Pioneering Services

Heat Treated Parts

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 on Aluminum Alloys by Newton Heat Treating

Cold Stabilization

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

Aluminum Parts that have undergone thermal cycling

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.

Aluminum Parts that have been straightened


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.
