|HI TecMetal Group is headquartered in Cleveland Ohio. We offer 100+ metal technologies and services to a diversified customer base. Major markets serviced include automotive, aerospace, hydraulics and industrial OEM. Examples of services offered include brazing, heat treating, welding, and machining. HI TecMetal Group also offers value-added services such as a state of the art Materials laboratory and design engineering support.
HTG manufacturing processes allow the brazing of dissimilar metals with very thin thicknesses or thick to thin materials. Brazed structures offer excellent strength and fatigue resistance. Details are tack-welded or spot-welded together and then brazed. This technique eliminates the need for costly tooling normally required in more conventional joining methods.
We produce brazed honeycomb components from stainless steel and titanium alloys, as well as, nickel-based super alloys. Structures and parts can be made in various configurations, sizes and shape. The structures can be tailored to our customers design requirements. This technology allows excellent design flexibility. The weight and strength requirements can be exactly tailored to our customer's needs.
HTG offers quality service in the heat treating and brazing of metals. In the specialized field of furnace brazing, we offer the following services for commercial, aerospace and military applications:
Furnace brazing in accordance with MIL-B-7883 Type II and other widely recognized and accepted procedures.
Protective atmospheres including pure dry hydrogen, argon, nitrogen, helium or vacuum to eliminate oxidation or other contaminants, and ensure optimal wetting, brightness and joint quality of the finished assemblies.
Brazing of stainless and carbon steels; nickel alloys such as Monel 400, Inconel 600, and Hastelloys; lead-free brasses; OFHC copper; beryllium-copper and other base metals.
Active alloy vacuum brazing of tantalum, titanium, etc.
Filler metals including a variety of gold, silver, copper, and nickel-based alloys.
Fluxless brazing for high-vacuum applications.
We excel at difficult and complex assemblies of OFHC copper, stainless and Monel or other components which must be assembled by step-brazing using multiple filler metals. HTG's diverse manufacturing capabilities are enhanced by having a strong engineering group on staff to participate in design and build and simultaneous engineering programs.
HTG's engineers are equipped with the latest design tools CAD/CAM. These activities are supported by research and development programs which are on-going at HTG. Whether the requirements are customer specifications or re-design for product improvement, HTG has the design experience and resources.
