Pioneering Services


Heat Treating

Newton Heat Treating is a leading aluminum heat treatment expert serving customers nationwide. We have four primary methods of quenching from air furnaces - glycol, cold water, hot water, and spray.


Cold Stabilization

Cold stabilization is a cyclic thermal shock process which is used to reduce the detrimental effects of residual stresses on aluminum alloys


Thermal Cycling

Thermal cycling is a controlled process of cycling through two temperature extremes at controlled rates. Parts and components that are used in space applications are often treated through this process.



During heating and quenching, a lot of mechanical deformation and stresses manifest on the parts, which often warp beyond acceptable tolerances. So, straightening services are necessary to bring the parts back within acceptable ranges.
