Bronze alloys are a great choice for casting purposes because they maintain their strength and durability throughout the process.

At Nifty Alloys, we offer several bronze casting alloys to meet your manufacturing and machinery needs.

Any casting application requires a ductile, resilient metal. The physical and chemical properties of bronze alloys allow them to consistently check these boxes. As a great heat conductor, these metals don’t become brittle when melted down, and they’re typically denser than steel. They also boast superior anti-corrosive benefits.

Our diverse selection of bronze casting alloys allows you to find the perfect material for your unique application.

Bronze Alloys

Metallurgists classify bronze alloys according to their composition. Here are some common alloys:

• Aluminum bronze: Aluminum bronze contains 6% to 12% aluminum, up to 6% iron, and up to 6% nickel. It is a strong alloy with excellent corrosion resistance and wear resistance. Aluminum bronze is the alloy of choice for pumps, valves, or other hardware exposed to corrosive fluids.
• Cupronickel: Cupronickel or copper nickel is a bronze alloy containing 2% to 30% nickel. The alloy displays high thermal stability and corrosion resistance, particularly in moist air or steam. It is also superior to other types of bronze in seawater. Uses of cupronickel include ship hulls, pumps, valves, electronics, and marine equipment.
• Nickel silver: Despite its common name, nickel silver doesn’t contain any silver. It gets its name for its silvery color. Nickel silver contains copper, nickel, and zinc. It is moderately strong and has decent corrosion resistance. Nickel silver finds use in musical instruments, optical equipment, decorations, and dinnerware.
• Phosphor bronze (tin bronze): Phosphor bronze contains 0.5% to 1.0% tin and 0.01% to 0.035% phosphorus. This alloy is tough and strong and has a fine grain, low coefficient of friction, and high fatigue resistance. Phosphor bronze finds use in springs, washer, electrical equipment, and bellows.
• Silicon bronze: Silicon bronze includes both red silicon brass as well as red silicon bronze. Red brass contains about 20% zinc and 6% silicon, while red bronze contains less zinc. Silicon bronze is low in lead and may contain manganese, tin, or iron. Silicon bronze has high corrosion resistance and strength. It is used for pumps and valve stems.
