[MW:1470] Re: radiography of aluminium

Hello Muhammed,
 
In response to your question below, X-ray radiography is you best choice due to quality issues. 
 
The second question is slightly difficult to answer as each tube/generator has different characteristics, as also the film and geometric variables have.  In referencing one of my resources, a higher end X-ray tube rated at 400-450 kV could theoretically penetrate thickness up to roughly 300 mm.  The lower limit for 50 kV is approximately 20 mm.
 
I usually work with castings from 30 mm to approximately 75 mm, although, I primarily use digital radiography using a CMOS detector. 
 
A generally accepted method of ensuring acceptability of a method is to demonstrate required sensitivity (i.e. hole-type or wire-type image quality indicators) per referencing code. 
 
I have a colleague that is better accquainted with thinner materials.  I will forward him your question and I will email you if I can clarify practical limits.

Thank you,

Charles Nelson

Hi friends,
 
Good morning,
 
I have a query regarding the radiography of aluminium.
 
X-ray or gamma ray is better for aluminium?
 
If x ray is better , what is the thickness range it can be done?
 
If gamma ray is better , what is the thickness range it can be done?
If anybody having the procedure, please forward

Thanks & Regards
Muhammed Ibrahim PK
