The material most of the work is done with.
{{SALTI}}Materials › Polyamide 66 (PA 66)
Stiff, heat- and oil-resistant: the usual choice for structural parts under the bonnet and inside machinery. What really changes from one grade to the next is how much glass fibre it carries — and it changes everything, not a little.
It must be dried before every moulding run, always. The figures below exclude specimens declared as conditioned, but on many datasheets the conditioning is not stated: they cannot therefore be read as dry-as-moulded values. In service, conditioned to ambient humidity, the stiffness of PA 66 drops noticeably — anyone dimensioning on datasheet figures without allowing for it errs on the dangerous side.
Tough — it bends before it breaks
Clips, hinges, pump bodies, parts that must absorb an impact.
The compromise used almost every time
Brackets, engine mounts, housings, structural parts under the bonnet.
When stiffness is all that matters
Load-bearing elements, arms, parts that replace aluminium.
Each row is the median of a selection of manufacturers’ datasheets held in our archive, with the property, the standard and the number of grades stated next to the value. These figures describe the sample: they serve to compare the levels with one another, not to size a part, and they are not a guaranteed material specification. For that you need the datasheet of the chosen grade, which we supply on request.
Where a level shows no value, the documented sample was not sufficient: we prefer to remove the figure rather than publish one that does not hold. HDT and impact strength are deliberately absent, because datasheets often do not state the test condition — whether HDT is at 1.8 or 0.45 MPa, whether the impact specimen is notched — and values collected under different conditions cannot be compared.
Parts that came out of our own machines: geometries that elsewhere would need moulds, finishes obtained in house.
