Businesses in Jeddah, Saudi Arabia, seeking high-performance materials will find CU ZN 30 to be a critical component in their supply chain. Maiyam Group is committed to providing the high-quality copper and zinc necessary to produce alloys that meet stringent international standards, ensuring reliability and excellence for our clients in 2026 and beyond.

What is CU ZN 30 Alloy?

CU ZN 30 alloy is a specific type of brass characterized by its approximate composition of 70% copper (Cu) and 30% zinc (Zn). This particular ratio grants the alloy a unique set of properties that distinguish it from other brasses. It is often referred to as ‘cartridge brass’ due to its extensive use in manufacturing ammunition casings, where its high ductility and tensile strength are paramount. The alloy exhibits excellent resistance to corrosion, particularly stress corrosion cracking, and maintains good formability even after cold working. Its warm, golden appearance also lends itself to decorative applications where durability is also required. For manufacturers in Jeddah, Saudi Arabia, understanding the precise composition and resulting properties of CU ZN 30 is key to optimizing their production processes and ensuring the quality of their final products. Maiyam Group, through its supply of high-grade copper and zinc, supports the creation of such specialized alloys, adhering to certified quality assurance protocols by 2026.

The Properties of 70/30 Brass

The 70% copper and 30% zinc composition of CU ZN 30 alloy results in a material with:

• High Ductility: This allows the alloy to be easily formed into complex shapes without fracturing, ideal for deep drawing.
• Excellent Formability: It can undergo significant cold working and deformation processes.
• Good Tensile Strength: Provides the necessary strength for applications like ammunition casings and flexible conduits.
• Superior Corrosion Resistance: Particularly resistant to seawater and many industrial chemicals, making it suitable for marine and harsh environments.
• Good Solderability and Brazing Characteristics: Easily joined using common metal joining techniques.
• Attractive Appearance: Possesses a distinct yellowish-gold color.

These properties make CU ZN 30 a preferred choice for applications demanding reliability and performance, areas of significant focus for industrial development in Jeddah and Saudi Arabia.

Distinguishing CU ZN 30 from Other Brass Alloys

While all brasses contain copper and zinc, the ratio significantly impacts their characteristics. CU ZN 30 stands out due to its high copper content. For comparison:

• Red Brass (e.g., 85/15 Cu/Zn): Higher copper content leads to even greater corrosion resistance but less strength and ductility than 70/30 brass.
• Muntz Metal (e.g., 60/40 Cu/Zn): Higher zinc content increases strength and hardness but reduces ductility and corrosion resistance compared to 70/30 brass.
• Leaded Brass (e.g., 60/3.5/36.5 Cu/Pb/Zn): Addition of lead improves machinability but can compromise ductility and corrosion resistance.

Maiyam Group understands the importance of precise elemental composition. By supplying high-purity copper and zinc, we enable manufacturers to produce CU ZN 30 alloy that consistently meets the exact specifications required for specialized applications, ensuring top performance for industries in Jeddah through 2026.
