Working with CuAg0.10P-R360
Is CuAg0.10P easy to machine?
Gummy and low-rated (~20 % of AISI 1212): use sharp positive-rake polished tools, high speed, low feed and generous soluble-oil coolant to avoid built-up edge.
Can CuAg0.10P be welded?
Excellent for GTAW/GMAW, resistance and induction welding — low residual P means no hydrogen embrittlement; preheat 150–400 °C on thick sections because of high heat conduction.
Can CuAg0.10P be formed, bent or molded?
Very ductile in R200; cold heads, bends and deep-draws readily, with interstage anneals at 400–550 °C (silver keeps annealing needs above plain copper).
What surface finishes work on CuAg0.10P?
Not anodisable; solders and brazes exceptionally well, takes electroplated tin/silver/nickel readily, and polishes to a bright finish that requires lacquer or passivation to stop tarnish.

CuAg0.10P-R360 is typically used for high-temperature brazed conductors, welded busbar assemblies and commutator risers. In short: best weldability of the series; highest-silver deoxidized copper; 99 % IACS after brazing.
What is the yield strength of CuAg0.10P-R360?
CuAg0.10P-R360 has a typical yield strength of 350 MPa (50.8 ksi) and a tensile strength of 385 MPa (55.8 ksi) — stronger than 74% of copper alloy grades. Strength varies by condition: see the 6 listed tempers.
Is CuAg0.10P-R360 easy to machine?
Not especially — machinability is rated poor (32/100, worse than 57% of copper alloy grades). Gummy and low-rated (~20 % of AISI 1212): use sharp positive-rake polished tools, high speed, low feed and generous soluble-oil coolant to avoid built-up edge.
Can CuAg0.10P-R360 be welded?
Yes — weldability is rated excellent (90/100). Excellent for GTAW/GMAW, resistance and induction welding — low residual P means no hydrogen embrittlement; preheat 150–400 °C on thick sections because of high heat conduction.
What surface finishes work on CuAg0.10P-R360?
Not anodisable; solders and brazes exceptionally well, takes electroplated tin/silver/nickel readily, and polishes to a bright finish that requires lacquer or passivation to stop tarnish.
Can CuAg0.10P-R360 be formed, bent or molded?
Very ductile in R200; cold heads, bends and deep-draws readily, with interstage anneals at 400–550 °C (silver keeps annealing needs above plain copper).
What is the maximum service temperature of CuAg0.10P-R360?
CuAg0.10P-R360 is rated for continuous use to about 230°C (446 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between CuAg0.10P-R240 and CuAg0.10P-R360?
R240 is the default condition — default stock condition for rod, bar and profile: balanced strength, machinability and enough ductility for moderate bending. R360: pick for heavily drawn wire and thin profiles needing maximum tensile strength and spring-back. Yield strength is 200 MPa in R240 versus 350 MPa in R360.
