Howmet Aluminum Casting Ltd. Georgetown Casting is a manufacturer of
premium-quality, precision non-ferrous castings. The main alloy is aluminum
(A356); however, we also cast in copper-based alloys.
The alloys we pour include the following:

A combination of highly skilled people, the latest in robotics and ISO 9002
accreditation has helped us become a leading force in the industry. By
incorporation of various functional features into the casting configuration the
number of sub-assemblies may be reduced, thus lowering overall manufacturing
costs. We also offer complete-to-print capabilities, such as, machining, and
manufacturing, and finishing. In addition Rapid Proto-Typing technology is
available.
Howmet Aluminum Casting Ltd. Georgetown Casting has a wide range of product
capabilities. Castings included much small, relatively straightforward geometry
as well as a number of very intricate cored Pump Housings and complex Electronic
Boxes. The use of both shell and solid mold manufacturing helps facilitate this
wide part range. Alloys poured include aluminum and various copper base
compositions.
Howmet Aluminum Casting Ltd. Georgetown Casting sells primarily from within
based on performance, service and relationships developed over time.
