304Cu stainless steel bright wire

What is 304Cu Stainless Steel Bright Wire?

304Cu stainless steel bright wire (also known as 1.4567) is an enhanced variant of standard stainless steel wire with increased copper content. While maintaining the core properties of standard 304 stainless steel bright wire, the additional copper content significantly improves its corrosion resistance and machinability. This specialized bright wire exhibits excellent cold formability and consistent performance in machining operations, making it an optimal choice for demanding applications.

Properties and Advantages of 304Cu Stainless Steel Bright Wire

The composition of this premium stainless steel bright wire includes 18% chromium and 8% nickel, with added copper for enhanced performance. Key benefits include:

• Superior ductility for cold heading operations
• Reduced work hardening for improved machining
• Exceptional corrosion resistance, especially in marine environments
• Excellent tensile strength for spring applications
• Temperature stability up to 500ºF when properly treated

Common applications for 304Cu stainless steel bright wire include:

• Precision fasteners
• Electrical components
• Chemical processing equipment
• High-performance machined parts
• Marine and seawater installations
• Spring manufacturing

For spring applications, this bright wire is typically supplied in cold-drawn condition. The nickel-coated variant offers enhanced lubrication properties, reducing friction during the coiling process and extending tool life.
