Working with C36000-H01

Is C36000 easy to machine?

The industry machinability benchmark — run high speeds with 0° or negative rake, sharp carbide/HSS, light oil or straight coolant; chips break into short crumbs and tool life is exceptional.

Can C36000 be welded?

Fusion welding is not recommended (lead cracking, zinc fume); join by soft soldering or silver brazing with adequate ventilation.

Can C36000 be formed, bent or molded?

Hot forge/extrude at 650–750 °C with excellent flow; cold bending, staking and roll-forming are poor because of the leaded α+β structure.

What surface finishes work on C36000?

Takes bright buffing, nickel/chrome plating and clear lacquer well; pickle or deburr to remove smeared lead before plating, and stress-relieve (~275 °C) to avoid season cracking.

C36000-H01 — frequently asked

What is C36000-H01 used for?

C36000-H01 is typically used for CNC turned threaded parts and fasteners, hydraulic and pneumatic fittings, valve stems and valve cores, plumbing adapters and manifolds, hex nuts and threaded inserts and gas and water meter bodies. In short: fastest machining brass.

What is the yield strength of C36000-H01?

C36000-H01 has a typical yield strength of 250 MPa (36.3 ksi) and a tensile strength of 360 MPa (52.2 ksi) — stronger than 54% of copper alloy grades. Strength varies by condition: see the 5 listed tempers.

Is C36000-H01 easy to machine?

Yes — machinability is rated excellent (98/100, better than 100% of copper alloy grades). The industry machinability benchmark — run high speeds with 0° or negative rake, sharp carbide/HSS, light oil or straight coolant; chips break into short crumbs and tool life is exceptional.

Can C36000-H01 be welded?

Not readily — weldability is rated poor (20/100). Fusion welding is not recommended (lead cracking, zinc fume); join by soft soldering or silver brazing with adequate ventilation.

What surface finishes work on C36000-H01?

Takes bright buffing, nickel/chrome plating and clear lacquer well; pickle or deburr to remove smeared lead before plating, and stress-relieve (~275 °C) to avoid season cracking.

Can C36000-H01 be formed, bent or molded?

Hot forge/extrude at 650–750 °C with excellent flow; cold bending, staking and roll-forming are poor because of the leaded α+β structure.

What is the maximum service temperature of C36000-H01?

C36000-H01 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 C36000-H02 and C36000-M30?

H02 is the default condition — default screw-machine stock: best combination of straightness, tolerance, chip breaking and strength. M30: large-diameter rod/hex as extruded; softest commercial condition, best for subsequent hot forging. Yield strength is 310 MPa in H02 versus 125 MPa in M30.
