Curtiss-Wright Surface TechnologiesCurtiss-Wright Surface Technologies applies engineered surface treatments and analytical testing to help critical components withstand fatigue, corrosion, heat and other harsh service conditions. Formed through the company’s “One Curtiss-Wright” initiative, it brings together more than 70 years of metal-improvement experience, including a laser-peening heritage that reaches back to aircraft wing skins formed in the early 1950s. Its global network spans more than 60 facilities in 16 countries and includes mobile laser-peening teams for large components and customer-site work.TWINSBURG, OH
Aalberts Surface TechnologiesBuilt from heat-treating businesses founded as early as 1962, Aalberts Surface Technologies transforms metal components through heat treatment, brazing, and hot isostatic pressing. The company has grown those operations into a network spanning seven states, with two side-by-side HIP presses in Greenville, South Carolina, and a proprietary NitroSteel® treatment developed as a longer-lasting alternative to chrome-plated bar. Its facilities support demanding aerospace work as well as automotive, agricultural, material-handling, and other industrial applications.WADSWORTH, OH
Surface Finish Technologies, IncFor more than 30 years, Elmira-based Surface Finish Technologies, Inc. has helped manufacturers protect and improve metal parts through plating, anodizing and other surface-finishing treatments. The company handles everything from very small components to parts up to 8 feet long and 500 pounds, with typical in-house turnaround of one to three days and rush service available. Its work is tracked through a computer-controlled quality system, with daily process-bath monitoring and corrosion testing available in-house.ELMIRA, NY
HI TecMetal Group IncSince 1943, HI TecMetal Group has handled precision brazing, heat treating, welding, and other thermal processing for demanding metal components from its specialized Northeast Ohio facilities. Formerly Technical Metal Processing, the company pairs decades of metallurgical experience with brazing engineering and production capabilities that span prototypes through high-volume work. Its HiTech Aero operation holds Nadcap accreditation for heat treating and brazing, as well as AS9100D with ISO 9001:2015.EASTLAKE, OH
