Key Usage & Industrial Applications

At ICAST ALLOYS LLP, the investment casting process is used to create complex, thin-walled geometries that are difficult to achieve through traditional sand casting or machining. This process involves creating a wax pattern, coating it in a ceramic shell, melting the wax out, and pouring molten brass or bronze into the resulting cavity

01.Common Grades

Aluminum Bronze (C952, C954, C958)

Phosphor Bronze (PB1, PB2)

Silicon Bronze (C873, C875)

Tin Bronze / Gunmetal (C905, C907)

Yellow Brass (C85700)

High Tensile Brass (Manganese Bronze - C862, C863)

Leaded Brass

02. Key Characteristics

Aluminum Bronze (C952, C954, C958): Known for exceptional strength and resistance to oxidation; ideal for heavy-duty hardware

Phosphor Bronze (PB1, PB2): Features excellent wear resistance and low friction; used frequently for springs and bearings

Silicon Bronze (C873, C875): Offers high fluidity during casting and superior corrosion resistance in marine environments

Tin Bronze / Gunmetal (C905, C907): A classic choice for pressure-tight applications like valves and pumps

Yellow Brass (C85700): General-purpose engineering brass with high ductility

High Tensile Brass (Manganese Bronze - C862, C863): Combines the workability of brass with the strength of steel

Leaded Brass: Optimized for parts requiring extensive post-cast machining.

03.Pros

Corrosion Resistance: Unlike ferrous metals, these alloys do not rust, making them perfect for outdoor and underwater use

Dimensional Precision: ICAST achieves tolerances as tight as ± 0.005 inches per linear inch, reducing the need for expensive secondary machining

Surface Finish: Typically achieves a finish of 125–175 RMS, providing an aesthetically pleasing look for decorative and functional parts alike

Anti-Microbial & Non-Sparking: Brass is naturally antibacterial, and both alloys are safe for use in explosive environments

04.Cons

Material Cost: Copper-based alloys are generally more expensive than carbon steel or aluminum

Temperature Limits: These alloys have lower melting points compared to steel, making them unsuitable for extremely high-heat applications

Tarnishing: Without a protective coating or plating (which ICAST provides in-house), brass and bronze will develop a patina over time.
