Louis Metals produces and supplies Copper C11400 Bars and Rods in Houston, USA, for high-conductivity copper with improved machinability for customers. C11400 or Free-Machining Copper is best used for parts with complicated turning, threading, or milling. Louis Metals provides consistent metallurgical structure to facilitate ease of fabrication and machining.
Copper C11400 is copper alloy with high conductivity that has a low content of sulfur (about 0.02–0.04%) to enhance machinability. Its tensile strength is between 230–310 MPa, and its conductivity properties remain above 90% IACS. It is best used for screw machine and turning applications but not welding. It exhibits high corrosion resistance and works satisfactorily in ambient and mildly corrosive environments.

Copper C11400 Bars and Rods have good thermal conductivity but are not ideal for high-temperature applications. They are best used at temperatures up to 200°C to prevent softening and degradation.
Yes, Copper C11400 Bars and Rods are fully recyclable. The material retains its properties after recycling, making it an eco-friendly option for sustainable industrial use and reducing environmental impact.
Copper C11400 Bars and Rods are naturally resistant to corrosion in many environments. However, in harsh conditions such as marine or acidic environments, additional protective coatings may be recommended.
Copper C11400 Bars and Rods are utilized in machined pieces, plumbing fittings, fasteners, switch parts, and electrical terminals. Because of their machinability, they find applications in automatic lathes and CNC machines in industries from electrical to mechanical systems. The alloy is well suited for producing intricate parts with precise sizes and high productivity.
