[TheForge] spring temper for brass question

Wed Mar 10 21:38:00 2004

Hardening and tempering apply to many metals.  For example, aluminum can 
be work hardened, but can also be hardened by heating at an elevated 
temperature, natural aging and artificial aging.   One of the most 
common grades for structural work( and what I am building a plane our 
of) is 6061 T6, with the T6 indicating that it is hardened by soaking at 
at 900 degrees and then artificially aged by soaking at 350 degrees as I 
recall.  Brass is work hardened, but can be tempered by precise heat 
treatment as well is my understanding.    I would suggest that the 
original poster look to one of the clock making lists to get his 
question answered.  There are many brass springs found in clocks and 
tempering them is a normal process.
