Alloy (UNS)	Key Alloying Element	Machinability (% of C36000)	Conductivity (% IACS)	Key Trade-off / Note
C14700	Sulfur (S)	90%	~95%	Best balance for most applications. Excellent conductivity with great machinability.
C14500	Tellurium (Te)	90%	~95%	Very similar to C14700. Tellurium offers slightly better tool life in some operations. Often called "Tellurium Copper."
C36000	Lead (Pb) & Zinc (Zn)	100% (Benchmark)	~26%	Free-Cutting Brass. Best machinability, but poor conductivity. Used where conductivity is NOT required.
C11000	None (ETP Copper)	20%	100%+	Pure copper. Worst machinability, best conductivity/formability. Used for wiring, busbars where no machining is needed.

 

 

 

 

• Electrical Components: Used in connectors, terminals, and bus bars due to its high conductivity and machinability.
• Heat Exchangers: Suitable for thermal management systems in HVAC and industrial equipment.
• Plumbing and Fittings: Commonly used in plumbing systems, valves, and fittings due to its corrosion resistance.
• Machined Parts: Ideal for producing precision-machined components in automotive, aerospace, and manufacturing industries.
• Fasteners and Hardware: Used for screws, bolts, and other hardware requiring high strength and corrosion resistance.

 

C14700 Copper Bar is the engineer's solution when you need to mass-produce a complex, precision part from copper that must also carry significant electrical current or dissipate heat. It sacrifices a negligible amount of conductivity to gain a massive improvement in manufacturability, reducing machining time, improving tool life, and lowering overall production costs for machined components. It is a classic example of a high-performance, specialized material designed for a specific set of industrial challenges.

 

C14700 Copper Bar is a versatile and reliable material that bridges the gap between high conductivity and ease of machining. Its unique combination of properties makes it an ideal choice for applications requiring precision, durability, and efficient electrical or thermal performance. Whether for electrical systems, thermal management, or machined components, C14700 delivers exceptional performance and value.
