Description
🔩 High-Quality C36000 Brass Rod – Free-Cutting Bar for CNC Machining
🧱 Product Overview
The C36000 Brass Rod, also known as Free-Cutting Brass or 360 Brass, is one of the most widely used copper alloys due to its excellent machinability, moderate strength, corrosion resistance, and appealing golden color. This high-performance C36000 brass rod is composed primarily of copper and zinc, with a small addition of lead to improve its cutting characteristics. As such, it is a go-to material for precision machining, screw machine parts, fittings, valves, and electronic components.
At NiTiCu Metal, our C36000 brass rods are manufactured in compliance with ASTM B16 standards, ensuring dimensional accuracy, metallurgical consistency, and tight tolerance. Whether you are producing high-speed turned components or durable structural elements, our brass bars offer superior surface finish and machinability at high throughput.
🔍 Chemical Composition (ASTM B16 Standard)
| Element | Symbol | Typical Content (%) |
|---|---|---|
| Copper | Cu | 60.0 – 63.0 |
| Zinc | Zn | Balance |
| Lead | Pb | 2.5 – 3.7 |
| Iron | Fe | ≤ 0.35 |
The presence of lead in C36000 brass rod is the key factor enabling its free-cutting nature. Lead particles act as chip breakers and lubricants during cutting operations, which extends tool life and enhances surface finish.
