Brass

Free Machining Brass

Copper is alloyed with zinc to create brass. It's tough but simple to shape, stamp, or draw, making it a popular choice for a wide range of applications. Different levels of resistance to corrosion, ductility, and machining compatibility may all be achieved by altering the zinc concentration.

Forging Brass

Forging Brass is a copper-zinc alloy with qualities that may be changed to obtain different mechanical properties. It's a substitution alloy, which means that atoms from the two ingredients can swap places inside the same crystalline structure. Brass may be easily shaped when forged. Brass forging has high heat conductivity and excellent hot forgeability. They can be obtained in rod form.

Naval Brass

Naval brass is a high-strength, corrosion-resistant alloy composed of 60% copper, 0.75% tin, and 39.2% zinc. Naval brass has a great resistance to dezincification because of the presence of tin. It's commonly used in maritime construction when a tough, corrosive-resistant, and hard material is needed, and it may be utilised in both fresh and salt water. The strength and stiffness of naval brass are excellent. The alloys are known for their wear, fatigue, and tension corrosion cracking resistance.

Leaded Brass

Lead makes brass more machinable while also increasing its strength and corrosion resistance. Lead also aids in the closure of shrinkage holes, guaranteeing pressure tightness. Brass can contain up to 3.5 percent lead and is classified as low, medium, or high-leaded depending on the quantity. Leaded brass is used to make screws, valves, fittings, bearings, specialised fasteners, architectural hardware, and general-purpose machine components.

Lead Free Brass

Lead-free brass offers strong corrosion resistance, moderate strength, and ductility in some forms. It has powerful heated forms. Muntz metal is another name for it. The Cu/Zn ratios of 60/40, 63/37, 65/35, and 70/30 are the most common. Blanking, riveting, bending, hot forging, and pressing are all possible with ductile alloys.
