Compare all 5 conditionsHide

What is C36200?
C36200 is a leaded free-cutting brass in the C20000–C49999 family, close to C36000 in composition and use, with a tin content sometimes specified for added corrosion resistance. It machines at the benchmark 100 rating and provides 400 MPa tensile, 310 MPa yield, 25% elongation, 115 HB and 26% IACS, supplied mainly as drawn rod, hex and hollow bar for screw-machine production. Cold formability is poor (score 20), service is capped near 200 °C, and the lead prevents fusion welding. C36000 or C35600 are the nearest alternatives for the same machining behaviour. C36200 has a density of 8.5 g/cm³ (0.307 lb/in³), lighter than 65% of copper alloy grades. It melts at 885°C (1,625 °F). C36200 has a yield strength of 310 MPa (45 ksi) and a tensile strength of 400 MPa (58 ksi) — stronger than 64% of copper alloy grades. Elongation at break is 25% and the elastic modulus is 97 GPa (14.1 Msi).

Working with C36200
Is C36200 easy to machine?
Benchmark free-cutting alloy: use zero-to-negative rake tooling, high speeds, light coolant; chips break short and tool wear is minimal.
Can C36200 be welded?
Fusion welding is not recommended because of lead and zinc fume/hot cracking; join by soft soldering (excellent) or low-temperature silver brazing (fair).
Can C36200 be formed, bent or molded?
Hot forge/extrude at 650–750 °C readily; cold bending, staking and knurling only in O60/H01 and with generous radii — H02+ cracks easily.
C36200 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| Cufree-cutting brass range per CDA registration | 60 – 63 | 61.5 |
| Pbfree-machining addition | 2.5 – 3.7 | 3 |

What surface finishes work on C36200?
Polishes and buffs to a bright yellow finish; takes nickel/chrome and decorative plating well after proper lead-smut removal (acid dip) before electroplating.
Surface treatments FabDigit runs on copper alloy parts — pick them in the quote configurator or call them out on the drawing. Each links to its datasheet in the surface-finish library (thickness, specs, call-out, material verdicts).
How much does C36200 cost?
C36200 is a premium-cost copper alloy ($$$), cheaper than about 51% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.

What is the yield strength of C36200?
C36200 has a typical yield strength of 310 MPa (45 ksi) and a tensile strength of 400 MPa (58 ksi) — stronger than 64% of copper alloy grades. Strength varies by condition: see the 5 listed tempers.
Is C36200 easy to machine?
Yes — machinability is rated excellent (100/100, better than 100% of copper alloy grades). Benchmark free-cutting alloy: use zero-to-negative rake tooling, high speeds, light coolant; chips break short and tool wear is minimal.
Can C36200 be welded?
Not readily — weldability is rated poor (15/100). Fusion welding is not recommended because of lead and zinc fume/hot cracking; join by soft soldering (excellent) or low-temperature silver brazing (fair).
What surface finishes work on C36200?
Polishes and buffs to a bright yellow finish; takes nickel/chrome and decorative plating well after proper lead-smut removal (acid dip) before electroplating.
Can C36200 be formed, bent or molded?
Hot forge/extrude at 650–750 °C readily; cold bending, staking and knurling only in O60/H01 and with generous radii — H02+ cracks easily.
What is the maximum service temperature of C36200?
C36200 is rated for continuous use to about 200°C (392 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between C36200-H02 and C36200-O60?
H02 is the default condition — standard stock condition for screw-machine rod: best combination of strength, straightness and chip control. O60: softest condition; pick when some bending, staking or upsetting is needed after machining. Yield strength is 310 MPa in H02 versus 125 MPa in O60.
How much does C36200 cost?
C36200 is a premium-cost copper alloy ($$$), cheaper than about 51% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
