Newton Heat Treating Co

Newton Heat Treating is a heat treating company that works on aluminum. It was founded in 1968. It serves the aerospace, automotive and commercial industries. The website says it has done aerospace work for over 40 years. It serves customers across the United States.

Heat treating means heating and cooling metal in a set way to change its strength. Newton works on every type of aluminum alloy and form. Parts range from small rivets to large forgings and castings. The company works to each customer's exact specifications.

The company holds NADCAP and ISO 9001/AS9100 certification. NADCAP is an audit program for special processes in aerospace. AS9100 is a quality standard for the aerospace industry. The company says these certificates help show that parts are processed to a consistent level and delivered on time.

Quenching is one core process. This is the fast cooling step after heating. Newton has four main quench methods from its air furnaces. These are glycol, cold water, hot water and spray. It was one of the first heat treaters to use polymer quenching and moved it from tests to full production on all its air furnaces.

The company also uses cold stabilization and uphill quenching. Cold stabilization is a cyclic thermal shock process. It reduces the harm from residual stresses in aluminum. Residual stresses are forces left inside a part. Newton uses X-ray diffraction to control the process. The company says this helps limit movement of the metal during machining.

Thermal cycling is another service. It moves parts between two temperature extremes at set rates. Parts for space uses are often treated this way. Straightening is also offered, because parts can warp during heating and quenching. The shop brings them back within accepted limits.

The site says the company runs an open reporting culture and keeps improving its quality system. Greg leads the business and has done so for over 25 years, honoring his father's legacy. The website lists the processes and certifications for engineers who need aluminum heat treating.
