Brass and Metal Parts
General Dynamics Ordnance and Tactical Systems – Canada is one of only a few producers of large-caliber brass cartridge cases in North America, GD-OTS Canada not only meets its own needs for quality components but also supplies all-caliber brass cases, propelling charges, projectiles, primers, fuses and many other components to munitions manufacturers and contractors around the world.
GD-OTS Canada operates a metal parts manufacturing plant In St-Augustin, near Quebec City. The facility produces a wide variety of brass cartridge cases for small, medium and large-calibre ammunition, in addition to metal components for projectiles and primers. It further offers CNC (computerized numerical controls) machining capabilities for specialty products.
Key areas of metal-working expertise include:
- Cold forming
- Cold drawing
- Heat treatment
- Chemical treatment
- Machining
- Metallurgical analysis


Brass components produced at the St-Augustin plant are made of different alloys. The yellow brass (copper alloy 260) contains approximately 70% copper and 30% zinc. It is used in the production of all types of cartridge cases and primer components. The red brass (copper alloy 220), which contains 90% copper and 10% zinc, is used mainly to manufacture small-calibre projectile jackets.
These alloys are cold formed and heat treated to minimize residual stresses and obtain the strength and elasticity required for the proper functioning of ammunition during the firing process. GD-OTS Canada purchases its raw materials in coils, strips, cups and discs at the most competitive market prices.
Producing cartridge cases on cutting-edge equipment, the plant also supports its operations with in-house state-of-the-art laboratories.
