Data sheets of aluminium alloys

We made out data sheets about the most common alloy aluminium castings, in five groups below :

We can make castings from every kind of alloys, but if you want from the most various other alloys.

Characteristics  (back)

ENAC-43000ENAC AlSi10Mg /a/ It can be tempered, Al-Si alloy with very good foundry work technician’s quality. After annealing it can achieve good rigidity rate. The addoptation takes place where the requirement is good corrosion stagnant. Well workable.
ENAC-42000ENAC AlSi7Mg This alloy – according to its good foundry work technician’s quality – is suitable for sand and chill casting. It’s corrosion stagnant is good. With annealing you can achieve good rigidity rate. Well machinable. It makes head of dynamic debit, it is pressure resist, good rigidity and persistent.
ENAC-46000ENAC AlSi9Cu3 /Fe/ It is elaborate, slim glut but it is limited corrosion stagnant alloy. It’s aging resist is harmonic with Si content. It’s balance quality affects the warm.
ENAC-44100ENAC AlSi12 /b/ Mainly for slim glut and elaborate chill alloy. Here is very good the fluidity quality, excellent form complete ability. It isn’t liable for chop.Vibration and pressure resist alloy with favourable corrosion stagnant.
