Re: Aluminium Heat Treatment and Times
Mr Schmitt,
Several different books by Alfred Spraul are listed with multiple copies each on ABEBooks. The first 30 (of 38) are listed from about $5 to about $25 plus postage. Just search at https://www.abebooks.com/
I couldn't find the Otto book listed there.
Enjoy!
Frank.
