Key Features :

• High machinability, due to lead content, allows for easier and faster production.
• Good corrosion resistance, especially in mild environments like freshwater and mildly acidic conditions.
• Moderate strength that balances toughness and ductility, ideal for parts that require both durability and flexibility.
• Good formability, making it perfect for cold working operations like bending and drawing.
• Cost-effective, offering a great balance between performance and price when compared to more expensive alloys.
