70/30 brass, also known as cartridge brass, is one of the most widely used copper-zinc alloys in the world. Composed of 70% copper and 30% zinc, this alloy offers an exceptional combination of strength, ductility, and corrosion resistance. Whether you are looking for 70/30 brass case cups, brass strips, or brass coils, understanding their properties and applications can help you make informed purchasing decisions.
In this blog, we will explore everything about 70/30 brass case cups, brass strips and coils, their manufacturing process, key applications, and why they are the preferred choice across multiple industries.
Brass case cups are cylindrical or cup-shaped components made from 70/30 brass sheet or strip material. They are primarily used in the ammunition and defense industry as the base for cartridge cases. The deep-drawing capability of cartridge brass makes it ideal for forming these cups without cracking or splitting.
The 70/30 brass alloy is specifically chosen for case cups because of its:
These properties make 70/30 brass case cups a critical component in ammunition manufacturing, hydraulic fittings, and precision engineering applications.
Brass strips and coils are flat-rolled products made from 70/30 brass alloy. They are manufactured in various thicknesses, widths, and tempers to meet the specific requirements of different industries.
70/30 brass strips are typically supplied in:
Brass coils are the same material wound into rolls for easy handling, storage, and feeding into automated stamping or forming machines. They are widely used in high-volume production environments where continuous feeding of material is required.
The versatility of 70/30 brass strips and coils makes them suitable for a wide range of industries:
When compared to other copper-zinc alloys, 70/30 brass stands out for several reasons:
These advantages make 70/30 brass the top choice for manufacturers requiring precision, reliability, and performance.

Q1. What is 70/30 brass used for?
70/30 brass is used in ammunition manufacturing, electrical components, plumbing fittings, automotive parts, and decorative applications due to its excellent ductility, strength, and corrosion resistance.
Q2. What is the difference between 70/30 and 60/40 brass?
70/30 brass contains more copper, making it more ductile and corrosion-resistant than 60/40 brass. It is preferred for deep-drawing applications like cartridge case cups, while 60/40 brass is better for machining.
Q3. What are brass case cups used for?
Brass case cups are primarily used in the ammunition industry as blanks for forming cartridge cases. They are also used in hydraulic fittings and precision engineering components.
Q4. What tempers are available in 70/30 brass strips?
70/30 brass strips are available in soft, quarter-hard, half-hard, hard, and spring temper, depending on the forming and strength requirements of the application.
Q5. Where can I buy 70/30 brass strips and coils in India?
You can purchase high-quality 70/30 brass strips and coils from Rashtriya Metal, a leading supplier of non-ferrous metals offering competitive pricing, custom sizes, and pan-India delivery.
