Anucha Metals supplies Copper C11300 Bars and Rods, a free-machining copper alloy known for its excellent workability and moderate strength. It has enhanced machinability because of arsenic additions, which makes C11300 popular in applications that require both high conductivity and easy machining. Manufactured in Bangkok, Thailand, our C11300 bars and rods are produced according to ASTM B16 standards. With a bright finish and consistent dimensional tolerance, Anucha Metals provides C11300 in standard and custom lengths for use in connectors, fittings, plumbing, and electrical components that need easy machining and long service life.
C11300 consists of ~99.5% copper and ~0.5% arsenic. This composition improves machinability, making it easier to work with than pure copper grades. It provides tensile strength around 310 MPa, yield strength of ~90 MPa, and electrical conductivity of ~90% IACS. The alloy also resists softening at moderately elevated temperatures. Its corrosion resistance is good, and it can be brazed or soldered easily.

Copper C11300 Bars and Rods naturally resist corrosion due to their high purity and deoxidized composition. However, in harsh or aggressive environments, additional protective coatings may be applied for enhanced durability.
Yes, Copper C11300 Bars and Rods are fully recyclable. Copper maintains its properties after recycling, making it an eco-friendly material for reuse in various industrial applications.
Copper C11300 Bars and Rods can be used for potable water applications due to their corrosion resistance and non-toxic properties. However, local regulations should be checked for specific usage requirements.
C11300 bars and rods are used for electrical terminals, plumbing fittings, hardware components, and automotive electrical contacts. Its easy machining makes it suitable for screw machine parts, valves, switchgear, and connectors. In instrument manufacturing, it serves for sensor housings, threaded parts, and machined pins. In electrical distribution, it acts as bus bar connectors and switch parts. The alloy is valued in high-volume production settings where machining efficiency and electrical performance are both critical.
