Working with C36500-H01
Is C36500 easy to machine?
Free-machining for a duplex brass — use zero-to-slightly-negative rake carbide or HSS, high speed, light feed, water-soluble coolant; chips break well thanks to the 0.5% Pb.
Can C36500 be welded?
Fusion welding is not recommended (lead causes hot cracking, zinc fumes); join by silver brazing or soft soldering, or seal-weld with matched filler only when unavoidable and with fume extraction.
Can C36500 be formed, bent or molded?
Excellent hot working at 650–780 °C (forging, extrusion, hot rolling); cold formability is only fair — anneal to O61 before severe bending or tube-hole expansion.
What surface finishes work on C36500?
Takes a bright mechanical or chemical polish and accepts Ni/Cr or tin plating; not anodizable — protect decorative surfaces with clear lacquer, and avoid ammonia-bearing cleaners to prevent SCC.

C36500-H01 — frequently asked
What is C36500-H01 used for?
C36500-H01 is typically used for condenser tube sheets, marine hardware and hot-forged fittings. In short: machinable Muntz metal; hot-forging duplex brass; tube-sheet drilling grade.
What is the yield strength of C36500-H01?
C36500-H01 has a typical yield strength of 275 MPa (39.9 ksi) and a tensile strength of 415 MPa (60.2 ksi) — stronger than 57% of copper alloy grades. Strength varies by condition: see the 5 listed tempers.
Is C36500-H01 easy to machine?
Reasonably — machinability is rated good (65/100, better than 76% of copper alloy grades). Free-machining for a duplex brass — use zero-to-slightly-negative rake carbide or HSS, high speed, light feed, water-soluble coolant; chips break well thanks to the 0.5% Pb.
Can C36500-H01 be welded?
Not readily — weldability is rated poor (25/100). Fusion welding is not recommended (lead causes hot cracking, zinc fumes); join by silver brazing or soft soldering, or seal-weld with matched filler only when unavoidable and with fume extraction.
What surface finishes work on C36500-H01?

What is the maximum service temperature of C36500-H01?
C36500-H01 is rated for continuous use to about 150°C (302 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between C36500-M20 and C36500-H02?
M20 is the default condition — standard condition for condenser/heat-exchanger tube plate to ASTM B171; best balance of strength and ductility. H02: highest commonly stocked strength level; choose for stiff machined parts where little forming is needed. Yield strength is 140 MPa in M20 versus 345 MPa in H02.
