Kasashin aluminium daga kasashin aiki sun babban fadi ci gaba mai tsarin aiki, resistance to heat, wannan kai. Aluminium alloys na cikakken da kai yanzu ake samun wannan temperatures da pressures na engine. Babu, wannan properties na lightweight suna yi adda daidai ga weight na vehicle don samun fuel economy da performance. Don haka, wannan kasashin suna so daidai ga efficient heat management ya kamata, kuma wanda suka sami wani sabon aiki vehicles. Machining na accurate baya ne daga nitto tolerances to internal passage configurations don samun efficiency. Kasashin aiki ya same da kawai don long time ga aluminium bane ya same rust. Wannan disadvantage ya ne wannan cost na higher compared to plastic intake manifolds.
