63/37 Yellow Brass
Product Description
Sunraj Industries exports 63/37 Brass which is also known as Common Brass and Yellow Brass. 63/37 Brasses are copper zinc alloys with a wide range of engineering uses. The addition of zinc to copper raises the strength and gives a range of properties, and the brasses are a very versatile range of materials. They are used for their strength, corrosion resistance, appearance and colour, and ease of working and joining. The single phase alpha brasses, containing up to about 37% zinc, are very ductile and easy to cold work, weld and braze. The dual phase alpha-beta brasses are usually hot worked. Brasses are resistant to corrosion in many media.
63/37 Brass is widely used in Radiator Tanks and Cores, Flashlight Shells, Lamp Fixtures, Fastenerslocks, Hinges, Pins, Rivets, Buttons, Plumbing Accessories.

70/30 Cartridge Brass
Product Description
Sunraj Industries exports 70/30 Brass Sheet, Strips and Foils which is also called Cartridge Brass, Spring Brass and Spinning Brass. 70/30 Brass have excellent ductility and strength, and are the most widely used brasses. These alloys have the distinctive bright yellow colour normally associated with brass. They have the optimum combination of strength and ductility in the copper zinc alloys, coupled with good corrosion resistance.
70/30 Brass is used for architecture, drawn and spun containers and shapes, electrical terminals and connectors, door handles, plumber’s hardware.
Typical Applications :
Architecture, grillwork, appliances, drawn & spun containers and components, radiator cores and tanks, electrical terminals, plugs and lamp fittings, locks, doors handles, name plates, plumbers hardware, fasteners, cartridge cases, cylinder liners for pumps.

Leaded Brass
Product Description
Sunraj Industries exports Leaded Brass also known as extra high leaded brass. Engraving brass and is traditionally used for machine engraved name plates due to its combination of high strength and free machining characteristics. Leaded Brass has good corrosion resistance to weathering and fair resistance to many waters. C35600 weathers to the warm brown bronze tone which is desirable for name plates.
Typical applications: Engraved name plates and plaques, appliance trim, clock components, builders hardware, gear meters, free machining sheet and plate.
