Product Description

High Quality C21000 Copper Flat Bar

Precision-engineered for superior performance in industrial applications, this flat Copper Bar is manufactured from premium C21000 brass alloy (H96), offering an exceptional balance of excellent electrical conductivity, thermal conductivity, corrosion resistance, and mechanical workability. It is the ideal material for manufacturing electrical components, heat exchangers, decorative hardware, and various machined parts across diverse industries.

C21000, also known as commercial bronze or H96 brass, is a high-copper, low-zinc alloy (Cu: 94.0-96.0%, Zn: Remainder). Our C21000 Copper Flat Bar is a hot-rolled or cold-drawn solid flat profile, designed to meet strict ASTM, JIS, and GB standards. It combines the best characteristics of copper and zinc, providing higher strength and hardness than pure copper while retaining excellent ductility, making it highly suitable for bending, stamping, forging, and machining operations. This product is widely recognized for its reliability in electrical, electronic, plumbing, and mechanical applications.

Key Features

1. Excellent Electrical & Thermal Conductivity

High Quality C21000 Copper Bar for Industrial

With a high conductivity rating of ≥45% IACS, C21000 flat bar efficiently conducts electricity and heat, making it perfect for electrical terminals, connectors, bus bars, and heat sink applications. Its thermal performance ensures efficient heat dissipation.

2. Superior Corrosion Resistance

The alloy forms a protective, tarnish-resistant patina, offering robust resistance to atmospheric corrosion, freshwater, and many alkaline environments. This ensures long-term durability and low maintenance in industrial and marine settings.

3. Exceptional Ductility & Workability

C21000 is renowned for its superb malleability and ductility, especially in the soft (annealed) condition. It can be easily bent, formed, stamped, and deep-drawn without cracking, facilitating complex shaping and fabrication.

4. Good Machinability

It exhibits excellent machinability, allowing for smooth cutting, drilling, milling, and tapping. This results in high-quality surface finishes and efficient production rates for machined components.

5. High Strength & Toughness

Compared to pure Copper Material(C11000), C21000 provides enhanced tensile strength and hardness, offering better structural rigidity and wear resistance for load-bearing and structural applications.

6. Aesthetic Appeal & Solderability

Possesses a bright, attractive golden color ideal for architectural and decorative uses. Additionally, it has excellent soldering and brazing characteristics, ensuring strong, leak-proof joints.

Industrial Applications

Electrical & Electronics: Bus bars, electrical contacts, connectors, switch components, circuit parts.
Heat Exchange: Cooling fins, condenser plates, heat exchanger components.
Plumbing & Hardware: Valves, fittings, fasteners, ornamental hardware.
Mechanical Engineering: Gears, bearings, washers, springs, machined parts.
Automotive: Radiator parts, electrical components.
Architecture & Decoration: Interior trim, door hardware, decorative elements.
