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.
