is in electronic applications,
such as shields or telematic
equipment and housings
or sensors, where customers
are looking or proven quality
along with part-to-part
consistency over high volume.
In saety-critical occupant
restraint systems, Dynacast is
a leading supplier o airbag
housings and retractor spools.
Connectors
Dynacast aluminum diecastings are undamental to
the manuacture o heavy-
duty electronic connectors,
where complex housings give
excellent electrical perormance
and shielding properties,
especially in high-temperature
environments.
