Brass, bronze and nickel silver are copper alloys that can be manufactured in many different forms. These brasses are the only common metal that possesses virtually every positive attribute from corrosion resistance to aesthetic beauty. Architects, designers and fabricators must decide which metal forming or casting process produces the right combination of attributes and cost-effectiveness.
Consider the wide range of forms available:
- Extruded rod, bar and shapes
- Hot stampings and forgings
- Rolled plate, sheet and strip
- Drawn or welded tube
- Castings (sand, shell, investment, gravity and pressure die
For many architectural applications, it is common to combine sheet, tubing and extruded profiles to assemble a door, elevator cab or stairway. Hardware manufacturers may want to match lock sets and door pulls with thresholds and kick plates and hinges. Each item may be produced from a different raw material form. Since color and texture drive the material decision to brass, determining the correct alloy when combining material forms is crucial.
