Brass and bronze sand casting is a popular technique for manufacturing different kinds of products and product components using brass and bronze alloys. These are highly durable, versatile metals that can be used for a wide range of applications and manufacturing productions.Brass is a metal alloy that contains zinc as principal alloying element while bronze is a combination of copper and tin. Although brass is principally zinc, it can likewise contain other alloys like lead, nickel, tin, and aluminum, just like bronze doesn’t always contain tin and other copper alloys like iron, lead, phosphorus, manganese, aluminum, and silicon.
Because of brass’ gold-like appearance and bright and shiny glow, it is widely used for decoration. However, it is also an excellent choice of material for low-friction applications like gears, locks, doorknobs, bearings, valves, and ammunition casing. Some brass casting service providers and manufacturers specialize in fabricating brass materials for electrical and plumbing applications. Others still, deal extensively in specialized uses like brass musical instruments such as bells and horns. Brass makes for a great choice of material for this particular class of instruments because of its rich and brilliant acoustic properties. Bronze on the other hand, are very widely used in cast metal sculpture creations. Bronze alloys have this unusual, but highly desirable property of slightly expanding before they completely set, allowing the metal to fill the finest details of a bronze sand casting or any other type of casting mold. As the alloy cools, however, it shrinks by a small degree, which makes the resulting product a lot easier to separate from its mold.
Brass and bronze alloys are valued for their workability, corrosion resistance, good electrical and heat conductivity, and flexibility in use. General requirements and standard specifications for bronze and brass casting mainly depend on the standards used and the specific production requirements, but forged brass and bronze materials typically have to go through a chemical bath to remove tarnish and oxidation.
