Howmet continues conversions with titanium component for M777 Howitzer.
With multiple conversions to investment castings, the M777 is the only artillery unit that uses titanium as a major structural material. Currently the U.S. Marine Corp is targeting 2005 as when the newly constructed M777 will be used as field artillery. BAE Systems, Barrow-in-Furness, England, is manufacturing the unit. Although none are on the line yet, Howmet stays prepared as other M777 fabricated parts could also be converted to investment castings in the future.
By converting production to investment casting, past components have exhibited a 50% decrease in welding time, increased high-stress properties and reduced distortion. Designers see this as a viable production route and more components can be developed using this method. Castings also allow the artillery unit to be lighter in weight.
