Global commercial heat treater HTA Group (HTA) ordered a vacuum aluminum brazing furnace. It will operate within a tight temperature tolerance of +/- 3° C, as dictated by AMS2750F, allowing HTA to continue to provide accredited heat treatment processing services to the global aerospace industry.
With three locations in Australia and one in the United States, HTA will be using this furnace to braze aluminum parts for applications where the use of brazing flux is not permitted due to corrosion. This is the seventh furnace -- and the 3rd vacuum brazing furnace -- that SECO/WARWICK will be providing to HTA.
"Our team of experienced heat treatment professionals appreciate working with SECO/WARWICK experts and technologies," said Norm Tucker, director at HTA Group. "We demand high quality, precision solutions due to the stringent requirements of the aerospace applications that we work with."
The vacuum aluminum brazing system has been designed with 6 temperature control zones in order to meet the temperature requirements of +/- 3° C as specified by the AMS2750F pyrometry specification. Additionally, the furnace provides the deep vacuum and perfect temperature uniformity to meet the Class 1 requirements of the pyrometry specification. The powerful high vacuum system will be equipped with a large diffusion pump and built to accommodate loads up to 800 x 800 x 1600mm (W x H x D). The furnace will be equipped with an external gas cooling system, which will both accelerate the process and improve the part quality after brazing.
