Brass casting alloy is widely used in domestic and industrial applications because of its strength, stability, and clean finish. Calmet also provides a complete range of brass casting supplies to support diverse product requirements across sectors. Its warm golden colour, which can be polished to a bright shine, makes it a preferred choice for decorative and architectural use.
The material’s strong corrosion resistance allows it to perform well in marine environments, water systems, and outdoor structures. Its easy machinability supports the creation of accurate, smooth, and precise parts, while its good electrical conductivity makes it suitable for electrical fittings and related components.
Sand casting is a traditional and widely used method for producing brass components. In this process, a mold is formed by compacting sand around a pattern of the desired part. Molten brass is poured into the cavity created by the pattern. After solidification, the sand mold is broken to reveal the casting. Sand casting is prized for its cost-effectiveness and ability to form complex shapes with minimal tooling. It also delivers reliable results across a range of batch sizes and remains a highly versatile choice for many parts. Our foundry pairs this method with other options to meet precise needs and provide full brass casting services.
We select the proper molding method based on part geometry, finish needs, and production volume. This ensures consistent quality and tailored results for every requirement.
These flexible molding choices strengthen our ability to deliver reliable output as a brass casting company.
Investment casting, or lost-wax casting, is used to produce intricate, high-accuracy brass parts. We create a wax pattern, coat it with a ceramic shell, melt out the wax, and pour molten brass into the cavity. Once solid, we break the shell to retrieve a finely finished part. This method suits complex geometries and tight tolerances. For specialized runs, we apply Colloidal Silica, Micro investment, or Vacuum Assisted investment processes to match size, detail, and production volume needs. Our capabilities include work aligned with a full-service bronze casting foundry.
Die casting injects molten brass into steel molds under high pressure to form parts quickly and accurately. The process includes mold making, preheating, high-pressure injection, rapid solidification, and extraction of the finished part. Die casting offers high production rates, tight dimensional accuracy, and superior surface finish. While tooling costs are higher, the method is ideal for repeatable production of small-to-medium parts. For programs requiring high volume with close tolerances, die casting brass delivers consistent precision and high throughput.

Alpha Brasses contain 67–72% copper and 28–33% zinc. These alloys form a substitutional solid solution of zinc in copper and have a single-phase, face-centered cubic crystal structure. They offer a rich golden tone and are malleable, making them suitable for pressing, forging, and similar applications. Although robust, they can be relatively difficult to machine. The best formability is achieved at around 32% zinc, and their corrosion resistance allows them to be used in cold-worked conditions.
Alpha-Beta Brasses, also called duplex brasses, contain 55–65% copper and 35–45% zinc. They include both α and β’ phases, with the β’ phase having an ordered body-centered cubic structure with zinc atoms at the cube centres. This phase is tougher and stronger than α. These alloys are suitable for hot working, and those with higher zinc content appear brighter than alpha brasses. Strength peaks at approximately 45% zinc.
Beta Brasses consist of 50–55% copper and 45–50% zinc. Known for their hardness and strength, they are ideal for casting applications. Due to their high zinc–low copper ratio, beta brasses are among the brightest and least golden types. They are commonly used in higher-strength applications such as valves, gears, and bearings. These alloys can only be worked hot.
Gamma Brasses contain 33–39% copper and 61–67% zinc. Variants also exist in Ag-Zn and Au-Zn compositions, with silver ranging from 30–50% and gold around 41%. The gamma phase forms an intermetallic compound (Cu₅Zn₈) with a cubic lattice structure. Gamma brasses are typically chosen for specialized uses, including high-strength electrical contacts and fasteners.
